FracTracker Alliance and the CREATE Lab at CMU recently launched a pilot project to track the transportation of volatile crude oil as it passes through Pennsylvania and specifically the Pittsburgh region.
For a bit of background, we were specifically interested in how many cars marked with either a 1075 or 1267 placard (shown below). 1075 placards designate cars that are carrying or recently carried (not yet cleaned out) butane, LPG, propane, or a flammable gas. Alternatively, 1267 placards are warning signs for cars carrying petroleum crude oil or some sort of flammable liquid.
DOT Placard 1075 Butane, LPG, Propane, Flammable Gas, Class 2
DOT Placard 1267 Petroleum Crude Oil, Flammable Liquid, Class 3
Oil Train Counts
Over 11 hours we counted 28 trains, 10 of which contained at least one car with the 1075 or 1267 placard. Most of these trains were quite long, with 28 trains hauling 2,874 cars.
The largest inbound train with the 1267 placard that we identified and estimated to be full was hauling 97 crude tankers. If they were indeed full, this train carried between 2.5 and 3.4 million gallons of crude oil. As a point of reference, the Lac-Mégantic derailment that occurred in 2013 in Quebec and killed 47 people was only carrying 74 Bakken crude cars.
Of the 2,874 cars that we counted, 360 were carrying some sort of oil product. Of those oil cars, approximately 70% were of the 1267 variety (Figure 1).
Figure 1. Ratio of oil cars to total documented by volunteers in Pittsburgh, PA over 11 hours
Speed Matters
The fastest oil train that we observed was going approximately 50 MPH. This train was likely full, based on load estimates and the direction it was traveling. This speed violates a voluntary compliance that crude trains run <40 MPH through high-threat areas. A train that derailed in Lynchburg, VA in April was traveling just 24 mph. Our counting location would likely qualify as a high-threat area, as we were near Neville Island, relatively close to ALCOSAN and the City of Pittsburgh, and just a few yards from the Ohio River and residential homes.
While Pittsburgh certainly has its share of oil trains, concern over the dangers that these trains pose to towns along its tracks extends far beyond the Pittsburgh area. Groups as far as California have gathered together to monitor train traffic. We hope that by tracking and monitoring the number of oil trains over time, we can begin to understand the risks that these trains pose should an incident occur.
The Data Collection Process
Here is how we collected the above data: On October 21st our staff, interns, and generous volunteers spent designated shifts observing the passing of trains and the contents of their cars between about 7:30 AM and 6:30 PM. Under the cover of a pop-up shelter, teams of at least three participants videotaped trains as they passed in either direction, counted and recorded the number of cars that they carried, and most importantly identified and counted specific placards that labeled individual cars as oil-carrying.
Many thanks to the groups who helped with this pilot count: volunteer citizens, Group Against Smog and Pollution, Three Rivers Waterkeeper, Women for a Healthy Environment, our interns from Pitt and Duquesne, and CMU staff.
The CREATE Lab then reviewed and analyzed the collected information and video feed. You can take a look at some of the high-resolution video feed they were able to collect with their BreatheCam. If you have specific questions about the train counting protocol or would like to set up one of your own, please contact us.

As my first year in The Bay Area of California comes to a conclusion and the summer once again turns into fall I realize how much more this time of year meant for me living on the east coast. For us lucky ducks living in the Bay Area, fall is perpetual. With the California drought seasons blur together, but back home in Pennsylvania and New York, fall marks a much appreciated relief from 90°F+ days. Regardless of where you live certain fall activities are universal, including hockey, postseason baseball, football, and most importantly for kids – going back to school.
In California alone, almost 6.24 million students from kindergarten to 12th grade are enrolled and attend classes at one of the 10,366 state “campuses.” State-recognized schools range in size from under a dozen students to a maximum 2013/2014 enrollment of 5,229. When so many children are together in one space, they share much more than just the scholarship, social development, and the occasional but inevitable flu virus. They share the same environmental media (air, water, soil) and are therefore exposed to the same environmental contaminants.
