Here They Come Again! The Impacts of Oil and Gas Truck Traffic

/by

Part of the FracTracker Truck Counts Project
By Mary Ellen Cassidy, Community Outreach Coordinator, FracTracker Alliance

I was recently invited by a community member to visit his home. It sits in a valley that is surrounded by drilling pads, as well as compressors and processing stations. While walking down the road that passes directly in front of his home, several caravans of gas trucks roared past and continued far into the evening. Our discussion about the unexpected barrage of this new invasion of intense truck traffic was frequently interrupted by the noise of the diesel engines passing nearby. Along with the noise, truck headlights pierced through the windows of the home, and dust flew up from the nearby road onto his garden.

There are many stories like this about homes and families impacted by the increased truck traffic associated with fracking-related activities. FracTracker is currently working with some of these communities to document the intensity of gas and oil trucks travelling their roads. In response to these concerns we have a launched a pilot Truck Counts project to provide support, resources, and networking opportunities to communities struggling with high volume gas truck traffic.

Preliminary Results

Volunteers in PA, WV, OH and WI have already started to participate in the project, with some interesting results, photos, observations, and suggestions.

TruckCountsChart

To-date, truck counts have varied significantly, as to be expected. Some of the sites where we chose to count passing trucks were very close to drilling activity, and some were more remote. While developing the counting protocol, we often included large equipment and tanker trucks, as well as gas company personnel vehicles (as indicated by white pickup trucks and company logos on the side). While the data vary, the spikes in truck counts do tell the story of a bigger and broader issue – the influx of heavy equipment during certain stages of drilling can be a significant burden on the local community. In total, we counted 676 trucks over 13 sites The average number of trucks that passed by per hour was 44, with a high of 116 an hour, and a low of 5.

About the Project

FracTracker Truck Counts partners with communities to: help identify issues of concern related to high volume gas truck traffic; collect data, photos, videos and narratives related to gas truck traffic; and analyze and share results through shared database and mapping options.

What motivates volunteers to join us in our Truck Counts program? Community concerns include dust, diesel exhaust, spills, accidents, along with other health and safety issues, as well as the cost and inconvenience of deteriorating road conditions resulting from the increased weights and numbers of vehicles. So, what do we already know about the extent of the damages caused by heavy truck traffic?

Public Safety

Several studies have found that shale gas development is strongly linked to increased traffic accidents and that the increases cannot be attributed only to more trucks and people on the road.

Unlike gas truck traffic issues from past oil and gas booms, this recent shale gas boom impacts traffic and public safety in many different ways. The hydraulic fracturing process requires 2,300 to 4,000 truck trips per well, where older drilling techniques needed one-third to one-half as many trips. Another difference is the speed of development that often far outpaces the capacity of communities to build better roads, bridges, install more traffic signals or hire extra traffic officers. Some experts explain increased truck traffic related accidents by pointing to regulatory loopholes such as federal rules that govern how long truckers can stay on the road being less stringent for drivers in the oil and gas industry. Others note that out of state drivers in charge of large heavy duty loads are not always accustomed to the regional weather patterns or the winding, narrow and hilly country roads that they travel.

An Associated Press analysis of traffic deaths in six drilling states shows that in some counties, fatalities have more than quadrupled since 2004 when most other American roads have become much safer in that period (even with growing populations). Marvin Odum, who runs Royal Dutch Shell’s exploration operations in the Americas, said that deadly crashes are “recognized as one of the key risk areas of the business”. Along with the community, gas truck drivers themselves are at risk. According to a study by the National Institute for Occupational Safety and Health, vehicle crashes are the single biggest cause of fatalities to oil and gas workers. The AP study finds that:

  •  In North Dakota drilling counties, the population has soared 43% over the last decade, while traffic fatalities increased 350%. Roads in those counties were nearly twice as deadly per mile driven than the rest of the state
  • From 2009-2013-
    • Traffic fatalities in West Virginia’s most heavily drilled counties…rose 42%. Traffic deaths in the rest of the state declined 8%.
    • In 21 Texas counties where drilling has recently expanded, deaths/100,000 people are up an average of 18 % while for the rest of Texas, they are down by 20%.
    • Traffic fatalities in Pennsylvania drilling counties rose 4%, while in the rest of the state they fell 19 %.
    • New Mexico’s traffic fatalities fell 29%, except in drilling counties, where they only fell 5%.

A separate analysis by Environment America using data from the Upper Great Plans Institute finds that – “While the expanding oil industry in North Dakota has produced many benefits, the expansion has also resulted in an increase in traffic, especially heavy truck traffic. This traffic has contributed to a number of crashes, some of which have resulted in serious injuries and fatalities.” In the Bakken Shale oil region of North Dakota, the number of highway crashes increased by 68% between 2006 and 2010, with the share of crashes involving heavy trucks also increasing over that period.”1

Public health concerns do not end with traffic accidents and fatalities. An additional cost of heavy gas truck traffic is the strain it places on emergency service personnel. A 2011 survey by State Impact Pennsylvania in eight counties found that:

Emergency services in heavily drilled counties face a troubling paradox: Even though their population has fallen in recent years, 911 call activity has spiked — by as high as 46 percent, in one case.” Along with the demands placed on emergency responders from the number of increased calls, it also takes extra time to locate the accidents since many calls are coming from transient drivers who “don’t know which road or township they are in.

In Bradford County, a heavily drilled area, increased traffic has delayed the response times of emergency vehicles. According to an article in The Daily Review, firefighters and emergency response teams are delayed due to the increased number of accidents, gas trucks breaking down, and gas trucks running out of fuel (some companies only allow refueling once a night).

