Characterization of Lower Ordovician Ellenburger Dolomite in the Permian Basin

Explore a detailed reservoir description of the Lower Ordovician Ellenburger Group in West Texas through this 51-minute lecture by Dr. Bob Loucks, Senior Research Scientist at the Bureau of Economic Geology. Examine the depositional setting, lithofacies, pore networks, and impact of karst processes on reservoir geology of a 1155 ft continuous core from Upton County, Texas. Gain insights into the origin and characteristics of pore types relevant for waste-water disposal and CO2 storage. Analyze the stratigraphic sequence, including microbial thrombolite complexes, oolites, evaporites, and peritidal complexes. Understand the effects of intense meteoric karsting on the upper 700 ft of the Ellenburger Group. Investigate pore networks, porosity, and permeability characteristics at various depths. Discover how these pore systems support hydrocarbon production and their potential for waste-water disposal and CO2 storage.
