Multiwell Experiment final report: 2, The paludal 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 paludal interval which lies between 6600 ft and 7450 ft at the MWX site. The interval is a complex, lower delta plain, fluvial depositional environment consisting of interbedded sandstone channels, carbonaceous siltstones and mudstones, and coals. Separate sections of this report are background and summary; site descriptions and operations; geology; log analysis; core analysis; in situ stress; well testing and analysis of one zone; well testing, stimulation, analysis and reservoir evaluation of another zone; 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 paludal is a complex and productive interval.
