Abstract Knowledge of accurate rock strength is essential for in situ stress estimation,
wellbore stability analysis, sand production prediction and other geomechanical …

Several studies have been done about borehole stability and optimized wellbore direction.
However, the majority of them focused on stability during drilling, and there are only a few …

A key component to success with low-permeability, organic-rich rock resource plays is
targeting rocks that contain natural fractures or that can be effectively hydraulically …

Oil and gas production and the related deformation of reservoir formations are typical
examples of multi-physics phenomena existing in engineering. Liquid, gas, and solid …

Wellbore instability is one of the most critical challenges affecting drilling and production.
Borehole instability in both shale and sand formations, hole collapse, lost circulation, stuck …

Reservoir depletion will cause in-situ stress reductions in both reservoir and overburden
(caprock) sections. Horizontal and vertical stresses will also be affected by the depletion …
