CO2 fracturing is one potential technique to relieve environmental issues related the massive hydraulic of hydrocarbon reservoirs. We summarize fundamental studies on overall procedures and analyze research progress fracturing, propping induced fractures permeating into, then recovering hydrocarbons from, formation. The key controlling characteristics in at each stage are defined, together with...

in this paper, a finite element model is developed for the fully hydro-mechanical analysis of hydraulic fracturing in partially saturated porous media. the model is derived from the framework of generalized biot theory. the fracture propagation is governed by a cohesive fracture model. the flow within the fracture zone is modeled by the lubrication equation. the displacement of solid phase, and...
