... Abstract Numerical simulation of hydraulic fracture propagation is increasingly used to evaluate the effect of various mechanistic aspects (e.g., inclusion of poroelastic effects, proppant transport, etc.), and of several variables, on the result of a stimulation operation at varying scales...

... under true-triaxial compression. The injection scheme consists of a hydraulic fracturing cycle followed by a few fracture propagation cycles and several injection/falloff (DFIT) cycles. The wellbore pressure and acoustic emission (AE) activities of each cycle were concurrently measured to monitor...

... Abstract Many researchers reported that porosity and, to less extent, sedimentary fabric are the main controlling aspects of acoustic wave propagation in carbonate reservoirs. In this study, we focused on microporous microfacies of shallow marine, deeply-seated tight carbonate reservoir from...

... effects would result in the initiation and propagation of multiple hydraulic fractures to form the so-called fracture swarms at some distance away from the hydraulic fracture surfaces. Such a possibility might exist under some special conditions e.g., flow in natural fracture or other higher permeable...

Advanced geomechanical modeling was performed to simulate the hydraulic fracture propagation and the resulting strain responses in the vertical direction. The modeling results demonstrated...

... of the complexity of hydraulic fracturing itself and the complex distribution of stresses around wellbores, accurately describing the behaviors of hydraulic fractures is still a challenging task. We propose a numerical method to simulate arbitrarily propagating of hydraulic fractures from a wellbore, emphases...
