Mid-Continent

The Mid-Continent oil and gas region contains hundreds of fields, producing more oil than any other area in the United States since the first oil discovery in 1892. This area has a long history of drilling activity and still provides exceptional opportunities for exploration and production for companies like Cimarex.

Cimarex defines its Mid-Continent region as the Anadarko Basin in Western Oklahoma, Southern Oklahoma and the Texas Panhandle. The bulk of Cimarex activity is focused on the Woodford Shale and Meramec Shale in Western Oklahoma. Horizontal drilling and multi-stage fracture stimulation enabled the economic development of this significant resource.

The liquids-rich Woodford Shale formation varies in thickness from 120 to 280 feet and is found at depths of 11,000 to 16,000 feet throughout Cimarex’s acreage. The company’s infill program is taking place in the heart of the play in Canadian County, Oklahoma. Cimarex has participated in more than 800 Woodford Shale wells since 2007 and has approximately 135,625 net undeveloped acres in the liquids-rich portion of the play and anticipates multiple years of multi-well infill drilling opportunities.

The liquids-rich Meramec Shale formation has thicknesses ranging from 140 to 600 feet and is found at depths of 10,000 to 13,500 feet throughout Cimarex’s acreage. Southeast Blaine County is the central portion of the play. Cimarex has participated in over 250 Meramec Shale wells since 2013 and has approximately 116,500 net acres in the liquids-rich portion of the play and anticipates multiple years of drilling opportunities.

The Mid-Continent accounted for 43 percent of Cimarex’s year-end 2018 proved reserves and 43 percent of total production. The Mid-Continent is expected to contribute approximately 30 to 35 percent of total 2019 production.
