Crimson Exploration Announces First Successful Haynesville Shale Well

HOUSTON--(Business Wire)--
Crimson Exploration Inc. (OTCBB:CXPO - News) today announced that its Kardell
Gas Unit #1H well in San Augustine County, Texas, in which the Company owns a
52% working interest, was successfully completed in the Haynesville Shale
formation. The remaining 48% working interest is owned by the unit operator,
Devon Energy (NYSE:DVN).

The Kardell #1H was drilled to a total measured depth of 18,350 feet with a
total lateral length of approximately 4,500 feet and 12 stages of fracture
treatment. The Kardell #1H experienced one of the highest reported 24-hour
initial potential rates for a Haynesville Shale well (East Texas and North
Louisiana) at 30.7 million cubic feet of natural gas per day on a 37/64 inch
choke with 6,824 psi of flowing pressure. The well has been hooked up and is
currently flowing to sales. On a net basis to Crimson, and at this rate,
production from the Kardell well represents an approximate 31% increase over our
average daily production of 38.2 million cubic feet of natural gas equivalents
per day during the third quarter.

In addition to the Haynesville Shale formation, the well encountered a thick
Mid-Bossier Shale interval with characteristics similar to known Haynesville and
Mid-Bossier completions in East Texas and Louisiana. The Mid-Bossier represents
significant additional potential to Crimson`s leasehold position in the southern
portion of the East Texas Haynesville Play. The Kardell #1H also encountered
hydrocarbon shows in the shallower Knowles Lime, Pettet, and James Lime
formations, each of which are being evaluated for future drilling activity.

The Kardell #1H was drilled on the eastern edge of Crimson`s "Bruin" prospect
where it controls approximately 3,000 acres. The Company is currently in the
planning stages of several wells in the "Bruin" area that will further evaluate
and exploit these multiple formations beginning in early 2010. Crimson has an
additional 9,000 acres outside the "Bruin" area within Sabine and San Augustine
counties and expects to commence the initial well on that acreage in early 2010.

Allan D. Keel, Crimson President and CEO, stated - "The Kardell #1H well is
another transformational event for Crimson as it continues to build on its
multi-pronged strategy of acquisition, exploitation and exploration. We are very
pleased with the results from our first East Texas resource-play well and are
excited about the multi-pay potential underlying our approximate 12,000 acres.
Our early evaluation of the southern area showed similar potential in the
Haynesville as that seen in the Haynesville "Core Area" in North Louisiana, yet
it had the additional potential in the Mid Bossier. The Haynesville success
experienced in the Kardell #1H and recent Haynesville activity from offset
operators in this immediate area have proven this early concept. Crimson looks
forward to an active year of drilling in this area in 2010, both operated and
non-operated. Combining this longer life natural gas asset, with over 100
potential drilling locations in multiple formations in the Bruin prospect alone,
with our set of low risk, high return Gulf Coast exploitation opportunities and
South Texas exploration prospects, provides us with a balanced, high quality
inventory of drilling opportunities that should provide significant growth
opportunity for years to come."
