Title: Approximation of continuity of lenticular Mesaverde sandstone lenses, utilizing close-well correlations, Piceance Basin, northwest, Colorado. Western Gas Sands Project

Abstract

Mesaverde Group sandstone units in 13 closely-spaced wells in the central and southern Piceance Basin of Colorado were correlated utilizing wireline log response quantitatively and qualitatively. Based on these correlations, the environmental subdivisions of the Mesaverde Group were characterized as follows. Paralic (upper mixed-marine) zone, occurring in the uppermost Mesaverde, includes thick sandstone units which are interpreted to be regionally continuous. Fluvial zone, containing point-bars 20 to 30+ ft thick, is interpreted to be correlatable to a maximum of 6800 ft. Paludal zone, which has insufficient data to adequately characterize the sand units. However, 63 percent of the units are correlatable across at least 139 ft. An approximation of the dimensional characteristics of Mesaverde sandstone units has potential applications in designing hydraulic fracturing treatments and estimating gas reserves more accurately. 16 figures, 2 tables

    Mesaverde Group sandstone units in 13 closely-spaced wells in the central and southern Piceance Basin of Colorado were correlated utilizing wireline log response quantitatively and qualitatively. Based on these correlations, the environmental subdivisions of the Mesaverde Group were characterized as follows: (1) paralic (upper mixed-marine) zone, occurring in the uppermost Mesaverde Group, includes thick sandstone units which are interpreted to be regionally continuous, (2) fluvial zone, containing point-bars 20 to 30+ ft thick, is interpreted to be correlatable to a maximum of 6800 ft, and (3) paludal zone has insufficient data to adequately characterize the sand units. However, 63 percentmore » of the units are correlatable across at least 139 ft.

    To help find solutions to problems in obtaining gas production from channel sandstones in the Greater Green River Basin in Wyoming, we studied outcrops of equivalent rocks in three areas: Rock Springs Uplift, Hoback Basin, and Cretaceous Mountain. Formations studied were: Paleocene (Ft. Union equivalent), Hoback, Lance, Mesaverde (Hoback Basin), Ericson, and Rock Springs. Besides a photographic survey of channels in the areas, detailed measurements were made on 25 channels. About 80 structural elements (parallel inclined and trough cross beds) in each channel were measured for height and dip orientation. The most comprehensive data was obtained on the Rock Springsmore » Formation.« less

  • The Rulison Field has produced a total of 7012 MMCF of gas and 4897 barrels of oil from 1956 through 1981. This report summarizes the completion procedures and illustrates the production decline for those wells contributing to the cumulative total. Emphasis is on those wells producing from the Mesaverde Group. Two government-sponsored research wells (MWX-1 and MWX-2) have drilled and cored the entire Mesaverde section.

    The Deep Coal Seam Project and the Western Cretaceous Coal Seam Project of the Gas Research Institute (GRI) have funded significant research efforts in the Piceance and San Juan basins of western Colorado, and southwestern Colorado and northwestern New Mexico respectively to further the knowledge of coalbed natural gas reservoir development. Since 1983 these efforts have spanned the majority of the technologies applied by operators of wells in both conventional and unconventional gas reservoirs. The report discusses the evaluation efforts for the Conquest Oil Company South Shale Ridge No. 11-15 well, and the significance of these data in terms ofmore » producibility of natural gas from Cameo coals of the Mesaverde Group (Upper Cretaceous) in the Piceance Basin.« less