Road Deterioration and Regional Costs

An additional cost often passed on to the impacted communities is infrastructure maintenance. In an article from Business Week, Lynne Irwin, director of Cornell University’s local roads program in Ithaca, New York, states, “Measures to ensure that roads are repaired don’t capture the full cost of damage, potentially leaving taxpayers with the bill.”

This Food and Water Watch Report calculated the financial burden imposed on rural counties by traffic accidents alone, estimating that if the heavy truck accident rate in fracked counties had matched those untouched by the boom, $28 million would have been saved.2

Garrett County is currently struggling with anticipating potential gas traffic and road costs. The Garrett County Shale Gas Advisory Committee uses recent studies from RESI ‘s New York and Pennsylvania data to project gas truck traffic for 6 wells/pad at 22,848 trips/pad and 91,392 total truck trips the first year with increasing numbers for the next 10 years. Like many counties, Garrett County also faces the issue that weights and road use are covered by State, not County code.  There is a possibility, however, that the County could determine best “routes” for the trucks. (This is a prime example of the need and benefit for truck counts.)

Although truck companies and contractors pay permit fees, often they are either insufficient to cover costs or are not accessible to impacted counties. The Texas Tribune reports, “The Senate unanimously passed a joint resolution which would ask voters to approve spending $5.7 billion from the state’s Rainy Day Fund, including $2.9 billion for transportation debt. But little, if any, of that money is likely to go toward repairing roads in areas hit hardest by the drilling boom.”

Commenting on the argument that gas companies already pay their fair share for road damages they cause, George Neal posts calculations on the Damascus Citizens for Sustainability website that lead him to conclude that, although “the average truck pays around 27 times the fuel taxes an average car pays… according to the Texas Department of Transportation, they do 8,000 times the damage per mile driven and drive 8 times as far each year.”

The funds needed to fill the gap between the costs of road repairs and the amount actually paid by the oil and gas companies must come from somewhere. According to a draft report from the New York Department of Transportation looking at potential Marcellus Shale development costs, “The annual costs to undertake these transportation projects are estimated to range from $90 to $156 million for State roads and from $121-$222 million for local roads. There is no mechanism in place allowing State and local governments to absorb these additional transportation costs without major impacts to other programs and other municipalities in the State.”

Along with public safety and infrastructure costs, increased truck traffic associated with unconventional oil and gas extraction is found to be a major contributor to public health costs due to elevated ozone and particulate matter levels from increased emissions of heavy truck traffic and the refining and processing activities required.

In addition to ozone and particulate matter in the air, chemicals used for extraction and development also pose a serious risk. A recent study in the journal of Human and Ecological Health Assessment found that 37% of the chemicals used in drilling operations are volatile and could become airborne. Of those chemicals, more than 89% can cause damage to the eyes, skin, sensory, organs, respiratory and gastrointestinal tracts, or the liver, and 81% can cause harm to the brain and nervous system. Because these chemicals can vaporize, they can enter the body not only through inhalation, but also absorption through the skin.

The Union of Concerned Scientists note that air pollution from traffic may be worsened in North Dakota by the use of unpaved roads that incorporate gravel containing a fibrous mineral called erionite, which has properties similar to asbestos. Trucks driving over such gravel roads can release harmful dust plumes into the air, which could present health risks for workers and area residents

To address and solve these problems associated with heavy truck traffic, information is needed to assess both qualitatively and quantitatively the scope of the increased truck traffic and its impacts on communities. Collection and analysis of data, as well as community input, are needed to both understand the scope of the problem and to inform effective solutions.

Joining FracTracker’s Truck Counts

In response to community concerns about the impacts of increased truck traffic in their community, FracTracker has developed the Truck Count project to document the intensity of oil and gas traffic in your region, map heavy traffic locations, and offer networking opportunities for impacted communities.

Participation in FracTracker’s Truck Counts can provide grassroots organizations with a valuable opportunity to collect local data, engage volunteers, and educate stakeholders and the public. The data, pictures and narratives collected can be used to support concerned citizens’ efforts to reroute traffic from schools, playgrounds and other sensitive areas; to inform decision makers, public health researchers, and transportation agencies; to serve as a potential launching point for more detailed, targeted studies on public health and safety along with economic development analyses; to compare costs and benefits of oil and gas energy sources to the cost and benefits of energy conservation, efficiency and renewable energy.

Also, by sharing your community’s counts and stories on FracTracker.org, you serve other communities by increasing the awareness of the impacts of oil and gas truck traffic nationwide.

FracTracker’s Truck Counts provides the following resources to conduct the counts:

  • information and education on gas and oil truck identification,
  • data sheets for easy counting, and
  • tips for selecting safe and accessible counting locations in your community.

We look forward to working with you and supporting your community. If you are interested in working on this important crowdsourcing project with us, please contact:

