CO2foam fracturing fluid has received significant attention because of its versatility in water-sensitive formations. However, the mechanisms of hydraulic fracturing of shale reservoirs by CO2foam fracking fluid, in terms of fracture initiation and propagation remain unclear. In this paper, an exper...
