Cimarex is proud to be a responsible driller and producer of oil and gas. We believe that minimizing the environmental impact of our operations is an important part of how we conduct ourselves and that the impact of our activities should be minimal and temporary. We want to leave things as we found them.
We strive to keep our operational footprint small. In the Cana field we are able to minimize surface disturbance by utilizing multi-well pad drilling. This technique allows multiple horizontal wells to be drilled from a single location. These wells are able to reach and extract hydrocarbons over an area that would have traditionally required much greater surface disturbance. Other benefits of pad drilling include less truck traffic, consolidated storage tanks and facilities and more efficient field management.
In February 2011 Cimarex began reporting, by well, all of our hydraulic fracturing activities to FracFocus. FracFocus is the national hydraulic fracturing chemical registry managed by the Ground Water Protection Council and Interstate Oil and Gas Compact Commission.

Cimarex began reporting Greenhouse Gas Emissions to the EPA in 2011.
Beginning January 1, 2015, the EPA will require that all operators use a completion combustion device to flare or capture gas produced during the completion of its wells. Aimed at reducing methane emissions and known as green completions, Cimarex already complies with the EPA’s standards. Gas that might previously have been released into the atmosphere is now being properly flared or captured at the wellhead and used as fuel or sold.

Water recycling is another area of focus. Typically frac flow-back fluids, which are composed mostly of water, are disposed of as a waste product. We are changing that practice and recycling water wherever we can. In the Cana field we utilize large portable storage tanks to reuse frac flow-back fluids for hydraulic fracturing of new wells. Similarly, we recycle produced water in the Permian Basin where the produced water contains high salt levels, often requiring special disposal wells. We are installing a recycling facility in 2013 in Culberson County, Texas that initially will desalinize 5,000 barrels of produced water per day with plans to increase capacity in the near future. Both the resulting water and the heavy brine (leftover salt from the desalinization) will be used for future fracture stimulation activities. Not only do the Cana and Permian water recycling projects save water, but they also reduce truck traffic on limited roads.
