Paper presented at the ISRM European Rock Mechanics Symposium - EUROCK 2017, June 20–22, 2017
Paper Number: ISRM-EUROCK-2017-104
... Abstract The current study presents a numerical modeling approach for three-dimensional simulation of hydro-shearing in jointed rocks for the generation of a man-made, multi-fracture heat exchanger in Hot Dry Rock (HDR) Geothermal reservoir. Various literatures have suggested the presence of...

... Geological Survey of Japan, AIST, Tsukuba, Ibaraki, Japan ABSTRACT: Hydraulic-mechanical (HM) processes including fracture propagation in geomaterials are impor- tant factors for many geo-environmental issues. A coupled HM simulation tool, TOUGH-RBSN, has been developed to investigate permeability change of...

... during cutting that causes the wear of the bit. Numerical models of the Automated Rock and Coal Cutting Simulator (ARCCS) were developed using the ABAQUS. Two bit designs K-1M and K-2M were analyzed numerically and it was found that the effect of heat developed on the bit not only depends on the friction...

... integrity of an oil well, employing partially coupled fluid-mechanical simulations. The Namorado Field (Campos Basin, Brazil) was adopted in this study as a black-oil model. Since the geomechanical effects were obtained in the reservoir scale, a special workflow had to be followed in order to obtain the...

... reactivation and possible loss of tightness of the reservoir. Thus, the aim of this study was assess reservoir models with a fault zone using partially coupled hydro-mechanical simulations. The methodology considers a fault zone whose behavior is given by the Mohr-Coulomb yield criterion. The plasticity model...

... ABSTRACT The behavior of a specimen under uniaxial tension and the process of microfracture in such a specimen are phenomena of considerable interest from the point of view of understanding strength charaterization of rock. We present numerical results, based on A simulator named Rock Failure...
