As carbon capture, utilization, and storage (CCUS) continues to be of interest in legacy oil fields around the U.S.—specifically in Ohio’s Appalachian Basin—the Grimsby Sandstone, often referred to as the “Clinton Sandstone,” remains a viable CCUS candidate, both as a depleted reservoir and for enhanced oil recovery. Multiple Clinton fields in Ohio have recently been remapped and reexamined, as seen in the Midwest Regional Carbon Sequestration Partnership’s report (2020). However, the Gore Consolidated Oil Field (GCOF) of southeastern Ohio has received limited attention, primarily only for economic considerations, leaving a gap in understanding its detailed geology. Since its discovery in 1907, James W. Castle has done the most work on Clinton Sandstone in the GCOF, which was published in 1998 and 2001. Sands identified by Castle in available cores were all interpreted as marine shoreface deposits, including shelf-bar complexes dominated by waves and tides before a returning transgression shifted the siliciclastic depositional environment back to a widespread carbonate factory. Previous work in this study from 2024–2025 included reexamining and comparing all available Clinton GCOF cores studied by Castle and stored at the Ohio Geological Survey core repository. Additional data for the cores were collected through the DOE National Energy Technology Laboratory, including XRF analyses and CT scans showing overlooked features such as ichnofossils, cementation variation, and subtle bedding. New, detailed core descriptions were completed along with facies descriptions and interpreted depositional environments. This study then takes the work a step further, utilizing the core work, 117 digitized LAS well logs, and over 950 depth-registered raster geophysical logs in the GCOF to apply sequence stratigraphic principles to the Clinton Sandstone. Sequence boundaries and major/minor flooding surfaces are identified; in addition, shale/sand cutoffs were applied on gamma-ray logs to more accurately map sand-body morphologies at a high resolution in the field between surfaces. Final maps and cross sections generated for the GCOF, along with prior core work, showcase the incredible heterogeneity present in the Clinton reservoir, now reinterpreted as a potentially tidally influenced deltaic setting with associated depositional environments. Understanding the complex heterogeneity of the sand-body morphology presented is critical for assessing the viability of the Clinton GCOF as a future carbon storage unit.