To understand who among this vulnerable population is subject to potential health impacts, the FracTracker Alliance has put together a report analyzing the demographic characteristics of schools located near oil and gas extraction activity. An interactive map of the data that was analyzed is shown below, as are the points of the report. The full report can be found here:
In the background, less than 1,200 feet from the school is
an oil well (API 403043765) that was hydraulically fractured.
Key Findings of School Analysis:
There are 485 active/new oil and gas wells within 1 mile of a school and 177 active/new oil and gas wells within 0.5 miles of a school.
There are 352,784 students who attend school within 1 mile of an oil or gas well, and 121,903 student who attend school within 0.5 miles of an oil or gas well.
There are 78 stimulated wells drilled within 1 mile of a school and 14 stimulated wells drilled within 0.5 miles of a school.
There are 61,612 students who attend school within 1 mile of a stimulated oil or gas well, and 12,362 students who attend school within 0.5 miles of a stimulated oil or gas well.
School Districts with greater Hispanic and non-white student enrollment are more likely to contain more oil and gas drilling and stimulation.
Schools campuses with greater Hispanic and non-white student enrollment are more likely to be closer to more oil and gas drilling and stimulation.
Students attending school within 1 mile of oil and gas wells are predominantly non-white (79.6%), and 60.3% are Hispanic.
The top 11 school districts with the highest well counts are located the San Joaquin Valley with 10 districts in Kern County and the other just north of Kern in Fresno County.
The two districts with the highest well counts are in Kern County; Taft Union High School District, host to 33,155 oil and gas wells, and Kern Union High School District, host to 19,800 oil and gas wells.
Of the schools with the most wells within a 1 mile radius, 8/10 are located in Los Angeles County.
Report Map
The interactive map below allows the user to compare the demographical profiles of school districts with oil and gas drilling and stimulation activity. Non-white enrollment percentages of school districts are displayed in shades of blue. Overlaid with red are the relative counts of stimulated and/or non-stimulated oil and gas wells. The highest counts of wells are hosted in school districts located in the Central (San Joaquin) Valley and along California’s south coast. Geologically, these areas lay above the Monterey Shale – the 50 million year sedimentary basin producing California’s oil reserves.

OH Utica Production, Water Usage, and Waste Disposal by County Part II of a Multi-part Series
By Ted Auch, Great Lakes Program Coordinator, FracTracker Alliance
In this part of our ongoing “Water-Energy Nexus” series focusing on Water and Water Use, we are looking at how counties in Ohio differ between how much oil and gas are produced, as well as the amount of water used and waste produced. This analysis also highlights how the OH DNR’s initial Utica projections differ dramatically from the current state of affairs. In the first article in this series, we conducted an analysis of OH’s water-energy nexus showing that Utica wells are using an ave. of 5 million gallons/well. As lateral well lengths increase, so does water use. In this analysis we demonstrate that:
Drillers have to use more water, at higher pressures, to extract the same unit of oil or gas that they did years ago,
Where production is relatively high, water usage is lower,
As fracking operations move to the perimeter of a marginally productive play – and smaller LLCs and MLPs become a larger component of the landscape – operators are finding minimal returns on $6-8 million in well pad development costs,
Market forces and Muskingum Watershed Conservancy District (MWCD) policy has allowed industry to exploit OH’s freshwater resources at bargain basement prices relative to commonly agreed upon water pricing schemes.
At current prices1, the shale gas industry is allocating < 0.27% of total well pad costs to current – and growing – freshwater requirements. It stands to reason that this multi-part series could be a jumping off point for a more holistic discussion of how we price our “endless” freshwater resources here in OH.
In an effort to better understand the inter-county differences in water usage, waste production, and hydrocarbon productivity across OH’s 19 Utica Shale counties we compiled a data-set for 500+ Utica wells which was previously used to look at differenced in these metrics across the state’s primary industry players. The results from Table 1 below are discussed in detail in the subsequent sections.

Production
Total
It will come as no surprise to the reader that OH’s Utica oil and gas production is being led by Carroll County, followed distantly by Harrison, Noble, Belmont, Guernsey and Columbiana counties. Carroll has produced 3.7 million barrels of oil to date, while the latter have combined to produce an additional 4.5 million barrels. Carroll wells have been in production for nearly 67,000 days2, while the aforementioned county wells have been producing for 42,886 days. The remaining counties are home to 49 wells that have been in production for nearly 8,800 days or 7% of total production days in Ohio.
