.... Natural layer-parallel slip is facilitated by higher bedding dips in a fold where layer-parallel shortening occurs. But an uncertainty still remains whether fluid can be injected into sub-horizontal bedding-planes, in a normal or strike-slip regional stress field, as found in North America, where...

... Abstract The objective of this paper is to incorporate multi-weakness plane failure into a new anisotropic wellbore stability model for transversely isotropic rock media involving naturally fractured and foliated formations. The model provides a good prediction of wellbore failure, safety...

... Abstract Shale formations have laminated structures which result in significant differences in mechanical properties along the orientations parallel to and perpendicular to laminations (bedding planes). These differences lead to anisotropic horizontal stresses. Failure to consider the effect...

... ratios (SORs) and lower production rates. A vertical single-well injector/producer was proposed that consists of six vertical propped planes installed at varying azimuths from the bottom to the top of the pay. Steam would be injected at the top of the pay, and liquids would be extracted at the bottom...

... Abstract Microseismic monitoring of hydraulic fracture stimulation is used to map the extent of fracture growth during the completion of unconventional resource wells. Usually the geometry of the event distributions is used to infer fracture plane orientations, for instance when microseismic...
