Movement of Pennsylvania’s non Marcellus Waste 2010

One of the biggest concerns about the Marcellus Shale industry in Pennsylvania is how to deal with all of the waste products that are created in the drilling, stimulation, and production of the wells. There are also more than 40,000 oil and gas wells from other formations in the Commonwealth that reported waste production to the Pennsylvania Department of Environmental Protection (DEP) last year. Whether this waste ultimately found itself into publicly owned treatment works, industrial waste treatment facilities, injection wells, or spread on roadways, it almost always has to be shipped to a different location, sometimes hundreds of miles away.

For more information on specific facilities that accepted non Marcellus waste in 2010, click on one of the maps below, then use our information tool (“i” icon) and click on any map icon.

Brine

Yellow dots indicate wells that reported brine production, and red squares are receiving facilities. The green lines are the paths that the waste takes, as the crow flies. Darker lines indicate larger quantities of brine, which are measured in barrels. For more information on specific features, please click the map for a zoomable, dynamic view.

Statewide, almost 4.5 million barrels of brine was produced by non Marcellus Shale wells in 2010, which was transported over 900,000 miles as the crow flies(1) from the various wells to the facility locations, with an average one way trip of about 30 miles.

Drill Cuttings

Only one operator reported drill cutting waste from a total of three wells. All of this type of waste went to the same facility. Geographic coordinates were not included for the receiving facility in the data, so mapping and distance measurements were not performed for this analysis. Suffice it to say, however, that the amounts discussed are relatively small compared to brine and other types of waste.

Drilling Fluid

The color scheme for this map similar to that of brine, above, but in this view, yellow dots indicate wells producing drilling fluid waste.

More than 300,000 barrels of drilling fluid was produced last year from non Marcellus Shale wells in Pennsylvania. That waste traveled over 18,500 miles as the crow flies en route to its receiving facilities.

Frac Fluid

The color scheme for this map similar to that of brine, above, but in this view, yellow dots indicate wells producing frac fluid waste.

While the term “frac fluid” is often used to refer to the chemical additives that are used along with water and sand to hydraulically fracture a well, in terms of the waste report, it refers to the flowback water. This type of waste contains the other type of frac fluid, but at significantly reduced quantities.

Last year, non Marcellus Shale wells reported producing over 499,000 barrels of frac fluid waste, which traveled almost 82,000 linear miles to receiving facilities, with the average one way trip being about 40 miles in length.

1. Please note, for each distance analysis, only wells from the waste production report which included decimal degree data for both the wells and receiving facilities were included. Therefore, the distances are being understated. For example, only about 29,500 of the more than 40,500 non Marcellus wells that produced brine last year are included in this figure, or about 73 percent.
