Citation established a presence in the Rocky Mountains in the late 1980's with the acquisition of properties from Tenneco and Mobil located in Utah, Wyoming and the four corners area of New Mexico. In 1995, Citation became a significant operator in the Rockies with the purchase of Apache Oil Corporation's Rocky Mountain assets. Citation has continued to purchase assets in the region, including acquisitions from Hunt Oil Company, PITCO, Meritage, and Journey. Citation operates primary and secondary recovery projects in Wyoming, Montana, North Dakota and South Dakota. Citation is the seventh largest oil producer in the state of Wyoming.
In addition to its oil operations, Citation is very active in the coalbed methane (CBM) gas play in Campbell County, Wyoming. Citation has a large drilling program under way to develop CBM resources in its Triangle U Unit, just south of Gillette. Citation has additional CBM acreage under various stages of development.
The Rocky Mountain Region office is located in Gillette, Wyoming.

Bowes
The Bowes Field, which was acquired from Apache in 1995, is located in northern Montana on the north flank of the Bear Paw uplift and includes oil productive reservoirs of the Jurassic Sawtooth formation as well as shallow gas productive reservoirs within the Cretaceous Eagle sandstone formation. Oil production is unitized under the Citation operated Bowes Sawtooth Unit (BSU), while Eagle gas production is on a lease basis. The BSU was producing 140 Bopd prior to Citation beginning a horizontal drilling program on the southern and eastern flanks of the unit in the second and third quarters of 2007. The four well drilling program increased BSU's oil production to over 700 Bopd from 37 wells. Citation is planning to drill additional horizontal Sawtooth wells in 2008 as a follow-up to the successful 2007 drilling program. In addition to future drilling, Citation is also evaluating an increased pressure maintenance program to build reservoir pressure in depleted areas of the field to enhance recovery and allow for future horizontal drilling in these areas.
Little Buffalo Basin
The Little Buffalo Basin and Northwest Dome properties are situated in the Big Horn Basin on the Hot Springs County and Park County, Wyoming line. The town of Meeteetse is located approximately six miles north of the field. The field is a classic breached anticlinal feature that produces oil under a secondary waterflood recovery process primarily from the Permian Phosphoria (Embar) and Pennsylvanian Tensleep formations at depths of 4,500' and 4,750', respectively. The property was acquired from Apache Corporation in 1995 as part of their Rocky Mountain regional exit. Gas production occurs from the shallower Muddy and Frontier sands. Current gross production is over 1,517 Bopd and 709 Mcfd (502 Mcfd sales) from 136 active oil and gas producers and 93 water injection wells. Recent development activity has focused on higher oil cut Embar recompletions and Tensleep/Embar reactivations throughout the 35 square mile complex.
Little Knife
Located in the southern portion of the Williston Basin of North Dakota and part of the 1995 Apache acquisition, Little Knife Field produces approximately 1,407 Bopd and 4,305 Mcfd from 4 active company operated and 60 Petro-Hunt operated wells. The major reservoir is the Mission Canyon Formation encountered at a depth of 9,700'. In 1998 Citation acquired a 60 square mile 3-D seismic survey to investigate deeper intervals and image the existing Mission Canyon reservoir. The analysis of the data resulted in the drilling of the Zabolotny #8-4 well. It was completed in the Red River Formation (13,500'), and the well is expected to produce in excess of 3 Bcfg and 40 MBO, thus proving the deeper development potential of the field.
South Casper Creek
At the end of 2005, Citation was successful in purchasing the interest of Meritage Energy in numerous properties situated predominantly in the Wind River and Powder River Basins of Wyoming. South Casper Creek is located on the east flank of the Wind River Basin in Natrona County and produces 335 Bopd from 57 producers in the Tensleep Formation at a depth of 2,500'. This 100% WI field contains significant upside to recover tertiary reserves through thermal recovery methods. Facilities and infrastructure are already in place to exploit the Tensleep in the South Dome area based upon the success of a pilot program that was in place from 1981 through 1985 and later expanded from 1988 through 1992. With the continued stabilization of current commodity prices, this type of project exhibits attractive economics and will be further exploited.
Triangle U
The Triangle U Field is part of the 1995 Apache acquisition and is located in the southern portion of the Powder River Basin. Initially, production was only from the Sussex Formation at a depth of 8,400'. Two horizontal wells were drilled by Citation to complete the Sussex development. The field currently produces 50 Bopd from 12 active producers. Initial offset activity and intensive reservoir study by Citation have identified the shallower Big George Coal Seam at a depth of 1,100' as a source for the potential development of over 40 Bfcg of reserves from 160 locations. Currently there are approximately 150 Big George CBM wells that are on production. After an initial period of dewatering, first gas sales occurred in September 2004. Current gas sales are approximately 11,000 Mcfd and inclining.
