The most common fallacy in the quest for the optimum stimulation treatment in shale plays
across the country is to treat them all just like the Barnett Shale. There is no doubt that the …

Acoustic logging is a multidisciplinary technology involving basic theory, instrumentation,
and data processing/interpretation methodologies. The advancement of the technology now …

Mudrocks, defined to be fine‐grained siliclastic sedimentary rocks such as siltstones,
claystones, mudstones and shales, are often anisotropic due to lamination and microscopic …

In unconventional reservoirs, stress models that account for anisotropy yield a stress profile
which better represents in-situ conditions than the profile suggested by an isotropic stress …

A novel correlation identifying inefficient drilling conditions is presented using experimental
and field data. Historically, Mechanical Specific Energy (MSE) has been used to improve the …

Shale formations are the main source of borehole stability problems during drilling
operations. Suboptimal predictions of borehole failure may partly be caused by neglecting …

Near-wellbore alteration in shear stiffnesses in the three orthogonal planes can be
described in terms of radial variations of the three shear moduli or slownesses. The three …

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 …

Heterogeneity and anisotropy were characterized in some Eagle Ford shale samples at
various scales by use of scanning-electron-microscopy (SEM) imaging, computed …

A finite-difference time-domain (FDTD) formulation with perfectly matched layer (PML)
enables analysis of elastic-wave propagation in a fluid-filled borehole in an arbitrarily …
