Chaparral Energy

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, 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.

STACKed Plays That Pay Off


The STACK Play in central Oklahoma is home to several oil and gas formations that sit stacked atop one another. These formation layers are vertically stacked hundreds to even thousands of feet on top of each other, creating overlapping layers known as “stacked pays.”

Stacked pays allow operators, such as Chaparral, access to drill multiple formations from a single surface location, providing excellent cost efficiencies, improved oil and gas recoveries and an overall smaller surface footprint.

Exploration & Production

The geographic area referred to as the STACK is located primarily below portions of Canadian, Kingfisher and Garfield counties in central Oklahoma. This area is home to multiple oil-rich reservoirs that are stacked vertically, including the Meramec, Osage and Woodford formations.

This stacking of plays allows Chaparral to effectively recover oil and gas from multiple formations using pad drilling, well spacing techniques and other operational efficiencies, which result in significant cost savings, reduced environmental impacts and extremely profitable operations.

The Meramec and Osage intervals of the Mississippian are two of the deeper oil-saturated reservoirs found just above the Woodford formation.

To date, Meramec development has centered primarily in Oklahoma’s Kingfisher, Blaine and Canadian counties.

The Woodford Shale is the key hydrocarbon source for STACK reservoirs and is also an attractive drilling target itself.

The formation has been the source for multiple productive regions including the STACK, SCOOP, Merge and other areas within the Arkoma Basin.

Chaparral has additional E&P operations in Oklahoma and the Texas Panhandle in the Miss Lime and Marmaton plays. These legacy assets continue to provide steady production and cash flow.