Endnotes and References

  1. In addition, a 2013 study from Resources for the Future found that shale gas development is linked to traffic accidents in Pennsylvania with a significant increase in the number of total accidents and accidents involving a heavy truck in counties with a relatively large degree of shale gas development as compared to counties with less (or no) development.
    The 2013 Food and Water Watch Report finds similar correlations. Shale gas drilling was associated with higher incidents of traffic accidents in Pennsylvania. This trend was strongest in counties with the highest density of fracking wells. The decrease in the average annual number of total vehicle crashes was 39% larger in unfracked rural counties than in heavily fracked counties. (analysis based on data from US Census Bureau, PA DEP and PennDOT).
    In a recent Karnes County, Texas analysis “Traffic accidents and fatalities have skyrocketed in the shale boom areas….with an increases of 1,000% in commercial motor vehicle accidents from 2008-2011.
    According to a 2013 Texas Public Threat Safety Report, “In the three Eagle Ford Shale counties where drilling is most active, the number of crashes involving commercial vehicles rose 470 percent between 2009 and 2011. In the 17 counties that make up the Permian Basin, fatal car crashes involving commercial vehicles have nearly tripled from 14 in 2010 to 41 in 2012.
    As a result of heavily using of publicly available infrastructure and services, fracking imposes both immediate and long-term costs on taxpayers. An Environment Texas study reveals that, “Trucks required to deliver water to a single fracking well cause as much damage to roads as 3.5 million car journeys, putting massive stress on roadways and bridges not constructed to handle such volumes of heavy traffic. Pennsylvania estimates that repairing roads affected by Marcellus Shale drilling would cost $265 million”.
  2. Researchers from the RAND Corporation and Carnegie Mellon University looked at the design life and reconstruction cost of roadways in the Marcellus Shale formation in Pennsylvania. Their findings in Estimating the Consumptive Use Costs of Shale Natural Gas Extraction on Pennsylvania Roadways, note that local roads are generally designed to support passenger vehicles, not heavy trucks, and that “the useful life of a roadway is directly related to the frequency and weight of truck traffic using the roadway.” The study’s findings include:
    1. “The estimated road-reconstruction costs associated with a single horizontal well range from $13,000 to $23,000. However, Pennsylvania often negotiates with drilling companies to rebuild smaller roads that are visibly damaged, so the researchers’ conservative estimate of uncompensated roadway damage is $5,000 and $10,000 per well.
    2. While the per-well figure of $5,000-$10,000 appears small, the increasingly large number of wells being drilled means that substantial costs fall on the state: “Because there were more than 1,700 horizontal wells drilled [in Pennsylvania] in 2011, the statewide range of consumptive road costs for that year was between $8.5 and $39 million,” costs paid by state transportation authorities, and thus taxpayers.”

What’s in PA Senate Bill 1378?

/by

State Senator Joseph Scarnati III, from north-central Pennsylvania, has introduced a bill that would redefine the distinction between conventional and unconventional oil and gas wells throughout the state.  In Section 1 of the bill, the sponsors try to establish the purpose of the legislation,  making the case that:

  1. Conventional oil and gas development has a benign impact on the Commonwealth
  2. Many of the wells currently classified as conventional are developed by small businesses
  3. Oil and gas regulations, “must permit the optimal development of oil and gas resources,” as well as protect the citizens and environment.
  4. Previous legislation already does, and should, treat conventional and unconventional wells differently

Certainly, robust debate surrounds each of these points, but they are introductory in nature, not the meat and potatoes of Senate Bill 1378.  What this bill does is re-categorize some of the state’s unconventional wells to the less restrictive conventional category, including:

  1. All oil wells
  2. All natural gas wells not drilled in shale formations
  3. All shale wells above (shallower than) the base of the Elk Group or equivalent
  4. All shale wells below the Elk Group from a formation that can be economically drilled without the use of hydraulic fracturing or multi-lateral bore holes
  5. All wells drilled into any formation where the purpose is not production, including waste disposal and other injection wells

The current distinction is in fact muddled, with one DEP source indicating that the difference is entirely due to whether or not the formation being drilled into is above or below the Elk Group, and another DEP source indicates that the difference is much more nuanced, and really depends on whether the volumes of hydraulic fracturing fluid required to profitably drill into a given formation are generally high or low.

This table shows the number of wells in each formation in Pennsylvania that has both conventional and unconventional wells drilled into it. Data source: DEP, downloaded 7/9/2014.

This table shows the number of distinct wells in each producing formation in Pennsylvania that has both conventional and unconventional wells drilled into it. Data source: DEP, downloaded 7/9/2014.

As one might expect, this ambiguity is represented in the data. The chart at the left shows the number of distinct number of wells by formation, for each producing formation that has both conventional and unconventional wells in the dataset.  Certainly, there could be some data entry errors involved, as the vast majority of Bradford wells are conventional, and almost all of the Marcellus wells are unconventional.  But there seems to be some real confusion with regards to the Oriskany, for example, which is not only deeper than the Elk Group, but the Marcellus formation as well.

While an adjustment to the distinction of conventional and unconventional wells in Pennsylvania is called for, one wonders if the definitions proposed in SB 1378 is the right way to handle it.  If the idea of separating the two is based on the relative impact of the drilling operation, then a much more straightforward metric might be useful, such as providing a cutoff in the amount of hydraulic fracturing fluid used to drill a well.  Further, each of the five parts of the proposed definition serve to make the definition of unconventional wells less inclusive, meaning that additional wells would be subject to the less stringent regulations, and that the state would collect less money from the impact fees that were a part of Act 13 of 2012.

Instead, it is worth checking to see whether the definition of unconventional is inclusive enough.  In May of this year, FracTracker posted a blog about conventional wells that were drilled horizontally in Pennsylvania.


Conventional, non-vertical wells in Pennsylvania. Please click the expanding arrows icon at the top-right corner to access the legend and other map controls. Please zoom in to access data for each location.

These wells require large amounts of hydraulic fracturing fluids, and are already being drilled at depths of only 3,000 feet, and could go as shallow as 1,000 feet.  It’s pretty easy to argue that due to the shallow nature of the wells, and the close proximity to drinking water aquifers, these wells are deserving of even more rigorous scrutiny than those drilled into the Marcellus Shale, which generally ranges from 5,000 to 9,000 feet deep throughout the state.

