The Mesaverde Formation in the Northeast portion of the Uintah Basin is being evaluated to demonstrate the ability of the low permeability reservoirs to economically produce gas after massive hydraulic stimulation. Precontract conditions stated that stimulation would be conducted only upon confirmation of minimum reservoir conditions as determined by reservoir evaluation. The evaluation was done by a combination of drillstem testing, logging, coring, mini-fracturing to determine the in-situ stress field and fracture direction as well as the lab tests on cores. The hydraulic fracturing would be performed only if gas bearing sandstone could be shown to aggregate gas transmissibility of 0.5 millidarcy-feet in the lower Mesaverde and 1.0 millidarcy-feet in the upper zones. The test well was drilled to a total depth of 9282 feet. Production casing was run, and subsequently eight sandstone zones were perforated to test for feasibility of gas production. These zones were selected from critical analyses of drillstem tests, gas logs and open-hole logs. Although all zones showed gas production in small amounts, each zone produced water in varying amounts. Analysis of flow test data indicated that none of the zones met the minimum transmissibility requirements and therefore no massive hydraulic fracturing was performed in the Mesaverde.
