Course Description:
This fieldtrip focuses on the Woodford Shale in south-central Oklahoma. We will make 5 to 6 stops selected from an extensive set of outcrops described in an accompanying guidebook that synthesizes decades of studies overseen by Brian Cardott, Paul Philp, Jim Puckette, and Roger Slatt. The stops represent a 100mi/162km progressive basinward transect from the Lawrence Uplift through the Arbuckle Mountains to the Criner Hills uplift in the Ardmore Basin. The lithostratigraphy observed in these outcrops will be placed within a well-defined regional sequence stratigraphic framework and key aspects of source rock richness and geomechanics will be discussed. The overarching theme of this trip is placing the Woodford petroleum system into the much larger framework of Late Devonian to Early Mississippian paleogeography and basin geometry as pertaining to controls on organic carbon and phosphate/REE sequestration. We will also examine outcrops across two major mass extinction boundaries (Frasnian-Famennian and Devonian-Carboniferous) and discuss the potential drivers behind those events.
Field Trip Leader Bios:
David Hull studied undergraduate geology at Texas A&M and earned his Master’s degree in Geology from the University of Texas, focusing on the sedimentology, petrology, and reservoir characteristics of shales and carbonates. He started work at Chesapeake Energy before moving to Devon Energy. At those companies David primarily worked in geologic technology groups assisting business units to improve their understanding of various reservoirs through integration of core descriptions and thin sections. As an independent geologist David continues this work as the Founder of Practical Geoscience and Petrography.
Andrew Cullen holds a trifecta of degrees in geology from the University of Oregon and the University of Oklahoma where he studied igneous petrology and structure-tectonics. His industry lineage includes Shell International, EOG, Chesapeake, and the Warwick Investments Group. Currently, Andrew is an adjunct professor in the OU College of Law and, although retired from industry for two years, he maintains active research programs on the tectonics of Southeast Asia, the structural geology & tectonics of Oklahoma, and the paleoceanography of Devono-Mississippian of the Midcontinent. Almost all his research has a component of field work. It’s where the rocks are. He is a frequent contributor of technical and outcrop articles to the OCGS Shale Shaker. As a reviewer for Tectonophysics, the Journal of Asian Earth Sciences, and Tectonics, as well as serving of various boards and committees for AAPG, OCGS, and the University of Oklahoma Andrew also has a strong record of service to the earth science community.
