Saline/Brine Water
Injection Wells – Class IIClass II wells inject fluids associated with oil and natural gas production.Most of the injected fluid is salt water (brine), which is brought to the surfacein the process of producing (extracting) oil and gas.
Regulated by:EPA - http://www.epa.gov/safewater/uic/wells_class2.htmlhttp://www.epa.gov/safewater/uic/wells_class2.html
Does the UIC Program regulate hydraulic fracturing?Sometimes. The UIC Program regulates the following activities: Well injection of fluids into a formation to enhance oil and gas
production (Class II wells). Fracturing used in connection with Class II and Class V injection
wells to “stimulate” (open pore space in a formation). Hydraulic fracturing to produce methane from coal beds in Alabama.
Note: Class V wells are shallow wells that inject water into or above a freshwater aquifer. http://www.epa.gov/ogwdw000/uic/

Active Marcellus Production Site – Frac Fluid Chemistry
Typically Frac Water is comprised of clean water with a low probably for scale formation, but treated effluents and other sources being evaluated. The components include:
Friction Reducer – anionic polymer high molecular weight(hold frac sand and other particles)
Wetting Agent- nonionic surfactant – reduce surface tension and improvefrac water flowback.
Biocides- control growth or regrowth of microorganisms.
Scale Inhibitor – phosphate based chemicals to inhibit precipitate formation and scale formation.

Flowback Water Chemistry
