Engineers and geologists in the petroleum industry will find Petroleum Related Rock
Mechanics, 2e, a powerful resource in providing a basis of rock mechanical knowledge-a …

We present a rigorous validation of the analytical Amadei solution for the stress
concentration around an arbitrarily orientated borehole in general anisotropic elastic media …

We develop a methodology to model and interpret borehole dipole sonic anisotropy related
to the effect of geologic fractures, using a forward-modeling approach. We use a classical …

Production of hydrocarbon causes changes in pore pressure and effective stresses acting
on the reservoir rocks. This will be followed by reservoir compaction, surface subsidence …

Stress dependency and anisotropy of dynamic elastic properties of shales is important for a
number of geophysical applications, including seismic interpretation, fluid identification, and …

The generation of a fracture network in reservoir rocks for fluids to flow via hydraulic
fracturing is important in shale oil and gas development, and the intersection between …

Formation properties near a borehole are frequently altered by mechanical damage from
drilling, leading to variations of formation elastic velocities in the radial direction. Inversions …

Borehole sonic measurements are routinely used to measure dynamic elastic properties of
rock formations surrounding a wellbore. However, shoulder-bed effects, mud-filtrate …

Shale gas formations exhibit strong mechanical and strength anisotropies. Thus, it is
necessary to study the effect of anisotropy on the hydraulic fracture initiation pressure. The …

One of the major challenges in the interpretation of sonic logs is the presence of bed-
boundary (shoulder-bed) effects, which can decrease the accuracy of the estimated elastic …
