Broadly speaking, the Mid-Continent oil and gas province contains hundreds of fields and has produced more oil than any other area in the United States since the first discovery was made in 1892. This area has a long history 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 takes place in the Woodford Shale in Western Oklahoma. Horizontal drilling accompanied with multi-stage fracture stimulation has unlocked this significant resource. Cimarex drilled its first horizontal Woodford well in 2007 and continues the multi-well infill drilling program that commenced in 2012.
Woodford wells target the liquids-rich Woodford shale formation which varies in thickness from 120–280 feet at depths of 11,000-16,000 feet throughout Cimarex’s acreage. The infill program is taking place in the heart of the play in Canadian County, Oklahoma. Cimarex has participated in over 800 Woodford Shale wells since 2007 and has approximately 128,000 net acres in the liquid-rich portion of play representing multiple years of drilling opportunity.
In addition to the Woodford shale, Cimarex is actively testing the Meramec Shale. The Meramec sits above the Woodford Shale and early results have been encouraging.
The Mid-Continent accounted for 63 percent of Cimarex’s year-end 2015 proved reserves and 44 percent of total production.
