Corporate Responsibility

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

Spill Prevention

Our spill prevention programs reduce the occurrence of spills and protect the local species in the areas in which we operate. Cimarex has processes in place to respond quickly and effectively to a spill and to mitigate its impact.

In 2017, Cimarex reduced the total number of its reportable spills (or releases) by 56% from 2016, and total hydrocarbon volume was reduced by 89%. Of the reported hydrocarbon and produced water spills in 2017, 79% were releases involving 100 barrels or less of hydrocarbon and/or produced water spilled. For reference, 100 barrels is equivalent to about half the volume of a typical semi-truck gasoline tanker you might see on the highway. Hydrocarbon spilled volumes represented 0.000% of total hydrocarbon production, and produced water spilled volumes represented 0.018% of total produced water production.

Spill Intensity Rate* 2015 2016 2017
Hydrocarbon 0.004% 0.003% 0.000%
Produced Water 0.008% 0.006% 0.018%

*Intensity rate is defined as total product spilled divided by gross product produced

In August 2017, during a severe rainstorm and resulting power outages, a transmission line on a Cimarex operated salt water disposal (SWD) system in Culberson County, Texas ruptured releasing approximately 18,000 barrels of produced water. Cimarex immediately notified federal and State agencies of the release and mobilized its Emergency Response team to respond to the release. The response included deployment of hard and absorbent booms at various locations along the Delaware River to contain any constituents associated with the release from migrating downstream, monitoring and sampling of water flow along the river and remediation of areas impacted by the release. Remediation was completed in the first quarter of 2018 and no immediate contamination or impact was identified in the area. Cimarex intends to fund a water monitoring project in the area for at least three years. Based on the results of a third party detailed hazard analysis of this and other Cimarex operated SWD systems, Cimarex is working diligently to complete identified action items to reduce the likelihood of a similar event. Cimarex also has taken multiple steps to minimize the chance of a similar event occurring in any of our SWD systems or other operations.

The data provided in the table and charts only represent data required to be reported to regulatory authorities. In order to improve our processes, Cimarex made the decision to internally review every spill no matter the product or spill size or regardless of whether it is required to be reported to regulatory authorities. Internal reviews also raise employee awareness of the importance of spill prevention.

One way Cimarex minimizes the impact of a spill is through containment. Every Cimarex production facility has one of two types of containment: a constructed and lined containment system or a fully enclosed berm to capture releases within that contained area. The containment design of every facility incorporates industry best practices and considers the facility's proximity to sensitive areas, such as nearby water sources.

During completion operations, Cimarex uses temporary lined containment around all fracing chemicals, fluid tanks and blending equipment. Surface containment pits, which are used for storing water prior to completion operations, are used for fresh water only. Any produced water used in completion operations comes to the wellsite through a temporary on-demand pipeline system, avoiding potential produced water spills from leaks in liners at surface containment pits. More detailed information can be found on our water resource management page.

Cimarex is committed to ensuring integrity of our operated oil and gas gathering systems to minimize the potential for leaks. Elements of the program include the use of corrosion protection, systematic pigging to sweep potentially corrosive liquids out of the pipeline and non-destructive testing to evaluate the properties of the pipeline metal, including wall thickness.
