Along with horizontal drilling techniques, multi-stage hydraulic fracturing has improved shale
gas production significantly in past decades. In order to understand the mechanism of …

Abstract Development of numerical methods for hydraulic fracture simulation has
accelerated in the past two decades. Recent advances in hydraulic fracture modeling and …

Naturally fractured rock mass is highly inhomogeneous and contains geological
discontinuities at various length scales. Hydraulic fracture stimulation in such a medium …

A propagating fluid driven fracture in a rock mass is expected to interact with geological
interfaces on a wide variety of length scales. The vertical growth of hydraulic fractures in …

Hydraulic fractures represent a particular class of tensile fractures that propagate in solid
media under pre-existing compressive stresses as a result of internal pressurization by an …

The effects of rock inherent heterogeneity and grain size on hydraulic fracture initiation and
propagation for different propagation regimes are investigated through two dimensional …

This work presents phase field fracture modeling in heterogeneous porous media. We
develop robust and efficient numerical algorithms for pressure-driven and fluid-driven …

This article reviews the effect of weak interfaces on crack propagation in rock and some
other analogous brittle materials from phenomenon to mechanism. In this review, a variety of …

Hydraulic fracturing is widely accepted and applied to improve the gas recovery in
unconventional reservoirs. Unconventional reservoirs to be addressed here are with very …

Hydraulic-fracturing treatments have become an indispensable part of well completion in
shale gasfield development. Shale formations often contain natural fractures, and complex …
