The Late Pennsylvanian Wolfcamp D (i.e., Cline Shale) in the Midland Basin, Texas is an organic matter-rich mudrock that can be subdivided into the underlying Canyon and the overlying Penn-Cisco subunits. The primary objective of this research is to develop a high-resolution facies model for the Wolfcamp D across the Midland Basin that integrates lithologic core descriptions, high resolution X-ray fluorescence core scanning, and core-plug analyses into a basin-scale stratigraphic framework built on wireline log correlations. Data from eight cores are integrated in this study, with formation tops for the Strawn, Canyon, and top of Wolfcamp D picked on 3000+ wireline logs across the Midland Basin.
Research Objectives:
Toti E. Larson is a Research Associate Professor and the Principal Investigator of the Mudrock Systems Research Laboratory (MSRL) at the Bureau of Economic Geology, University of Texas at Austin. With over 20 years of experience in geochemistry and subsurface geology, he leads research initiatives that focus on characterizing unconventional reservoirs and advancing our understanding of mudrock systems.
Since taking the helm of the MSRL in 2019, Larson has collaborated with energy companies to identify knowledge gaps and develop innovative subsurface characterization projects. His research integrates geochemistry, geology, and machine learning to create predictive models for subsurface characterization. Notably, Larson developed CorePy, an open-source Python package designed for sharing subsurface characterization tools and workflows.
Larson has a strong background in stable isotope geochemistry, gas chromatography, and X-ray fluorescence analysis. He is also skilled in data science, utilizing tools such as Python and MATLAB for statistical analysis and machine learning applications.
His contributions to the field have been recognized with awards such as the Jules Braunstein Memorial Award from the American Association of Petroleum Geologists in 2019. Additionally, he has served in various leadership roles, including President of the Austin Geological Society and Technical Chair for multiple conferences.
Larson's work not only enhances academic research but also fosters collaboration between academia and industry, making significant strides in the understanding of subsurface resources.
