Drilling through reactive shale formations is normally associated with borehole instability
and is a problem the petroleum industry continues to face every day, with enormous losses …

This paper presents closed-form solutions for the pore pressures and stress fields for the
inclined borehole and the cylinder, induced by boundary stress perturbation in an …

Shale gas formations are typically characterized by anisotropic and fracture properties.
Existing shale wellbore stability models have only considered the anisotropy of shale rocks …

This paper presents a numerical solution of dual-porosity poroelastic formulations that
couple solid deformations with fluid flow in both matrix and fracture systems of naturally …

This book covers fundamental principles and analytical and numerical approaches that may
be applied in representing the coupled interaction of deformation, flow, and transport in …

As the main hydrocarbon reservoirs, sedimentary formations are usually anisotropic in
elasticity, strength, and permeability. Traditional wellbore stability analysis assumes that the …

Functions as a self-study guide for engineers and as a textbook for nonengineering students
and engineering students, emphasizing generic forms of differential equations, applying …

This paper presents a multiscale analysis of the classical borehole instability problem in
high‐porosity sandstones using a hierarchical multiscale approach. A rigorous, two‐way …

Tight gas reservoirs are typically characterized by the unsaturated case that contains both
water and gas fluids. However, previous wellbore stability analysis usually assumes that the …

Existing porothermoelastic models assume that shale is isotropic and disregard material
anisotropy. When material anisotropy is considered, the shale-bedding plane must be …
