... Abstract In laboratory experiments, an evolution of the measured rock properties is often observed when the core undergoes cyclic solicitations. There is still a debate in order to define which value should be chosen, and basically the question is to define which value is intrinsic to the rock...

... Abstract Hydrostatic and triaxial compression experiments have been conducted to investigate the evolution of fluid permeability and fluid storage capacity in Tennessee sandstone, a low- porosity tight' reservoir sandstone. A newly developed single-ended transient pulse permeability...

... Abstract In order to get a realistic prediction of the in situ stress evolution, compaction and subsidence of the HP/MT Shearwater field, full 3-D finite element calculations were made with the program DIANA. An interface was made to generate 3-D meshes directly from seismic files, which led...

... pressure is low. Concerning fracture initiation pressure, the tangential stress evolution is also strongly controlled by heat convection. The temperature decrease (cooling) induces a significant and time dependent tensile tangential stress zone where the breakdown pressure may be much smaller than...

... Abstract We report results from laboratory triaxial deformation experiments on sandstone specimens containing pore fluid in which the evolution of microcrack damage was continuously monitored by acoustic emission (AE) output. We use the AE output to calculate the evolution of mean strain energy...

... Abstract The density of the drilling fluid and its chemical composition are the main operational parameters controlling the stability of wellbores drilled in shales. To quantify their impact on the stress evolution around wellbores in pervious shales, we have developed a model that accounts...
