Crimson Exploration Provides Update on Madisonville-Rodessa Project.

HOUSTON -- Crimson Exploration Inc. (OTCBB:CXPO) today announced that it has reached total depth on its Johnston #2 well in its Madisonville Field in Madison County, Texas. The well was drilled to a total depth of 12,635 feet and encountered the Rodessa Formation within the productive limits of the reservoir. Within the next two weeks, the rig will be moving to the Fuhlberg #1 location approximately one mile southeast of the Johnston #2, also targeting the Rodessa. Final results on both the Johnston and Fuhlberg wells in this competitive reservoir will be released when completion and testing is finalized, which is expected to be by the end of December. A smaller second rig has been contracted to begin drilling of the waste disposal well. Production from our development of this reservoir is projected to commence in the first quarter of 2007.

The Company has approximately 2,400 acres in the Rodessa Prospect Area in Madison County on which we will drill as many as four wells over the next six to twelve months, depending on rig availability and reservoir information obtained in drilling the initial two wells. Crimson will have an approximate 68% working interest (approximate 51% net revenue interest) in these wells and will operate the drilling, completion, and production of each well. The Rodessa formation is a sour gas reservoir that has been a prolific producer in the area since May 2003. The Johnston #2 well offsets two wells which are producing approximately 15,000 mcf of natural gas per day into a capacity limited sour gas processing plant. The adjacent operator has also drilled two additional wells in the Rodessa that are shut-in and awaiting the current expansion of the gas plant to 70 Mmcfe per day. The plant expansion is projected to be completed in the first quarter of 2007 and coincides with expected initial production from Crimson's current activity. Plant processing capacity will be allocated based on proportionate deliverability from all wells producing sour gas from the Rodessa. All production rates from the Rodessa formation are gross production rates, prior to reduction for inert gases of approximately 30 percent.
