HISTORY

The predecessor of Crimson Energy Partners III, L.L.C, Crimson Energy Company L.P., was founded in 1998 by President, Frank F. Starr II, and Vice President, Jacob (Tripp) Rivers III, with the objective of building a private, independent oil and gas company focused on core areas in which the principals had significant experience. The focus for growth was predominately in South Texas where the principals have an average of 15 years of experience. The original company was built through acquisitions and development drilling to over 160 BCFE of proved reserves. The assets of Crimson Energy Company, L.P. were sold in 2004 which resulted in a return on investment exceeding 40%.

Crimson Energy Partners III, L.L.C (“Crimson”) began operations in April 2005 with funding from EnCap Investments L.P. and is implementing a drilling strategy similar to its predecessor for development of its asset base. Crimson’s asset base includes 82,000+ acres in South Texas and approximately 11,000 acres in East Texas. Crimson is focused on maximizing growth in its asset base while dedicating itself to conducting business in a socially responsible and ethical manner.
