Hydraulic Fracturing Modeling: A Microporomechanics Approach
The full realization of the global potential of organic-rich shale as an energy source depends on many factors. However, the most fundamental of all is the ability to characterize and model the complex behavior of these geomaterials. This is a crucial step in exploitation of shale formations since the desired efficiency and efficacy of a hydraulic fracturing operation and Estimated Ultimate Recovery (EUR) of a reservoir are highly dependent on it. The heterogeneous nature and anisotropic behavior of organic-rich shale challenges traditional hydraulic fracturing models. This paper proposes a microporomechanics approach within the framework of Linear Elastic Fracture Mechanics (LEFM), to derive an expression for energy release rate for an arbitrarily oriented pressurized crack embedded in a linear elastic transversely isotropic medium subjected to anisotropic in situ stresses. The attractiveness of this method arises from its flexibility to capture small scale material behavior and to upscale their contribution up to reservoir scale within a systematic and mechanistically consistent framework.
