The core workshop aims to instruct the attendants on the sedimentology and stratigraphy of the Wilcox Group, onshore Texas. Several key drill cores, associated wireline well-logs, and palynological and geochemical datasets are used to illustrate the dominant sedimentary processes, depositional system evolution, and provide insights into paleoclimate, paleogeography, and the potential for regional correlation. Petrophysics will provide estimates of the reservoir properties and assessment of the controls on reservoir quality and feasibility for CO2 storage. The field course focuses on Paleocene-Eocene Thermal Maximum (PETM) deposits of the Wilcox group near Bastrop, TX. This is an extension of the core workshop and will allow participants to see laterally-extensive outcrops that contain some of the facies they saw in core. The goal is to examine sedimentologic, ichnologic, biostratigraphic, isotopic, and geochemical trends within the PETM interval and overlying Carrizo Sandstone, discuss paleoenvironmental evolution, and propose regional correlations based on this new dataset. Outcrops will provide the opportunity to discuss stratal architectures and examine key surfaces that are not evident in drill core. Cost includes transportation for the field trip on day 2 (bus), one night hotel stay in Austin, Texas (double occupancy), use of materials at the facility, lunches, snacks, and water.