A summary of the different regulations regarding conventional and unconventional wells can be found from PennFuture.  In general, unconventional wells must be further away from water sources and structures than their conventional counterparts, and the radius of presumptive liability for the contamination of water supplies is 2,500 feet instead of 1,000.

SB 1378 has been re-referred to the Appropriations Committee.

Putting the “Fun” in Fundraisers

/by

By Brook Lenker, Executive Director, FracTracker Alliance

Great turnout and whiskey

Enjoying some whiskey in Pittsburgh

It’s almost July, but just a few weeks ago, FracTracker wrapped up the last of three fundraising events. From a site in San Francisco overlooking the Pacific to a budding distillery in Pittsburgh’s Strip District, friends and colleagues came together to show their support for our work and their concern about the effects of unconventional drilling. If you were able to join us for these events – whatever the motivation, we appreciated your collective, deliberate act of kindness. Thank you!

The gatherings were generally small but lots of fun – full of conversation, positive energy, and, yes, good spirits. At the Cleveland Heights event, we even had live music thanks to the jazzy guitar of Alan Brooks and at all three venues a colorful exhibit of thought-provoking, conversation-stoking maps entitled “Cartography on Canvas.” These events were our first foray into fundraisers. From the experience they’ll be improved and made even more memorable, unique, extraordinary. That’s our goal.

We aim to entice more attendees, enhance our revenue, and, most importantly, grow the network of the informed – not just informed about the activities of FracTracker but of all the groups, efforts, and learnings related to the impacts of extreme hydrocarbon extraction. Soon, another round of events – guaranteed to be mood improving, mind expanding affairs – will be rolled out. Prepare to mark your calendars, join the fun, and make your own social statement!

A special thank you goes out to FracTracker staff, interns, and board members who put in extra time and effort to help ensure the success of these initial fundraisers. Thank you, too, to our incredible door prize and auction item contributors:

Central Penn Pipeline Under Debate

/by

By Karen Edelstein, NY Program Coordinator, FracTracker Alliance

Background

PipelineOver the past month and a half, a new pipeline controversy has been stirring in Pennsylvania. The proposed $2 billion “Central Penn Pipeline” will be built to carry shale gas throughout the country. Starting in Susquehanna County, the 178 mile pipeline will run through Lebanon and Lancaster counties to connect the existing Tennessee Pipeline in the north with the Transco Pipeline in the south.

Oklahoma-based Williams Partners, the company proposing the pipeline, says that the project would help move gas from PA to locations as far south as Georgia and Alabama, in addition to adding relief from higher energy bills. The “Atlantic Sunrise Project,” as it is formally known, would also require the construction of two new 30,000 horse-power compressor stations: “Station 605” along the northern leg of the pipeline in Susquehanna County, as well as “Station 610” on the southern part of the pipeline. The northern part of the proposed pipeline will be 30 inches in diameter and run for about 56 miles; the southern portion will be 42 inches in diameter and about 122 miles long.

According to the US Energy Information Agency (EIA), in 2008, PA had over 8,700 miles of pipeline. Since then, that figure has increased significantly as the shale plays in PA continue to be exploited. Industry maintains that pipelines are the safest method for moving gas from the well to market, and has noted that for safety concerns they have intentionally co-located 36% of the northern part of the pipeline within the rights-of-way of Transco’s or other utility’s pipelines.

Despite the sanguine view of this project by industry, residents have rallied against the pipeline since mid-April, when landowners started getting information packets in the mail about the proposal.

Pipeline Proposal Map

While the exact route of the pipeline has yet to be determined, FracTracker has adapted documents from Oklahoma-based Williams Partners Company to provide this interactive map below. The proposed pipeline is shown in red.

For a full-screen version of this map (with legend), click here.

Proposal Concerns

Public awareness and concern about the pipeline continues to build, as was evident when 1,100 residents attended an open house in Millersville, PA on June 10th hosted by Williams. For more information see this article in Lancaster Online.

The Lancaster County Conservancy has advocated moving the pipeline away from various sensitive habitats including the Tucquan Glen Nature Preserve, Shenk’s Ferry Wildflower Preserve, Fishing Creek, Kelly’s Run, and Rock Springs to preserve the wildlife and beauty of those areas. According to Williams:

The pipeline company must evaluate a number of environmental factors, including potential impacts on residents, threatened and endangered species, wetlands, water bodies, groundwater, fish, vegetation, wildlife, cultural resources, geology, soils, land use, air and noise quality…  More

Despite what the website says, Williams admitted to not analyzing the pipeline route for possible sensitive habitat encroachment, and instead, they will simply follow the existing utility routes.

Williams, according to a report by WGAL Channel 8 in PA “relies on the communities affected to bring up any potential problems.” His statement was backed up when residents in a packed hearing room in Lancaster County voiced their opposition, resulting in Williams Partners now considering extending their pipeline by 2 ½ miles to get around the sensitive natural area at Tucquan Glen. An alternate route to avoid Shenk’s Ferry, however, had not been put forward.

Lancaster Farmland Trust is concerned about the plan for the pipeline to pass through several protected farms, and Lebanon County Commissioner Jo Ellen Litz has also taken a strong stand against the current proposed route. The proposed pipeline would not only go through farmlands, but it is also expected to cross the Appalachian Trail, Swatara State Park, and Lebanon Valley Rails to Trails.

Pipeline impacts are not limited to conservation and agriculture. There is increasing concern that the risks posed by large-diameter, high pressure pipelines such as this one may prevent nearby homeowners from keeping their mortgage loans or homeowner’s insurance. Future purchasers of the property may also encounter difficulty being approved for a mortgage loan or homeowner’s insurance.

