Abstract: A three-dimensional, transversely isotropic yield condition is combined with a plane of weakness to describe the initial yield limit for Green River Shale. This theory is compared to experimental ...

Abstract: The purpose of this paper is to report the results of finite element analyses of the collapse of perforated casing. In the study, both inline (0-deg phasing) and staggered (90-deg phasing) ...

Abstract: The effect of formation anisotropy on the hole deviation force acting on a single bit tooth is analyzed for a plastically deforming rock. A yield condition which allows a nonlinear dependence ...

Abstract: A small-scale, shallow experiment was conducted by Amoco Production Research, Sandia Laboratories, and the U. S. Geological Survey, in order to study the potential of several geophysical monitoring ...
