That core value is reflected in a simple fact: safety is not a thing we do; it is the way we do everything. Spills and injuries are known risks in the oil and gas industry, and are avoidable when appropriate precautions are taken. For Chaparral, avoidance comes from a culture that is both comprehensive and reflects our zero-incident mindset. We operate every phase of our business cleanly and safely – from before wells are drilled and employees are hired to after wells are decommissioned and people retire. The planning that is required by that high standard also contributes to our efficiency, making us not just a safer enterprise but a more profitable one. Chaparral teams with ISNetworld to implement an enhanced screening and requirement process to ensure our vendors follow the necessary processes and safety procedures. These extensive efforts ensure not only the safety of our employees and facilities, but also that of the contractors working on our locations and the communities that surround them.

MAIN MENU ABOUT US OPERATIONS ESG INVESTORS OWNERS SECONDARY MENU EH&S CAREERS CONTACT US Operations Energizing America’s Heartland Chaparral leverages our expertise and low-cost structure to unlock reservoirs deep beneath the earth’s surface. Focused primarily on our leasehold in the oil window of the Anadarko Basin, with liquids yielding approximately 60% of total production, our core acreage position provides access to the Meramec, Osage and Woodford formations. Producing these resources, however, requires highly trained experts. Our talented employees have the knowledge and expertise needed to decipher each formation’s unique geologic and productive characteristics as we continue to find innovative, cost-efficient ways to recover these previously untapped oil and gas deposits.
