Title: Hydrogeologic subdivision of the Wolfcamp Series and Pennsylvanian System of the Deaf Smith study area, Texas: Revision 1, Topical report

Technical Report ·
OSTI ID:7051731

The Pennsylvanian-Wolfcamp section in the Palo Duro Basin includes brine aquifers that are considered to be the most important ground-water flow paths in the deep-basin system. This particular study area comprises eight counties in Texas, centered in Potter County (and including Deaf Smith County). Underground patterns of rock distribution are delineated from a hydrologic perspective and at a level of detail appropriate for numerical modeling of regional ground-water flow. In this study, hydrogeologic units have been defined as mappable, physically continuous rock bodies that function in bulk as water-transmitting or water-retarding units relative to adjacent rocks. Interpretations are made primarily from geophysical logs. Hydrologic characteristics are assessed on the basis of properties typically associated with certain lithologies (e.g., sandstones are more pervious than shales) and on the basis of gross variations in effective porosity (particularly in carbonate sequences). In this report, the Pennsylvanian-Wolfcamp section is subdivided into 41 hydrogeologic units. These units do not constitute a classical or definitive breakdown of the Pennyslvanian-Wolfcamp section. 12 refs., 87 figs., 1 tab.
