CO2 Pre-Fracturing Full Life-Cycle Simulation and Parameter Optimization Considering Geomechanics and Dynamic Fractures in Shale Oil Reservoirs
Hydraulic fracturing is essential for shale oil development, but conventional water-based fracturing fluids may cause formation damage and environmental concerns because of incomplete flowback. Employing CO2 as a prefracturing fluid is a feasible and promising approach. However, the enhanced oil recovery (EOR) perfor...