Combined with the state’s remaining 49 producing wells spread across 13 counties, OH’s Utica Shale has produced 8.3 million barrels of oil as well as 251,844,311 Mcf3 of natural gas and 5.4 million barrels of brine. Oil and natural gas together have an estimated value of $2.99 billion ($213 million per quarter)4 assuming average oil and natural gas prices of $96 per barrel and $8.67 per Mcf during the current period of production (2011 to Q2-2014), respectively.
Potential Revenue at Different Severance Tax Rates:
Current production tax, 0.5-0.8%: $19 million ($1.4 Million Per Quarter (MPQ). At this rate it would take the oil and gas industry 35 years to generate the $4.6 billion in tax revenue they proposed would be generated by 2020.
Proposed, 1% gas and 4% oil: At Governor Kasich’s proposed tax rate, $2.99 billion translates into $54 million ($3.9 MPQ). It would still take 21 years to return the aforementioned $4.6 billion to the state’s coffers.
The bottom-line is that a production tax of 11-25% or more ($24-53 MPQ) would be necessary to generate the kind of tax revenue proposed by the end of 2020. This type of O&G taxation regime is employed in the states of Alaska and Oklahoma.
From an outreach and monitoring perspective, effects on air and water quality are two of the biggest gaps in our understanding of shale gas from a socioeconomic, health, and environmental perspective. Pulling out a mere 1% from any of these tax regimes would generate what we’ll call an “Environmental Monitoring Fee.” Available monitoring funds would range between $194,261 and $1.8 million ($16 million at 55%). These monies would be used to purchase 2-21 mobile air quality devices and 10-97 stream quantity/quality gauges to be deployed throughout the state’s primary shale counties to fill in the aforementioned data gaps.
Per-Day Production
On a per-day oil production basis, Belmont and Columbiana (20 barrels per day (BPD)) are overshadowed by Washington (59 BPD) and Muskingum (40 BPD) counties’ four giant Utica wells. Carroll is able to maintain such a high level of production relative to the other 15 counties by shear volume of producing wells; Noble (268 BPD), Guernsey (147 BPD), and Harrison (136 BPD) counties exceed Carroll’s production on a per-day basis. The bottom of the league table includes three oil-free wells in Ashland, Knox, and Medina, as well as seventeen <10 BPD wells in Jefferson and Mahoning counties.
With respect to natural gas, Harrison (1,840 Mcf per day (MPD)) and Guernsey counties are replaced by Monroe (7,348 MPD) and Jefferson (2,447 MPD) counties’ 26 Utica wells. The range of production rates for natural gas is represented by the king of natural gas producers, Belmont County, producing 8,578 MPD on the high end and Mahoning and Coshocton counties in addition to the aforementioned oil dry counties on the low end. Four of the five oil- or gas-dry counties produce the least amount of brine each day (BrPD). Coshocton, Medina, and Noble county Utica wells are currently generating 267-363 barrels of BrPD, with an additional seven counties generating 100-200 BrPD. Only four counties – 1.2% of OH Utica wells – are home to unconventional wells that generate ≤ 30 BrPD.
Water Usage
Freshwater is needed for the hydraulic fracturing process during well stimulation. For counties where we had compiled a respectable sample size we found that Monroe and Noble counties are home to the Utica wells requiring the greatest amount of freshwater to obtain acceptable levels of productivity (Figure 1). Monroe and Noble wells are using 10.6 and 8.8 million gallons (MGs) of water per well. Coshocton is home to a well that required 10.8 MGs, while Muskingum and Washington counties are home to wells that have utilized 10.2 and 9.5 MGs, respectively. Belmont, Guernsey, and Harrison reflect the current average state of freshwater usage by the Utica Shale industry in OH, with average requirements of 6.4, 6.9, and 7.2 MGs per well. Wells in eight other counties have used an average of 3.8 (Mahoning) to 5.4 MGs (Tuscarawas). The counties of Ashland, Knox, and Medina are home to wells requiring the least amount of freshwater in the range of 2.2-2.9 MGs. Overall freshwater demand on a per well basis is increasing by 220,500-333,300 gallons per quarter in Ohio with percent recycled water actually declining by 00.54% from an already trivial average of 6-7% in 2011 (Figure 2).
