Crimson Exploration Inc. Announces Successful Completions in the Eagle Ford Oil Window and in Liberty County, TX
Houston, TX – (BUSINESS WIRE) – April 11, 2011 - Crimson Exploration Inc. (NasdaqGM: CXPO) announced the successful completion of the Littlepage McBride #1 (53.0% WI), located in Karnes County, TX and targeting the Eagle Ford Shale, commencing production in the first week of April at a gross daily rate of 876 barrels of oil and 717 Mcf of natural gas on a 14/64th choke with 2,845 psi of flowing tubing pressure. The well was drilled to a total measured depth of 15,885 feet, including a 4,800 foot lateral, and was finalized, from spud to first production, in 70 days.  The Littlepage McBride represents Crimson’s first well on its 1,250 gross acre position in Karnes County, which is adjacent to other significant drilling and producing activity in the oil window of the Eagle Ford play. The Company intends to follow its restricted rate philosophy, currently being utilized in the East Texas Haynesville play, in its Eagle Ford program and does not anticipate increasing the rate further, although the well performance to date suggests it is capable of much higher rates.

Allan D. Keel, President and Chief Executive Officer, commented, “The successful completion of the Littlepage McBride validates Crimson’s position in the oil bearing window of the Eagle Ford Shale in Karnes County. Given this initial success in Karnes County and current crude oil prices, Crimson plans to reallocate additional capital to accelerate drilling activities in Karnes County in 2011 to optimize cash flows and shareholder return on oil weighted opportunities.  We have also been fortunate enough to have obtained scheduling commitments from our drilling and completion services providers that will enable us to pursue our drilling plans for all of 2011 without delay risks related to the tight market for those services.”

In Liberty County, TX, the Catherine Henderson #A-9 (66.0% WI) commenced production at the end of March at a gross daily rate of 9.6 Mmcfe, or 4.4 Mmcf, 578 barrels of condensate and 286 barrels of natural gas liquids on a 12/64th choke and 7,200 psi of flowing tubing pressure. This well was drilled to a total measured depth of 13,150 feet in the Cook Mountain formation.  Crimson is currently drilling below 12,850 feet on the Catherine Henderson B-4 (64.0% WI) toward a total measured depth of 13,500 feet and is scheduled to spud the Catherine Henderson A-10 (66.0% WI) in May.

In our Bruin Prospect Area of San Augustine County, TX, we have successfully completed 14 stages of frac on the Kodiak #1 well (70% WI) in the Mid Bossier Shale and expect initial production to begin within the next two weeks. Completion operations have commenced in the Haynesville Shale formation on the Blue #1 well (70.7% WI), also in the Bruin Prospect Area, with initial production expected around the first of May.

We anticipate spudding the KM Ranch #1 well, our first Eagle Ford well in Zavala County, TX, by the beginning of May.  We have approximately 4,675 gross acres (50% WI) in Zavala County that we believe to be prospective in the oil window of the Eagle Ford Shale.  This operated well is expected to be drilled to a total measured depth of approximately 12,500 feet, with a projected 5,500 foot lateral.
