The loading path the fault experiences is often neglected when evaluating its potential for reactivation and related seismic risk. However, stress history affects zone compaction dilation, thus mechanics. Therefore, in incohesive cores that could dilate or compact, role of not be ruled out. Here we reproduce laboratory different tectonic paths reverse (load-strengthening absence significant flu...

Abstract Because of the special geographical location adjacent to Tibetan Plateau, geological setting Sichuan Basin is very complex, which brings a great challenge shale gas development. In this study, we conducted an integrated microseismic and geomechanical analysis on refracturing well in Basin. We observed that casing deformation occurred area fault reactivation. However, reactivation pre-e...

Slip-tendency analysis is a valuable tool in fault reactivation evaluation and seismic hazard assessment as it provides a means of quantifying the slip potential on mapped or suspected faults in a known or inferred stress field. We developed an interactive graphic tool to perform slip-tendency analysis. The application is written in MATLAB in the form of plug-ins for COULOMB, a graphic-rich def...

Oblique subduction at a high rate of convergence along much of the Middle America Trench results in northwest-directed trench-parallel block motion. Accommodation of this motion along northwest-striking dextral strike-slip faults has been postulated; however, in Nicaragua such faults are not well developed. We suggest instead that this motion is accommodated by bookshelf faulting that includes ...

Abstract We consider the implications of adding a cap to yield surface for elastic–plastic and elastic–visco-plastic solids with coupling between deformation, fluid flow mineral reactions. For suitable combination (low) permeability strain rate, opening-mode veins can form in compression. Such behaviour is enhanced by dissolution simultaneous reactions negative ΔV. These are equivalents compact...
