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 …

CO 2 injection is a promising method to rejuvenate the shale oil reservoirs after the primary
production. In this work, we comprehensively reviewed the CO 2 injection enhanced oil …

Unconventional resources like shale gas has been the focus of intense research and
development for two decades. Apart from intrinsic geologic factors that control the gas shale …

Natural fractures have long been suspected as a factor in production from shale reservoirs
because gas and oil production commonly exceeds the rates expected from low-porosity …

This paper presents a hybrid method for modeling hydraulic fracture propagation in an
unconventional shale formation with frictional and cemented natural fractures. The hybrid …

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 …

In recent times, particularly in the 21st century, there has been an alarming increase in the
demand for global energy, along with continuous depletion in conventional oil reservoirs …

Both microseismic interpretation and post-frac production analysis have confirmed that initial
hydrocarbon production and ultimate recovery in reservoirs are mainly associated with the …

This paper presents a general overview of hydraulic fracturing models developed and
applied to simulation of complex fractures in naturally fractured shale reservoirs. It discusses …

This paper presents an integrated methodology that utilizes the cohesive zone model (CZM)
to simulate propagation of hydraulic fractures, and their interactions with pre-existing natural …