Figure 1. Average water usage (gallons) per Utica well by county
Figure 2. Average water usage (gallons) on per well basis by OH Utica Shale industry, shown quarterly between Q3-2010 & Q2-2014.
Belmont County’s 30+ Utica wells are the least efficient with respect to oil recovery relative to freshwater requirements, averaging 7,190 gallons of water per gallon of oil (Figure 3). A distant second is Jefferson County’s 14 wells, which have required on average 3,205 gallons of water per gallon of oil. Columbiana’s 26 Utica wells are in third place requiring 1,093 gallons of freshwater. Coshocton, Mahoning, Monroe, and Portage counties are home to wells requiring 146-473 gallons for each gallon of oil produced.
Belmont County’s 14 Utica wells are the least efficient with respect to natural gas recovery relative to freshwater requirements (Figure 4). They average 1,306 gallons of water per Mcf. A distant second is Carroll County’s 250+ wells, which have injected 520 gallons of water 7,000+ feet below the earth’s service to produce a single Mcf of natural gas. Muskingum’s Utica well and Noble County’s 39 wells are the only other wells requiring more than 100 gallons of freshwater per Mcf. The remaining nine counties’ wells require 15-92 gallons of water to produce an Mcf of natural gas.

Figure 4. Average water usage (gallons) per unit of gas produced (Mcf) across 19 Ohio Utica counties
Waste Production
The aforementioned Jefferson wells are the least efficient with respect to waste vs. product produced. Jefferson wells are generating 12,728 gallons of brine per gallon of oil (Figure 5).6 Wells from this county are followed distantly by the 32 Belmont and 26 Columbiana county wells, which are generating 5,830 and 3,976 gallons of brine per unit of oil.5 The remaining counties (for which we have data) are using 8-927 gallons of brine per unit of oil; six counties’ wells are generating <38 gallons of brine per gallon of oil.
Figure 5. Average brine production (gallons) per gallon of oil produced per day across 19 Ohio Utica Counties
The average Utica well in OH is generating 820 gallons of fracking waste per unit of product produced. Across all OH Utica wells, an average of 0.078 gallons of brine is being generated for every gallon of freshwater used. This figure amounts to a current total of 233.9 MGs of brine waste produce statewide. Over the next five years this trend will result in the generation of one billion gallons (BGs) of brine waste and 12.8 BGs of freshwater required in OH. Put another way…
233.9 MGs is equivalent to the annual waste production of 5.2 million Ohioans – or 45% of the state’s current population.
Due to the low costs incurred by industry when they choose to dispose of their fracking waste in OH, drillers will have only to incur $100 million over the next five years to pay for the injection of the above 1.0 BGs of brine. Ohioans, however, will pay at least $1.5 billion in the same time period to dispose of their municipal solid waste. The average fee to dispose of every ton of waste is $32, which means that the $100 million figure is at the very least $33.5 million – and as much as $250.6 million – less than we should expect industry should be paying to offset the costs.
Environmental Accounting
In summary, there are two ways to look at the potential “energy revolution” that is shale gas:
Using the same traditional supply-side economics metrics we have used in the past (e.g., globalization, Efficient Market Hypothesis, Trickle Down Economics, Bubbles Don’t Exist) to socialize long-term externalities and privatize short-term windfall profits, or
We can begin to incorporate into the national dialogue issues pertaining to watershed resilience, ecosystem services, and the more nuanced valuation of our ecosystems via Ecological Economics.
The latter will require a more real-time and granular understanding of water resource utilization and fracking waste production at the watershed and regional scale, especially as it relates to headline production and the often-trumpeted job generating numbers.
