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

Cimarex has implemented spill prevention protocols to reduce the occurrence of spills and protect the local species in the areas in which we operate. We respond quickly to any spill, mitigate its potential impact and communicate with any federal and state agencies as necessary.

In 2019, Cimarex had 86 total reportable spills, up slightly from our 80 reportable spills in 2018. Eighty-one percent (81%) of the reported 2019 spills released less than 100 barrels per occurrence. Of the total 86 spills in 2019, 64% occurred in containment. Sixty-seven percent (67%) of the reported produced water releases occurred in containment with a recovery rate of 95%. Spilled hydrocarbon volumes represented 0.0012% of company hydrocarbon equivalents production and produced water spill volumes represented 0.0019% of company water production.

Spill Intensity Rate1 2017 2018 2019
Hydrocarbon 0.0003% 0.0005% 0.0012%
Produced Water 0.0176% 0.0015% 0.0019%
Spill Recovery Rate2
Hydrocarbon 52.7% 59.3% 75.1%
Produced Water 7.1% 70.0% 82.1%

1Intensity rate is defined as total product spilled divided by gross product produced

2Recovery rate is defined as recovered product divided by total product spilled

Constructed lined containment system

The data provided in the table above and charts only represent data required to be reported to regulatory authorities. Cimarex internally reviews every spill regardless of product type, spill size or regulatory requirements. Internal reviews not only promote employee awareness of the importance of spill prevention, but helps us to undertake proactive measures to minimize and eliminate future occurrences.

One way Cimarex minimizes spill impacts is by using one of two containment types: a constructed and lined containment system or a fully enclosed berm to capture releases within the contained area. The containment design of each facility incorporates industry best practices, complies with federal regulations, and considers the facility's proximity to sensitive areas, such as nearby water sources.

Temporary lined containment for completion operations

During completion operations, Cimarex utilizes 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 is transported to the wellsite through a temporary on-demand pipeline system, avoiding potential produced water spills from leaks in liners associated with surface containment pits. More detailed information can be found on our water resource management page.

Cimarex is committed to ensuring the 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 remove potentially corrosive liquids from the pipeline and testing to evaluate the pipeline metal.

*Reporting requirements for produced water not outlined in Texas Administrative code - XEC best practice is to make a courtesy call for spills ≥ 100 bbls to the RRC

Note: Other includes drilling mud, diesel fuels, and chemicals
