Corporate Responsibility

Our approach is to analyze every project individually to determine its economic, safety and environmental impacts over the life of the project

Water Resource Management


XEC engineered riser for water reuse access

Efficient water management is a key focus for Cimarex. Not only are substantial water volumes required for hydraulic fracing operations, but the wells we complete can produce large volumes of water which need to be safely disposed. Cimarex has reduced its fresh water needs for Permian hydraulic fracing operations by utilizing an on-demand pipeline system tied into our existing saltwater gathering and disposal infrastructure to provide frac source water. 


In 2018, 52% of our Permian hydraulic fracturing water needs were met by recycling water volumes from our operated wells. With the on-demand system described above we are able to direct water to a completion site, treatment free, for use in hydraulic fracturing operations. This not only minimizes the need for fresh water but reduces water volumes injected into saltwater disposal (SWD) wells. When additional water volumes are required for completion operations, we source brackish water, leaving freshwater as a last resort. Produced water that is not re-used is primarily injected into SWD wells that we own and operate. Forecasted produced water rates for full-field development and seismicity potential are considered when determining the location and underground formation for our SWD wells. We also review the Environmental, Safety and Health (ESH) programs of third-party operators of SWD wells that dispose of our produced water to ensure they are operating at a high standard.

In the Mid-Continent region, water for fracing operations is primarily sourced from local rivers. We continually assess community needs for water versus industry demand. If community constraints are forecasted, we are prepared to move to alternative water sources. Our oil and gas wells in the Mid-Continent region produce significantly lower volumes of water than in the Permian Basin, the bulk of which is associated with completion operations. As a result, the water production from our Mid-Continent wells is short-lived and is piped or trucked to SWD systems, most of which we operate. Any third-party operators are vetted to ensure they are operating at a high standard.

*Intensity rate is defined as total water sourced divided by total estimated energy recovered. Total estimated energy recovered is the most current estimated reserves of wells completed during that respective year multiplied by a BTU factor. Changes to prior years reflect any adjustments resulting from changes in estimated reserves compared to prior year estimates.