We hope to shed further light on this new “environmental accounting” as it relates to more thorough and responsible energy development policy at the state, federal, and global levels. The life cycle costs of shale gas drilling have all too often been ignored and can’t be if we are to generate the types of energy our country demands while also stewarding our ecosystems. As Mark Twain is reported to have said “Whiskey is for drinking; water is for fighting over.” In order to avoid such a battle over the water-energy nexus in the long run it is imperative that we price in the shale gas industry’s water-use footprint in the near term. As we have demonstrated so far with this series this issue is far from settled here in OH and as they say so goes Ohio so goes the nation!
A Moving Target
Figure 6. ODNR projection map of potential Utica productivity from spring 2012
OH’s Department of Natural Resources (ODNR) originally claimed a big red – and nearly continuous – blob of Utica productivity existed. The projection originally stretched from Ashtabula and Trumbull counties south-southwest to Tuscarawas, Guernsey, and Coshocton along the Appalachian Plateau (See Figure 6).
However, our analysis demonstrates that (Figures 7 and 8):
This is a rapidly moving target,
The big red blob isn’t as big – or continuous – as once projected, and
It might not even include many of the counties once thought to be the heart of the OH Utica shale play.
This last point is important because counties, families, investors, and outside interests were developing investment and/or savings strategies based on this map and a 30+ year timeframe – neither of which may be even remotely close according to our model.

Footnotes
$4.25 per 1,000 gallons, which is the current going rate for freshwater at OH’s MWCD New Philadelphia headquarters, is 4.7-8.2 times less than residential water costs at the city level according to Global Water Intelligence.
Carroll County wells have seen days in production jump from 36-62 days in 2011-2012 to 68-78 in 2014 across 256 producing wells as of Q2-2014.
One Mcf is a unit of measurement for natural gas referring to 1,000 cubic feet, which is approximately enough gas to run an American household (e.g. heat, water heater, cooking) for four days.
Assuming average oil and natural gas prices of $96 per barrel and $8.67 per Mcf during the current period of production (2011 to Q2-2014), respectively
On a per-API# basis or even regional basis we have not found drilling muds data. We do have it – and are in the process of making sense of it – at the Solid Waste District level.

When the unconventional oil and gas extraction boom hit Pennsylvania in the mid-2000s small, local operators were among the first on the scene. As shale plays continued to develop, many of these smaller companies were bought out by larger, national corporations. Larger oil and gas development companies often maintain that they are better able to handle the expected regulatory requirements, and so FracTracker wanted to determine if there was a change in the compliance record for wells that changed hands. Does having more resources available to them translate into stronger compliance standards for oil and gas drillers, better training for their employees, and a greater burden to get things right? Investigating these questions by looking into compliance data and the sale of wells, however, was no easy task.
Analysis Methods
There are no indications in either the drilled wells or permits datasets available from the DEP that a well has changed hands; in both of these sources, one operator’s name is simply substituted for the other. It is possible to comb through old news stories, and find that East Resources sold its assets to Shell in 2010, for example. However, this approach is piecemeal, and would not lead to satisfactory results on an industry-wide analysis.
Major obstacles to our analysis included:
Lack of information on the transfer of oil and gas wells from one operator to another
There is often a lag time between the time violations occur and when they are reported
Errors in compliance reporting. For example, one API Number was found to have the operator listed as “Not Assigned” (It was later discovered that this well was never sold).
Results
Unlike wells and permits, any items on the compliance dataset are attributed to whichever company was operating the well at the time the violation was issued. So while FracTracker could not do the analysis that we wanted to because of the limitations of available data, we were able to isolate 30 wells that have changed hands between January 1, 2000 and November 4, 2014 (Table 1). One well has been bought and sold twice, with each of the three operators being issued violations.
In some instances the original well owner was reported to be out of compliance more times than the second owner. For example, API Number 013-20012 had 11 violations reported under its first owner and only 1 since it has been sold. The contrary also occurred, however, such as in the case of API Number 065-26481, which had 4 violations reported under its first owner and 14 under its second owner. There are not enough data points to determine which scenario is the trend in the data – if in fact there is one.
