Chaparral Energy

Energizing America’s Heartland

Chaparral leverages our expertise and low-cost structure to unlock reservoirs deep beneath Oklahoma's historic, oil-rich landscape.

Focused primarily on our leasehold in Oklahoma’s fast-growing STACK Play, we are creating significant economic and shareholder value. Our more than 129,000 STACK acres provide access to the Meramec, Osage and Woodford formations — a robust inventory that will fuel our company for decades to come.

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 highly economical 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 location. With the ability to drill multiple horizontal wells from a single vertical wellbore, the STACK provides excellent cost efficiencies, improved oil and gas recoveries and an overall smaller surface footprint.

Chaparral has approximately 129,000 net surface acres with stacked-pay potential in the Meramec, Osage, Woodford and Hunton formations.


Exploration & Production

The geographic area referred to as the STACK is located primarily below portions of Blaine, Canadian, Garfield, Kingfisher and Major 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.  

Key Facts:

  • Net Acres: 129,000+
  • Daily YTD Q3 2019 Production: ~20,500 Boe/d

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. Activity is, however, increasing in Garfield, Major and Dewey counties as STACK operators, such as Chaparral, continue to expand the boundaries of the lucrative STACK Play.

The Woodford Shale is the key hydrocarbon source for several productive regions across Oklahoma, including the STACK 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. The Woodford continues to be one of Oklahoma’s most active and historically prolific formations.
