Crimson Exploration Inc. Provides Operational Update.

HOUSTON -- Crimson Exploration Inc. (OTCBB:CXPO) today provided an operational update on production and drilling activity through the second quarter 2008.

Production Update

Crimson reported production of an estimated 4.8 Bcfe of natural gas equivalents, or approximately 53,200 Mcfe per day, for the second quarter of 2008, an increase of approximately 52% over the approximate 3.2 Bcfe, or 34,900 Mcfe per day, produced during the second quarter of 2007. The dramatic increase in production was primarily attributable to a full quarter of production in 2008 from the South Texas and Gulf Coast producing assets acquired from EXCO Resources, Inc. in May 2007, new production from the producing properties acquired from Smith Production at the end of May 2008 and new production added at various points during 2007 and 2008 resulting from the success of our drilling programs. As of the end of July, we were producing approximately 61,500 Mcfe per day, with the recent increase in production resulting from the properties acquired from Smith (beginning May 31, 2008), the previously announced initiation of production from the Catherine Henderson #6 well in our Willis Marsh Field in Liberty County in mid June and the commencement of production from the recently drilled Henderson #7 well, also in Liberty County, at the end of July.

Drilling Activity

Liberty County, Texas - Felicia

Building upon the success we have had in this area since we acquired it in May 2007, we have drilled three more exploitation wells in this county since the first quarter, all of which were successful. We have now drilled a total of ten exploitation wells in this area since its acquisition, nine of which have been successful. Successes subsequent to the first quarter were the previously announced Catherine Henderson #6 well in the Cook Mountain formation in the Willis Marsh Field, which commenced production in late June at an initial gross rate of approximately 13,900 Mcfe/day (7,025 Mcfe/day, net to our interest). In July 2008, we also completed the Henderson #7 (73.3% WI) exploitation well in the Felicia Central area of the county, an 11,300 foot test of the Yegua EY1 and EY2 sands and commenced production in July at an initial gross rate of 10,000 Mcfe/day (6,300 Mcfe/day, net). We have logged an apparent success, and are preparing to complete the Henderson #8 exploitation well (73.3% WI) in the Yegua EY2 sand at 11,600 feet. We will continue to be active in the Liberty County area for the remainder of this year and 2009, with an estimated two to four more exploitation wells and one development well anticipated for the remainder of the year.

Lavaca County, Texas - SW Speaks

We recently completed the Migl-Quinn #9 well, our first operated well in the SW Speaks Field (34.4% WI). This development well was drilled to a total depth of 15,000 feet, was completed in the Magnolia sand and commenced production in mid-July at a gross rate of 2,100 Mcfe/day. We are currently drilling the Pilgreen #15 exploitation well (36.7% WI) in this field, targeting the Wilcox, and are at 11,200 feet toward a 14,500 foot objective. We anticipate drilling one more development well in this area during 2008.

Brooks County, Texas - Cage Ranch 

The Cage Estate #G-4 development well (55.3% WI) was drilled and completed in the 8,700 foot sand and commenced production in June at a gross rate of 2,100 Mcfe/day. The G-4 is the first of a four well drilling program (two development wells and two exploitation wells) planned in this field for 2008.