Due to limitations in the data, we cannot currently evaluate whether the notion that larger companies can improve the track record of problematic wells. In fact, many of the wells that were issued violations for multiple operators really just changed hands from one big operator who wanted to get out of the Marcellus to another big operator who wanted to get in. Our small sample doesn’t include any of the wells that were issued violations to only one company, of all the wells that changed hands over the years. To accurately assess the scenario, more data would have to be released, specifically the date when wells changed hands from one company to another.

One of the potentially troubling aspects of oil and gas development is that there are usually people who live in the vicinity of the wells. Pennsylvania now has over 8,000 active unconventional wells; there are any number of issues that can occur with these modern, industrial-scale sites, including road degradation, contaminated water, and health impacts, among others. In addition, there are over 93,000 of the smaller, conventional wells in operation throughout the Commonwealth. While these garner far less attention than their unconventional counterparts, they are also prone to producing similar impacts, not to mention that since many of them are older wells, they not only have potentially been subject to deterioration and occasional neglect, but were constructed during a period with less stringent requirements than are currently expected.
Petroleum engineers are now capable of drilling horizontally for tens of thousands of feet. For the most part, however, this technology is employed to maximize production, rather than to ameliorate impacts on people who live near the product. But who are these people? To help to answer this question, the FracTracker Alliance calculated the number of people living in a half-mile radius around active wells in the state.
More than 1.2 million Pennsylvanians live within the impact area.
Of the 93,754 wells that have been drilled in the state since 1950 that have not yet been plugged, the Pennsylvania DEP only has location data for 79,118 of them. All but one of the 14,636 missing locations are for wells that are categorized as Conventional. While one must presume that there is some overlap in coverage within the half-mile zone, the extent of this region – and therefore the population that lives within it – cannot be determined.

To maximize the reliability of our calculations, this map was created using a custom Albers equal-area projection centered on Pennsylvania. A half-mile buffer around each well type was created, and the resulting layer was clipped to Census tract data. The ratio of the smaller clipped area to the full Census tract area was calculated, and that ratio was then multiplied by the population totals from the 2010 Census to obtain our population estimates of the half-mile zone. The area in the study area is larger than six states, while the calculated population is larger than that of eight states.
Fig. 2. Number of people in PA near oil and gas wells (79,118 active wells for which location data are available). Note that some regions are with a half-mile of both conventional and unconventional wells.
The county most impacted, in terms of area, for unconventional wells is Bradford, with 353 square miles (See Figure 2). Washington County had the most people living in the zone, however, with 20,566. For conventional wells, the drilling landscape is the largest in Indiana County, affecting 761 square miles, while Erie County has the most people in the half-mile zone, with 212,900. When considering all wells together, the numbers are almost identical to conventional wells. Indiana County leads with 762 square miles, while the drill zone in Erie County represents 211,903 people, or 76% of the county’s population in 2010.

Recently, I was observing how Statoil was managing their gas well traffic, how well it was moving, and whether local residential traffic was being significantly delayed.
Figure 1. Road map referred to throughout text
In Wetzel County, WV, gas trucks travel 4.5 miles from a Statoil pipe yard (Fig 1. Location A) in Uniontown to the Statoil Kuhn well pad (E). This trip can take at least 15 minutes for each truck. Rockford is also doing pipeline work along this route (B and D).
The roadway Statoil is using, even though it is small gravel lane, is a public route. Routine well pad traffic was moving between the pad and pipe yard. When I attempted to travel out to the well pad, I noticed some issues around the pipeline crossing. A large truck was blocking the road and all traffic was stopped. At 3:59 pm, a large dump truck hauling drill cuttings left the well pad coming towards the pipeline. Statoil personnel radioed the flagger at the pipe yard to stop traffic there.
The dump truck was stopped at the pipeline crossing, point D at 4:09 pm, where the road was blocked. It was not until 4:34 pm that traffic was finally able to proceed. This section of road was closed for 35 minutes, as was the lower road at the pipe yard.
For the past few days, Statoil has been stopping all traffic as soon as any truck leaves the well pad, whether the pipeliners have the road blocked or not.
