... preexisting and induced fractures. A better understanding of fracture slip in granite during fluid injection is critical to optimize the strategies of hydraulic stimulation. We experimentally investigated the shear behaviors of a sawcut fracture, a gouge-filled fracture, and a natural fracture in Bukit Timah...

... whether the subsequent crack can be cracked. Using finite element method based on the poroelastic theory, we can get the production induced stress field. Before that, reservoir's geometrical model was built with DNF (discrete natural fractures), employing crack propagation simulation results to get the...

... Abstract The complex interaction between hydraulic and natural fracture was believed to have a significant impact on hydraulic fracture complexity. Extensive theoretical and experimental works had proved this interaction was affected by several parameters, such as stress difference...

... increase consistently with depth, but rather scatter quite significantly. It is observed that near the depths of relatively low stress, natural fractures and faults with wide apertures (possibly weak friction) are abundant, and near those of relatively high stress, those wide discontinuities are scarce. In...

... Abstract To investigate the natural fracture's effect on hydraulic fracturing crack propagation in the coal seam, the two-dimensional model of hydraulic fracturing crack intersecting natural fractures is built. Based on it, the laws of crack propagation and failure mechanism of natural...

... ABSTRACT Hydraulic Fracturing has been used successfully in the oil and gas industry to enhance oil and gas production in the past few decades. Recent years have seen the great development of tight gas, coal bed methane and shale gas. Natural fractures are believed to play an important role in...

... importance of natural fractures, and describes what challenges are encountered during drilling, completion, and development of tight reservoirs. Then we discuss the related geomechanics and how it adds value for the development of tight gas reservoirs. 2. DEFINITIONS Tight formation gas is natural gas...
