OPEN-FILE REPORT 543

OFR-543RESERVOIR CHARACTERIZATION OF CLASTIC CYCLE SEQUENCES IN THE PARADOX FORMATION OF THE HERMOSA GROUP, PARADOX BASIN, UTAH
Bruce D. Trudgill and W. Curtis Arbuckle

This extensive report includes maps and correlations of the evaporite facies within the Pennsylvanian Paradox Formation throughout the northern Paradox Basin. This includes correlation of individual evaporite cycles and their respective clastic zones. The resulting associations are used to better understand the cyclicity of the Paradox Formation and its relationship to the structural development and evolution of the Ancestral Rocky Mountain Uncompahgre uplift.

The report includes a discussion of regional geology; evaporite depositional cycles and environments, regional correlations, clastic interbeds and salt (halite) lithologies; climate controls on evaporate cyclicty; well and outcrop data analysis including QEMSCAN analysis; structural and sequence stratigraphic discussions of the Paradox Basin and Uncompahgre uplift. The report includes five tables, 70 figures, and appendices of well database, isopach maps, and evaporate cycle age estimates. This work was funded by the Utah Geological Survey under the “Characterization of Utah’s Hydrocarbon Reservoirs and Potential New Reserves” program (FY 2007).