While the pipeline company can purchase pipeline easements from property owners, industry can also petition the government to take the land by eminent domain from unwilling property owners. Pipeline rights-of-way acquired through eminent domain for these pipelines could potentially complicate a private property owner’s mortgage financing and homeowner’s insurance.

The final decisions about the siting of the pipeline is ultimately up to FERC, the Federal Energy Regulatory Commission.

Conventional, Non-Vertical Wells in PA

/by

Like most states, the data from the Pennsylvania Department of Environmental Protection do not explicitly tell you which wells have been hydraulically fractured. They do, however, designate some wells as unconventional, a definition based largely on the depth of the target formation:

An unconventional gas well is a well that is drilled into an Unconventional formation, which is defined as a geologic shale formation below the base of the Elk Sandstone or its geologic equivalent where natural gas generally cannot be produced except by horizontal or vertical well bores stimulated by hydraulic fracturing.

While Pennsylvania has been producing oil and gas since before the Civil War, the arrival of unconventional techniques has brought greater media scrutiny, and at length, tougher regulations for Marcellus Shale and other deep wells. We know, however, that some companies are increasingly looking at using the combination of horizontal drilling and hydraulic fracturing in much shallower formations, which could be of greater concern to those reliant upon well water than wells drilled into deeper unconventional formations, such as the Marcellus Shale. The chance of methane or fluid migration through karst or other natural fissures in the underground rock formations increase as the distance between the hydraulic fracturing activity and groundwater sources decrease, but the new standards for unconventional wells in the state don’t apply.

The following chart summarizes data for wells through May 16, 2014 that are not drilled vertically, but that are considered to be conventional, based on depth:

These wells are listed as conventional, but are not drilled vertically.

These wells are listed as conventional, but are not drilled vertically.

Note that there have already been more horizontal wells in this group drilled in 2014 than any previous year, showing that the trend is increasing sharply.

Of the 26 horizontal wells, 12 are considered oil wells, five are gas wells, five are storage wells, three are combination oil and gas, and one is an injection well.  These 177 wells have been issued a total of 97 violations, which is a violation per well ratio of 62 percent.  429 permits in have been issued in Pennsylvania to date for non-vertical wells classified as conventional.  Greene county has the largest number of horizontal conventional wells, with eight, followed by Bradford (5) and Butler (4) counties.

We can also take a look at this data in a map view:

Water Use in WV and PA

Water Resource Reporting and Water Footprint from Marcellus Shale Development in West Virginia and Pennsylvania

Report and summary by Meghan Betcher and Evan Hansen, Downstream Strategies; and Dustin Mulvaney, San Jose State University

GasWellWaterWithdrawals The use of hydraulic fracturing for natural gas extraction has greatly increased in recent years in the Marcellus Shale. Since the beginning of this shale gas boom, water resources have been a key concern; however, many questions have yet to be answered with a comprehensive analysis. Some of these questions include:

  • What are sources of water?
  • How much water is used?
  • What happens to this water following injection into wells?

With so many unanswered questions, we took on the task of using publically available data to perform a life cycle analysis of water used for hydraulic fracturing in West Virginia and Pennsylvania.

Summary of Findings

Some of our interesting findings are summarized below:

  • In West Virginia, approximately 5 million gallons of fluid are injected per fractured well, and in Pennsylvania approximately 4.3 million gallons of fluid are injected per fractured well.
  • Surface water taken directly from rivers and streams makes up over 80% of the water used in hydraulic fracturing in West Virginia, which is by far the largest source of water for operators. Because most water used in Marcellus operations is withdrawn from surface waters, withdrawals can result in dewatering and severe impacts on small streams and aquatic life.
  • Most of the water pumped underground—92% in West Virginia and 94% in Pennsylvania—remains there, lost from the hydrologic cycle.
  • Reused flowback fluid accounts for approximately 8% of water used in West Virginia wells.
  • Approximately one-third of waste generated in Pennsylvania is reused at other wells.
  • As Marcellus development has expanded, waste generation has increased. In Pennsylvania, operators reported a total of 613 million gallons of waste, which is approximately a 70% increase in waste generated between 2010 and 2011.
  • Currently, the three-state region—West Virginia, Pennsylvania, and Ohio—is tightly connected in terms of waste disposal. Almost one-half of flowback fluid recovered in West Virginia is transported out of state. Between 2010 and 2012, 22% of recovered flowback fluid from West Virginia was sent to Pennsylvania, primarily to be reused in other Marcellus operations, and 21% was sent to Ohio, primarily for disposal via underground injection control (UIC) wells. From 2009 through 2011, approximately 5% of total Pennsylvania Marcellus waste was sent to UIC wells in Ohio.
  • The blue water footprint for hydraulic fracturing represents the volume of water required to produce a given unit of energy—in this case one thousand cubic feet of gas. To produce one thousand cubic feet of gas, West Virginia wells require 1-3 million gallons of water and Pennsylvania wells required 3-4 million gallons of water.

Table 1. Reported water withdrawals for Marcellus wells in West Virginia (million gallons, % of total withdrawals, 2010-2012)

WV Water Withdrawals

Source: WVDEP (2013a). Note: Surface water includes lakes, ponds, streams, and rivers. The dataset does not specify whether purchased water originates from surface or groundwater. As of August 14, 2013, the Frac Water Reporting Database did not contain any well sites with a withdrawal “begin date” later than October 17, 2012. Given that operators have one year to report to this database, the 2012 data are likely very incomplete.