Associated Issues
There are three serious factors that significantly hamper traffic flow along this route:
Statoil’s Kugh Well Pad
Statoil has flagger-radio personnel stationed at the pipe yard and at the pad, but not at the top of the hill (C) about a mile from the pipe yard. As a result, there was no way to allow any local traffic to come up the hill even when they intend to continue heading west or southeast. With a flagger-radio at the top of the hill, local traffic could be up the hill and long gone before any large trucks got to there. (Note: After a few weeks a traffic person was then stationed at the top of the hill).
Not all Statoil subcontractors trucks are equipped with CB radios, so it is impossible to track their progress or location on this road.
Rockford and Statoil do not use any common radio band. They do not appear to communicate with each other even though they are working along this same truck route.
This traffic block incident luckily did not include emergency vehicle traffic. If there had been any accident on or near the well pad or the pipeline right of way, no one would have been able to get through. It would seem that it is in the best interest of the companies and their employees to make sure the road is clear, all the time. When I discussed this with the tool pusher* on the well pad, he agreed. He was also concerned that there was no helicopter landing area nearby in the event of a serious accident. He runs a safe well drilling operation but wanted to be certain that an emergency vehicle could get through.
* A tool pusher is the boss man who runs the whole drilling operation as a subcontractor to the gas operator.
OH Utica Production, Water Usage, and Changes in Lateral Length
Part I of a Multi-part Series By Ted Auch, OH Program Coordinator, FracTracker Alliance
As shale gas expands in Ohio, how too does water use? We conducted an analysis of 500+ Utica wells in an effort to better understand the water-energy nexus in Ohio between production, water usage, and lateral length across 500+ Utica wells. The following is a list of the primary findings from this analysis:
Lateral Length
Figure 1. Modified EIA schematic highlighting the lateral portion of the unconventional well
In unconventional oil and gas drilling, often operators need to drill both vertically and then laterally to follow the formation underground. This process increases the amount of shale that the well contacts (see the modified EIA schematic in Figure 1). As a general rule Ohio’s Utica wells transition to the horizontal or lateral phase at around 6,800 feet below the earth’s surface.
1. The average Utica lateral is increasing in length by 51-55 feet per quarter, up from an average of 6,369 feet between Q3-2010 and Q2-2011 to 6,872 feet in the last four quarters. Companies’ lateral length growth varies, for example:
Gulfport is increasing by 46 feet (+67,206 gallons of water),
R.E. Gas Development and Antero 92 feet (+134,412 gallons of water), and
Chesapeake 28 feet (+40,908 gallons of water).
2. An increase in lateral length accounts for 40% of the increase in the water usage, as we have discussed in the past.
3. As a general rule, every foot increase in lateral length equates to an increase of 1,461 gallons of freshwater.
Regional and County-Level Trends
This section looks into big picture of shale gas drilling in OH. Herein we summarize the current state of water usage by the Utica shale industry relative to hydrocarbon production, as a percentage of residential water usage, as well as long-term water usage and waste production forecasts.
1. Freshwater Use
Across 516 wells, we found that the average OH Utica well utilizes 5.04-5.69 million gallons of freshwater per well.
This figure includes a ratio of 12:1 freshwater to recycled water used on site.
Water usage is increasing by 221-330,000 gallons per well per quarter.
Note: In neighboring – and highly OH freshwater reliant-West Virginia, the average Marcellus well uses 6.1-6.6 million gallons per well, with a trend increase of 189-353,000 gallons per quarter per well.
Water usage is up from 4.88 million gallons per well between 2010 and the summer of 2011 to 7.27 million gallons today.
Over the next five years, we will likely see 18.5 billion gallons of freshwater used for shale gas drilling in OH.
On average, drilling companies use 588 gallons of water to get a gallon of oil.
Average: 338 gallons of water required to get 1 MCF of gas
Average: 0.078 gallons of brine produced per gallon of water
2. Residential Water Allocation
A portion of residential water (3.8-6.1% of usage) is being allocated to the Utica drilling boom.
This figure is as high as 81% of residential water requirements in Carroll County.
And amounts to 2.2-3.5% of the available water in the Muskingum River Watershed.
