Understanding the effects of mineral composition on geomechanical characteristics is critical
in order to design and optimize the hydraulic fracturing necessary for shale gas reservoir …

Frequently, shales are treated as isotropic formations. However, organic rich shales are
anisotropic due to their laminated structure and chemical properties. In this study, shale …

Tight oil is a great potential resource for unconventional oil exploration and development.
Determining the content of adsorbed tight oil in sandstone reservoirs and the factors …

Drilling through chemically-active shale formations is of special importance due to time-
dependent drilling fluid–shale interactions. The physical models presented so far include …

A nonlinear generalized multiple moving boundary model of one-dimensional non-Darcy
flow in heterogeneous multilayered low-permeability porous media with a threshold …

Abstract Oil and Gas Shales are becoming major contributors to the daily crude output in the
global energy market. Due to permeability concerns, they require hydraulic fracturing to be …

Unconventional geomechanics has attracted research interests in shale gas development,
owing to the potential to mitigate drilling risk and optimize hydraulic fracturing. In the …

The interaction between shale bedding planes and fluids significantly weakens their
structural integrity, profoundly affecting borehole stability in shale reservoirs. However …

Among the several problems encountered in drilling, wellbore instability has been regarded
as the most adverse and the problem becomes more peculiar when the drilled formation is …

Anisotropic strata are frequently encountered in deep drilling engineering, especially for the
rock with fracture structures. The problem of instability in highly deviated well in this kind of …