As expected, we found that the volumes of water used to fracture Marcellus Shale gas wells are substantial, and the quantities of waste generated are significant. While a considerable amount of flowback fluid is now being reused and recycled, the data suggest that it displaces only a small percentage of freshwater withdrawals. West Virginia and Pennsylvania are generally water-rich states, but these findings indicate that extensive hydraulic fracturing operations could have significant impacts on water resources in more arid areas of the country.

While West Virginia and Pennsylvania have recently taken steps to improve data collection and reporting related to gas development, critical gaps persist that prevent researchers, policymakers, and the public from attaining a detailed picture of trends. Given this, it can be assumed that much more water is being withdrawn and more waste is being generated than is reported to state regulatory agencies.

Data Gaps Identified

We encountered numerous data gaps and challenges during our analysis:

  • All data are self-reported by well operators, and quality assurance and quality control measures by the regulatory agencies are not always thorough.
  • In West Virginia, operators are only required to report flowback fluid waste volumes. In Pennsylvania, operators are required to report all waste fluid that returns to the surface. Therefore in Pennsylvania, flowback fluid comprises only 38% of the total waste which means that in West Virginia, approximately 62% of their waste is not reported, leaving its fate a mystery.
  • The Pennsylvania waste disposal database indicates waste volumes that were reused, but it is not possible to determine exactly the origin of this reused fluid.
  • In West Virginia, withdrawal volumes are reported by well site rather than by the individual well, which makes tracking water from withdrawal location, to well, to waste disposal site very difficult.
  • Much of the data reported is not publically available in a format that allows researchers to search and compare results across the database. Many operators report injection volumes to FracFocus; however, searching in FracFocus is cumbersome – as it only allows a user to view records for one well at a time in PDF format. Completion reports, required by the Pennsylvania Department of Environmental Protection (PADEP), contain information on water withdrawals but are only available in hard copy at PADEP offices.

In short, the true scale of water impacts can still only be estimated. There needs to be considerable improvements in industry reporting, data collection and sharing, and regulatory enforcement to ensure the data are accurate. The challenge of appropriately handling a growing volume of waste to avoid environmental harm will continue to loom large unless such steps are taken.

PA Production and Waste Data Updated

/by

Every six months, the Pennsylvania Department of Environmental Protection (PADEP) publishes production and waste data for all unconventional wells drilled in the Commonwealth.  These data are self-reported by the industry to PADEP, and in the past, there have been numerous issues with the data not being reported in a timely fashion.  Therefore, the early versions of these two datasets are often incomplete.  For that reason, I now like to wait a few weeks before analyzing and mapping this data, so as to avoid false conclusions.  That time has now come.


This map contains production and waste totals from unconventional wells in Pennsylvania from July to December, 2013. Based on data downloaded March 6, 2014. Also included are facilities that received the waste produced by these wells. To access the legend and other map controls, please click the expanding arrows icon at the top-right corner of the map.

Production

Top 20 unconventional gas producers in PA, from July to December 2013. The highest values in each column are highlighted in red.

Table 1: Top 20 unconventional gas producers in PA, from July to December 2013. Highest values in each column are highlighted in red.

Production values can be summarized in many ways. In this post, we will summarize the data, first by operator, then by county. For operators, we will take a look at all operators on the production report, and see which operator has the highest total production, as well as production per well (Table 1).

It is important to note that not all of the wells on the report are actually in production, and not all of the ones that are produce for the entire cycle. However, there is some dramatic variance in the production that one might expect from an unconventional well in Pennsylvania that correlates strongly with which operator drilled the well in question.  For example, the average Cabot well produces ten times the gas that the average Atlas well does.  Even among the top two producers, the average Chesapeake well produces 2.75 times as much as the average Range Resources well.

The location of the well is the primary factor in regards to production values.  74 percent of Atlas’ wells are in Greene and Fayette counties, in southwestern Pennsylvania, while 99 percent of Cabot’s wells are in Susquehanna County.  Similarly, 79 percent of Range Resources’ wells are in the its southwestern PA stronghold of Washington County, while 62 percent of Chesapeake’s wells are in Bradford county, in the northeast.

Table 2: PA unconventional gas production by county, from July to December 2013

Altogether, there are unconventional wells drilled in 38 Pennsylvania counties, 33 of which have wells that are producing (see Table 2).  And yet, fully 1 trillion cubic feet (Tcf) of t he 1.7 Tcf produced by unconventional wells during the six month period in Pennsylvania came from the three northeastern counties of Susquehanna, Bradford, and Lycoming.

While production in Greene County does not compare to production in Susquehanna, this disparity still does not account for the really poor production of Atlas wells, as that operator averages less than one fourth of the typical well in the county.  Nor can we blame the problem on inactive wells, as 84 of their 85 wells in Greene County are listed as being in production.  There is an explanation, however.  All of  these Atlas wells were drilled from 2006 through early 2010, so none of them are in the peak of their production life cycles.

There is a different story in Allegheny County, which has a surprising high per well yield for a county in the southwestern part of the state.  Here, all of the wells on the report were drilled between 2008 and 2013, and are therefore in the most productive part of the well’s life cycle.  Only the most recent of these wells is listed as not being in production.

Per well production during the last half of 2013 for unconventional wells in Pennsylvania by year drilled.

Table 3: Per well production during last half of 2013 for PA unconventional wells by spud year

Generally speaking, the further back a well was originally drilled, the less gas it will produce (see Table 3). At first glance, it might be surprising to note that the wells drilled in 2012 produced more gas than those drilled in 2013, however, as the data period is for the last half of 2013, there were a number of wells drilled that year that were not in production for the entire data cycle.

