Multiwell Experiment final report: 3. The coastal interval of the Mesaverde formation
The Department of Energy's Multiwell Experiment (MWX) is a field laboratory in the Piceance Basin of Colorado which has two overall objectives: to characterize the low permeability gas reservoirs in the Mesaverde Formation and to develop technology for their production. Different depositional environments have created distinctly different reservoirs in the Mesaverde, and MWX has addressed each of these in turn. This report presents a comprehensive summary of results from the coastal interval which lies between 6000 ft and 6600 ft at the MWX site. The interval is a complex, upper delta plain, depositional environment consisting of interbedded sandstone channels, and carbonaceous siltstones and mudstones. Separate sections of this report are background and summary site descriptions and operations; geology; well testing, stimulation, analysis, and reservoir evaluation of a pair of distinct sandstones; supporting laboratory studies; hydraulic fracture diagnostics; and a bibliography. Additional detailed data, results, analyses, and data file references are given on microfiche in several appendices. Overall, the results show that the coastal contains very low permeability reservoirs of limited extent and productivity. Nevertheless, the results provide additional insight into the geology and gas production from Mesaverde reservoirs. 131 refs., 217 figs., 41 tabs.
