Analysis on fracture propagation law and fracturing parameter sensitivity of CO₂ foam fracturing in deep coalbed methane reservoirs of Shenfu block

In the Shenfu block, deep methane reservoirs from coal seams at depths of 2000-3000 m face challenges such as high water consumption during conventional hydrofracturing, elevated treatment costs for the resulting fluids, and limited effectiveness in modifying the fracture network. CO2 foam fracturing, as a transformati...
