Chaparral Energy is an independent oil and gas producer and operator with headquarters in Oklahoma City, Oklahoma and field offices throughout the south central United States. Chaparral, co-founded by CEO Mark Fischer, has experienced steady growth since beginning its operations in 1988. Although predominately a Mid-Continent and Permian Basin producer, Chaparral has operations extending from off-shore gulf coast in south Texas, east to Mississippi, west to Utah and north to North Dakota. In the beginning, the company primarily targeted acquisition opportunities operated in environments that had been marginal or abandoned by other producers. The company has become known for its expertise and specialization in well rejuvenation. Recently Chaparral has transitioned from mostly an acquisition company into an active drilling company and in 2004 began acquiring license rights to existing 3D seismic to evaluate additional drilling opportunities. Chaparral is also known for its expertise in enhanced oil recover (EOR) and has a large inventory of carbon dioxide (CO2) tertiary recovery projects in the Mid-Continent and Permian Basin. To support the EOR program, the company owns interests in 389 miles of CO2 pipelines, and through its growing infrastructure it hopes to eventually have a dominate position in this developing market in Oklahoma. Chaparral plans to sustain its growth through a balanced program of acquisitions, exploitation, development and exploration.
