... ABSTRACT: In most instances of the application of rock mechanics to oilfield problems the loading on the rock can be regarded as static or quasi-static. Furthermore the rock mechanical parameters that are used to quantify the rock response are obtained from static or quasi-static laboratory...

... ABSTRACT: Sandia's GeoModel is a generalized plasticity model that was developed primarily for geological materials, but is also applicable to a much broader class of materials such as concretes, ceramics, and even some metals. Nonlinear elasticity has been incorporated through empirically...

... ABSTRACT: Leak off tests are routinely performed by the drilling industry and have been used for many applications including the determination of cement integrity, mud weight limit for the next hole section, and the estimation of minimum horizontal stress. The potential of these tests...

... ABSTRACT: This article demonstrates the effects of regional hard rock mining in several case studies of shallow stope cave-in failures. Applicable numerical modeling methods indicate that destressing of the rock mass is in effect under such extensive mining, which facilitates the occurrence...

... ABSTRACT: The discipline of geomechanics is gaining greater recognition in the petroleum industry worldwide. One reason is application of geomechanics is producing significant financial benefits to drilling operations from exploration to field development. Continued success will require...