In addition to gas, there were 1,649,699 barrels of condensate and 182,636 barrels of oil produced by unconventional wells in Pennsylvania during the six month period. The vast majority of both of these resources were extracted from Washington County, in the southwestern part of the state.  540 wells reported condensate production, while 12 wells reported oil.

Waste

There are eight types of waste detailed in the Pennsylvania data, including:

  • Basic Sediment (Barrels) – Impurities that accompany the desired product
  • Drill Cuttings (Tons) – Broken bits of rock produced during the drilling process
  • Flowback Fracturing Sand (Tons) – Sand used as proppants during hydraulic fracturing that return to the surface
  • Fracing Fluid Waste (Barrels) – Fluid pumped into the well for hydraulic fracturing that returns to the surface.  This includes chemicals that were added to the well.
  • Produced Fluid (Barrels) – Naturally occurring brines encountered during drilling that contain various contaminants, which are often toxic or radioactive
  • Servicing Fluid (Barrels) – Various other fluids used in the drilling process
  • Spent Lubricant (Barrels) – Oils used in engines as lubricants

This table shows solid and liquid waste totals for the ten counties that produced the most liquid waste over the six month period.

Table 6: Solid & liquid waste totals for the 10 counties that produced the most liquid waste over the 6 month period

There are numerous methods for disposing of drilling waste in Pennsylvania (see Table 4). Some of the categories include recycling for future use, others are merely designated as stored temporarily, and others are disposed or treated at a designated facility.  One of the bright points of the state’s waste data is that it includes the destination of that waste on a per well basis, which has allowed us to add receiving facilities to the map at the top of the page.

As eight data columns per table is a bit unwieldy, we have aggregated the types by whether they are solid (reported in tons) or liquid (reported in 42 gallon barrels).  Because solid waste is produced as a result of the drilling and fracturing phases, it isn’t surprising that the old Atlas wells produced no new solid waste (see Table 5).  Chevron Appalachia is more surprising, however, as the company spudded 46 wells in 2013, 12 of which were started during the last half of the year.  However, Chevron’s liquid waste totals were significant, so it is possible that some of their solid waste was reported, but miscategorized.

As with production, location matters when it comes to the generation of waste from these wells. But while the largest gas producing counties were led by three counties in the northeast, liquid waste production is most prolific in the southwest (see Table 6).

Table 7: PA Unconventional operators with the most wells that produced gas, oil, and/or condensate, but no amount of waste. The column on the right shows total number of wells that are indicated as producing, for that same operator, regardless of waste production.

Table 7: PA unconventional operators with the most wells that produced gas, oil, and/or condensate, but no amount of waste.

Finally, we will take a look at the 359 wells that are indicated as in production, yet were not represented on the waste report as of March 6th.  These remarkable wells are run by 38 different operators, but some companies are luckier with the waste-free wells than their rivals.  As there was a six-way tie for 10th place among these operators, as sorted by the number or wells that produce gas, condensate, or oil but not waste, we can take a look at the top 15 operators in this category (see Table 7). Of note, gas quantity only includes production from these wells. Column on the right shows total number of wells that are indicated as producing, for that same operator, regardless of waste production.

114 of Southwestern Energy’s 172 producing wells were not represented on the waste report as of March 6th, representing just under two thirds of the total.  In terms of the number of waste-free wells, Atlas was second, with 55.  As for the highest percentage, Dominon, Hunt, and Texas Keystone all managed to avoid producing any waste at all for each of their seven respective producing wells, according to this self-reported data.

Over 1.1 Million Active Oil and Gas Wells in the US

Many people ask us how many wells have been hydraulically fractured in the United States.  It is an excellent question, but not one that is easily answered; most states don’t release data on well stimulation activities.  Also, since the data are released by state regulatory agencies, it is necessary to obtain data from each state that has oil and gas data to even begin the conversation.  We’ve finally had a chance to complete that task, and have been able to aggregate the following totals:

Oil and gas summary data of drilled wells in the United States.

Oil and gas summary data of drilled wells in the United States.

 

While data on hydraulically fractured wells is rarely made available, the slant of the wells are often made accessible.  The well types are as follows:

  • Directional:  Directional wells are those where the top and the bottom of the holes do not line up vertically.  In some cases, the deviation is fairly slight.  These are also known as deviated or slant wells.
  • Horizontal:  Horizontal wells are directional wells, where the well bore makes something of an “L” shape.  States may have their own definition for horizontal wells.  In Alaska, these wells are defined as those deviating at least 80° from vertical.  Currently, operators are able to drill horizontally for several miles.
  • Directional or Horizontal:  These wells are known to be directional, but whether they are classified as horizontal or not could not be determined from the available data.  In many cases, the directionality was determined by the presence of directional sidetrack codes in the well’s API number.
  • Vertical:  Wells in which the top hole and bottom hole locations are in alignment.  States may have differing tolerances for what constitutes a vertical well, as opposed to directional.
  • Hydraulically Fractured:  As each state releases data differently, it wasn’t always possible to get consistent data.  These wells are known to be hydraulically fractured, but the slant of the well is unknown.
  • Not Fractured:  These wells have not been hydraulically fractured, and the slant of the well is unknown.
  • Unknown:  Nothing is known about the slant, stimulation, or target formation of the well in question.
  • Unknown (Shale Formation):  Nothing is known about the slant or stimulation of the wells in question; however, it is known that the target formation is a major shale play.  Therefore, it is probable that the well has been hydraulically fractured, with a strong possibility of being drilled horizontally.

