Event Details


Wolfcamp A, Dean, and Sprayberry strata of the Lower Permian Leonardian series contain major unconventional landing targets in the Midland Basin. It is vital to have detailed knowledge of the three-dimensional reservoir architecture and internal lithofacies in order to economically extract oil and gas from these units. Although cores provide the best way to assess lithofacies, cores are rare compared to the vast, historical archive of wireline logs available from Midland Basin vertical wells. As such, we core-calibrated wireline-log suites and applied the calibrations from widely-distributed wells to facilitate the identification and mapping of major Leonardian reservoir units and their respective facies throughout the entirety of the Midland Basin. Maps and cross sections derived from this methodology are useful in their own right, but the knowledge also provides foundational data for subsequent 3-D geomodelling, e.g., as fundamental input for TORA’s Midland Basin and Delaware Basin geomodels.

David L. Carr is a geologist whose primary interests and skills lie in subsurface stratigraphy and reservoir characterization. He has worked for 4 decades in a variety of roles in oil & gas exploration and production, natural gas storage, carbon sequestration, and regional stratigraphic projects, mainly in U.S. basins. David holds Geology degrees from Colorado State University (B.S.) and the University of Texas at Austin (M.A.).
