Corporate Responsibility

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

Hydraulic Fracturing

Hydraulic fracturing, often referred to as fracing, is an essential part of our business and is applied to nearly all of our new oil and natural gas wells. Hydraulic fracturing is the process of injecting a pressurized fluid, comprised mainly of water and sand, into a formation to create a network of linked fractures that allow oil and gas in the formation to flow into the well casing and surface gathering lines.

During this process, Cimarex is focused on wellbore integrity, protecting local aquifers with steel casing and cement, minimizing chemical usage and using environmentally friendly chemicals available.

Wellbore integrity

While fresh water aquifers are protected from oil and gas operations by thousands of feet of rock barrier, wellbore integrity is critical to ensure groundwater protection. Cimarex utilizes multiple layers of steel casing and cement to ensure aquifers are isolated from operations. During drilling and completion operations, we continuously monitor a well’s pressure to ensure wellbore integrity remains intact. Monitoring of the wellbore pressure continues throughout the life of the well.

Chemical Usage

Cimarex has been an active participant in fracfocus.org since 2012 with over 800 individual well completions reported to the organization to date. FracFocus is the national hydraulic fracturing chemical registry managed by the Ground Water Protection Council and Interstate Oil and Gas Compact Commission. A variety of information can be found in this registry, including chemical usage and the purpose of each chemical.

Cimarex continually evaluates the type and volume of chemicals used in its operations with a focus on reducing the chemicals used and utilizing environmentally friendly chemicals. The chemicals used in a typical well completion represent less than 0.1% of the total fluid composition. Cimarex does not use diesel fuels or BTEX (benzene, toluene, ethylbenzene and xylene) in any of its completions operations.

Sampling

Cimarex began taking soil and water samples at its well sites in 2012. Sampling is performed prior to operations to provide a baseline of the water and soil quality. In particular, the baseline allows us to identify any incremental impact of our operations on levels of certain salts, radioactive elements, metals and chemicals in the water or soil. In circumstances where we need to perform reclamation on a site, we will use this data as a reference to the condition of the property prior to our operations. A copy of the sampling report is provided to the property owners.
