Rock Physics Study of Lacustrine Shales and Applications in Geophysical Prediction of Sweet Spot
Rock physics analysis is crucial in bridging seismic data with reservoir properties. Although shale oil reservoirs are considered to be significant hydrocarbon resources, their exploration and extraction still pose challenges, especially in lacustrine shale environments. I conducted a comprehensive …
