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 119,000 STACK acres provide access to the Oswego, 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 up to 16 separate 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 119,000 net surface acres with stacked-pay potential in the Oswego, Meramec, Osage, Woodford and Hunton formations.

Our Focus

Exploration & Production

Select a Section
an image of operation exploration & production STACK

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 Oswego, Meramec, Osage, Woodford and Hunton 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: 119,000
  • Potential Recovery: More than 900 MMBoe
  • Daily Q2 2018 Production: 13,198 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.

Chaparral has a significant leasehold position in the Oswego. Historically a vertical target, horizontal drilling and hydraulic fracturing technologies are unlocking previously unrecovered reserves of this mid-Pennsylvania-age carbonate play.

Our first horizontal Oswego well was drilled in 2013 and is expected to produce more than 1.5 million barrels of oil equivalent during its lifetime. We have since drilled or participated in 55 wells in the Oswego within the STACK region, with an initial 30-day production rate of almost 500 Boe/d, of which approximately 90 percent is oil. At vertical depths of only 6,000 to 7,000 feet, the Oswego yields extremely attractive economic results.

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 and areas within the Arkoma Basin. The Woodford continues to be one of Oklahoma’s most active and historically prolific formations.

Chaparral has additional E&P operations in Oklahoma and the Texas Panhandle in the Miss Lime and Marmaton plays. With almost 100,000 net acres, these historic operations continue to provide steady production and future development opportunities.

Key Facts:

  • Net Acres: Almost 100,000
  • Potential Recovery: 145 MMBoe