The allocation will increase over time to amount to 8.2-10.5% of residential usage or 4.4-5.6% of Muskingum River available water.
3. Permitted Wells Potential
If all permitted Utica wells were to come online (active), we could expect 299.7 million gallons of additional brine to be produced and an additional 220 million gallons of freshwater a year to be used.
This trend amounts to 1.1 billion gallons of fracking brine waste looking for a home within 5 years.
4. Waste Disposal
Stallion Oilfield Services has recently purchased several Class II Injection wells in Portage County.
These waste disposal sites are increasing their intake at a rate of 2.13 million gallons per quarter, 4.76 times that of the rest of OH Class II wells.
Water Usage By Company
The data trends we have reviewed vary significantly depending on the company that is assessed. Below we summarize the current state of water usage by the major players in Ohio’s Utica shale industry relative to hydrocarbon production.
1. Overall Statistics
The 15 biggest Water-To-Oil offenders are currently averaging 16,844 Gallons of Water per gallon of oil (PGO) (i.e., Shugert 2-12H, Salem-Grubbs 1H, Stutzman 1 and 3-14H, etc).
Removing the above 15 brings the Water-To-Oil ratio down from 588 to 52 gallons of water PGO.
The 9 biggest Water-To-Gas offenders are currently averaging 16,699 gallons of water per MCF of gas.
Removing the above 9 brings the Water-To-Gas ratio down from 338 to 27 gallons of water per MCF of gas.
Company differences are noticeable (Figure 2):
Figure 2. Average Freshwater Use Among OH Utica Operators
Antero and Anadarko used an average of 9.5 and 8.8 MGs of water per well during the course of the 45-60 drilling process, respectively (Note: HG Energy has the wells with the highest water usage but a limited sample size, with 9.8 MGs per well).
Six companies average in the middle with 6.7-8.1 MGs of water per well.
Four companies average 5 MGs per well, including Chesapeake the biggest player here in OH.
Devon Energy is the one firm using less than 3 MGs of freshwater for each well it drills.
2. Water-to-Oil Ratios
Figure 3. Water-to-Oil Ratios Among OH Utica Operators
Freshwater usage is increasing by 3.6 gallons per gallon of oil. Companies vary less in this metric, except for Gulfport (Figure 3):
Gulfport is by far the least efficient user of freshwater with respect to oil production, averaging 3,339 gallons of water to extract one gallon of oil.
Intermediate firms include American Energy and Hess, which required 661 and 842 gallons of freshwater to produce a gallon of oil.
The remaining eleven firms used anywhere from 6 (Atlas Noble) to 130 (Chesapeake) gallons of freshwater to get a unit of oil.
3. Water-to-Gas Ratios (Figure 4)
Figure 4. Water-to-Gas Ratio Among OH Utica Operators
American Energy is also quite inefficient when it comes to natural gas production utilizing >2,200 gallons of freshwater per MCF of natural gas produced
Chesapeake and CNX rank a distant second, requiring 437 and 582 gallons of freshwater per MCF of natural gas, respectively.
The remaining firms for which we have data are using anywhere from 13 (RE Gas) to 81 (Gulfport) gallons of freshwater per MCF of natural gas.
4. Brine Production (Figure 5)
Figure 5. Brine-to-Oil Ratios among Ohio Utica Operators
With respect to the relationship between hydrocarbon and waste generation, we see that no firm can match Oklahoma City-based Gulfport’s inefficiencies with an average of 2,400+ gallons of brine produced per gallon of oil.
American Energy and Hess are not as wasteful, but they are the only other firms generating more than 750 gallons brine waste per unit of oil.
Houston-based Halcon and OH’s primary Utica player Chesapeake Energy are generating slightly more than 400 gallons of brine per gallon of oil.
The remaining firms are generating between 17 (Atlas Noble and RE Gas) and 160 (Anadarko) gallons of brine per unit of oil.
Part II of the Series
In the next part of this series we will look into inter-county differences as they relate to water use, production, and lateral length. Additionally, we will also examine how the OH DNR’s initial Utica projections differ dramatically from the current state of affairs.