Wells that have been hydraulically fractured might appear in any of the eight categories, with the obvious exception of “Not Fractured.”  Categories that are very likely to be fractured include, “Horizontal”, “Hydraulically Fractured”, and “Unknown (Shale Formation),” the total of which is about 32,000 wells.  However, that number doesn’t include any wells from Texas or Colorado, where we know thousands wells have been drilled into major shale formations, but the data had to be placed into categories that were more vague.

Oil and gas wells in the United States, as of February 2014. Location data were not available for Maryland (n=104), North Carolina (n=2), and Texas (n=303,909).  To access the legend and other map tools, click the expanding arrows icon in the top-right corner.

The standard that we attempted to reach for all of the well totals was for wells that have been drilled but have not yet been plugged, which is a broad spectrum of the well’s life-cycle.  In some cases, decisions had to be made in terms of which wells to include, due to imperfect metadata.

No location data were available for Maryland, North Carolina, or Texas.  The first two have very few wells, and officials in Maryland said that they expect to have the data available within about a month.  Texas location data is available for purchase, however such data cannot be redistributed, so it was not included on the map.

It should not be assumed that all of the wells that are shown in  the map above the shale plays and shale basin layers are actually drilled into shale.  In many cases, however, shale is considered a source rock, where hydrocarbons are developed, before the oil and gas products migrate upward into shallower, more conventional formations.

Songbird Nurseries of Pennsylvania

/by

Guest Blog by Paul T. Zeph, Director of Conservation for Audubon Pennsylvania

Millions of small, beautiful, colorful songbirds that live in the tropics for most of the year venture north each spring to Pennsylvania to nest in our deep, quiet forests—forests that are now in danger of being fracked apart into industrial zones of natural gas extraction.

The names of these birds are often described by their vibrant colors:  Black-throated Blue Warbler, Scarlet Tanager, Cerulean Warbler, or Rose-breasted Grosbeak. Here, in the deep remnants of Penn’s Woods, they find an abundance of caterpillars and other insects that are critical protein for raising baby birds. Once the young are fledged and finding food on their own, the parents and juveniles head back south in early fall to their “non-breeding” habitat, which is more accurately called the Neotropics; that is, the New World tropics of the Caribbean, Central America and South America.

Most of these Neotropical migrants cannot nest successfully in small woodlots or fragmented forests, and depend upon large, undisturbed tracts of woodland that we call “core” forests.  These are forests that are at least 300 feet from a permanent edge – such as a road, utility corridor, or housing development.  Pennsylvania still has some very large forest blocks, primarily in the northern tier of the state, that serve as bird “nurseries”—places where the nest density is high and many species are successfully fledging young.

A recently-completed Pennsylvania Breeding Bird Atlas is undergoing analysis by many researchers, and the data is helping us to identify the “best of the best” places in the state needed to sustain populations of our Neotropical visitors, for which we have a North American responsibility.  Not surprisingly, these quiet, large blocks of forest are also favorite places for humans to use for passive recreation, relaxation, and spiritual renewal.  If you want a quiet, peaceful place to escape the modern world for a weekend, look for places frequented in June by Blackburnian Warblers or Blue-headed Vireos.

Since many populations of our Neotropical species have been dramatically declining over the past 50 years, we need to protect as much nesting habitat as possible.  In 100 years, we will probably see many species disappear from Pennsylvania altogether due to fragmentation and climate change.  Our northern forest blocks may be a last refuge for a number of bird and other animal species that cannot survive in our sprawling suburbs or the ecological changes that will come with a warming planet.

Fracking is a heavily industrialized activity that not only causes short-term fragmentation, noise, and ecological disruption, but can lead to long-term ecological collapse of healthy, intact forest blocks.  Birds are only one of many types of animals that are impacted by the vast array of fracking infrastructure that is becoming all-too-common in our state’s quiet and shady bird nurseries, trout streams, and recreation areas:  widened roads letting in sunlight and nest predators; long, wide pipelines creating miles of permanent edge; thousands of acres of forest floor buried under compacted gravel pads; rain events carrying road and well pad gravel into sensitive headwater streams, burying aquatic life.

We have precious few public lands left in Pennsylvania that have not been leased for mineral extraction.  We must do all that we can to prevent leasing of lands where the state owns the mineral rights; and, where the rights are severed and owned by another, we must find compromises and solutions that keep as much of the forest intact as possible.

Unconventional drilling waste impoundment

A partner in data-crunching, SkyTruth, is seeking volunteers to find waste impoundments from unconventional oil and gas drilling in Pennsylvania.

SkyTruth is our “eye in the sky” when it comes to tracking everything from the plume of the BP Oil Spill to flaring in the Bakken. They use remote sensing and mapping technologies to better understand the extent and impacts from a wide spectrum of industrial activities.

With the rapid increase in unconventional drilling in PA since 2005, this endeavor is incredibly important; waste impoundments may release chemicals into the air that are dangerous to health. To assess the true impacts, however, we need to know how close people are living to these potential air pollution sources.

As anyone who has seen a drilling site knows, hydraulic fracturing (e.g. fracking) requires a lot of water and often produces a lot of waste. This means that to map where all of the waste impoundments are located in PA will require many volunteers. The beauty of crowdsourcing is that a group can contribute a significantly larger number of observations much more quickly than could ever be possible with a few non-profit staffers.

“What can I do?” SkyTruth needs your well-trained eyes for their new project called FrackFinder PA: Project Moor Frog. In the comfort of your home, they’ll ask you to identify ponds that are large enough to be a part of oil and gas extraction activities from satellite photos taken above the sites.  Learn more  | Get involved  |  Data results
