Shale oil, despite its substantial reserves and significant development potential, presents a great extraction challenge. The existence of micro- and nanopores within shale formations renders conventional recovery methods largely ineffective, resulting in a limited recovery factor. With stronger adsorption, CO2 enables...
To improve the accuracy of fracture geometry interpretation using water hammer data, we propose the G-function-based resistive/capacitive/inertance (G-RCI) model to address the limitation of the traditional RCI equivalent-circuit water hammer model, which neglects closure-related pressure decline after shut-in. The G...

The Qiongzhusi Formation, a thick and vertically heterogeneous marine shale sequence in southern China, presents substantial obstacles to efficient hydraulic stimulation when conventional horizontal-well staged fracturing is applied, owing to marked interlayer contrasts in mineralogy, rock mechanics, and natural fractu...
