... orthotropic elasticity. The equations are developed based on simple laboratory testing configurations. The development of the three-dimensional equations of orthotropy is given in this paper. The method is validated with a numerical example and applied to a data set of test results performed on SURF rock...

... Abstract Sand production is a complex phenomenon in oil wells where sand grains or chunks are detached from the formation during loading processes and transported to the wellbore by the flowing fluids, either oil, water or gas. This article presents a complete set of different laboratory tests...

... with estimation of strength using these schemes are high and strength estimates need to be treated with caution. Undertaking point load index testing in the field is a useful tool that can provide data to augment field strength estimates and laboratory test data. Field point load index test data can be converted...

... Abstract The laboratory testing described here can be seen as the first step in investigating potential thermal effects leading to the creation of a leakage pathway at or in the vicinity of a CO 2 injection well. The occurrence of thermal stresses in metal casing, cement and formation can...

... Abstract: The suitability of hybrid 2D-FEM/DEM methods for simulating brittle failure laboratory testing has been described by numerous researchers emphasizing their ability to illustrate clearly the transition from an intact rock continuum to a discontinuum fractured state. However...

... a mixture of clay and rock fragments of various sizes is collected, and it is therefore very difficult to obtain usable undisturbed samples of gouge material from a weakness zone for laboratory testing. In Norway, a laboratory test method based on measuring the swelling pressure of remoulded specimens has...

... ABSTRACT The proposed research and development program to advance disposal concepts for heat-generating waste in salt comprises four general initiatives: Laboratory Testing, Modeling and Simulations, Workshops and International Collaborations, and Field Testing. In a chronologic sense, some...

... by the rise rate of the backfill in the stope. The time-dependent behavior of the fill is implemented as each layer can be aged and assigned the age appropriate material properties. These properties were obtained by a laboratory testing program summarized in the paper. The paper presents a brief validation...

... of geomechanics in order to assist in the interpretation and prediction of results. The bending and the double-sided shear tests are the two laboratory tests that are designed to evaluate the properties of different TSLs. This paper evaluates the use of numerical modeling to simulate the material properties...
