Hydraulic Fracturing

Seneca Resources contractors checking equipment during a hydraulic fracturing job.
The process called hydraulic fracturing or "hydrofracing," involves pumping water mixed with sand and a very minimal amount of chemicals into the well at a very high pressure to fracture the formation and allow the natural gas to flow freely.

Once the fracturing process is completed, Seneca removes fluids from the well and recycles the water and chemical mixture, (referred to as "frac fluid"), to use in other well operations. Any frac fluid that is not recycled is treated. Seneca's goal is to recycle 100 percent of all frac fluid, resulting in zero discharge in its operations.

Seneca Resources is committed to being best in class, employing best practices in its operations and being a good steward of the environment. Evidence of this commitment is Seneca's water usage policies as well as its frac fluid recycling program.

When feasible, Seneca Resources has used coal mine drainage water verses fresh water as part of its drilling and completion operations - the longest continuous program of its kind in the Pennsylvania Marcellus.


Hydraulic Fracture Fluid Components


Seneca voluntarily posts data related to the components it utilizes in its hydraulic fracturing operations on the chemical registry website created by the Ground Water Protection Council and the Interstate Oil and Gas Compact Commission. This site contains detailed information about the hydraulic fracturing process and a listing on a well-by-well basis specifying the contents of hydraulic fracturing fluids used at each location. The website is accessible via: www.fracfocus.org.
