Drilling Chemicals

The information here is based on chemicals used in drilling a natural gas well, Crosby 25-3, in Park County, Wyoming. Natural gas, petroleum condensate, and drilling fluids were accidentally released from the ground adjacent to the well due to a breach in the surface casing.

Fracturing Chemicals

Fracturing, frac’ing, and stimulation are terms used to describe a process commonly used to facilitate the release of natural gas and to improve production. In this process, depending on the geology of the region, as much as one million gallons of fluid or more are injected underground under extremely high pressure to open up fractures in the strata being mined. The fluids used in this process are composed of water and a variety of chemicals.
