The document summarizes research on the potential for carbon sequestration in the Early Pennsylvanian Breathitt Group located in the central Appalachian Basin. The research aims to characterize reservoir properties and investigate storage capacities of shales and sandstones in the region. Core samples and outcrop measurements were analyzed alongside geophysical well log data to develop a sequence stratigraphy model identifying regional lithologies suitable for CO2 storage and sealing. The model found broad flooding surfaces and discontinuities indicating opportunities for targeted sequestration in the Pocahontas Basin. Further work will focus on the interplay of forces controlling basin development.
