...1 INTRODUCTION Induced stress change during fluid production from hydrocarbon reservoirs, and fluid injection for en- hanced oil recovery or greenhouse gas sequestration, may lead to rock deformation, induced fracturing and fault reactivation, and consequently major risks such as ground movement...

... ABSTRACT ABSTRACT: Trials were undertaken in a narrow-vein mine of Northern Quebec, Canada, to monitor stress changes in sill pillars due to mining. Trials were carried out in active mine areas using vibrating wire proving rings and short extensometers, installed in boreholes to monitor radial...

... in quality (9 out 12). Even with struc- tures present or developed in a poor rock mass, ex- cavations in these cases were stable until disturbed by external factors such as geometry change, stress change, mining disturbance or seismicity. This im- plies that rock mass quality and structural effects...

... or geological storage projects, it is critical to assess the reactivation tendencies of existing faults and fractures. In this paper a poroelastic, semianalytical model for predicting induced stress changes is summarized, and a methodology to assess fault reactivation tendency based on the Coulomb Failure...

...1 INTRODUCTION Coulomb stress triggering in earthquake mechanics is concerned with quantifying stress changes along crustal faults, due to stress changes caused by histor- ical earthquakes. This should lead to an advance or delay in time of future earthquakes, either on the same fault or other...
