.... In the end, we offer suggestions on how to couple the hydromechanical processes in order to evaluate the possibility of fault reactivation. 1 INTRODUCTION 1.1 Generalities The presence of faults is expected to affect the flow of fluids through areas of the reservoir and to have an effect...

... ABSTRACT: The reactivation of geological faults in oil and gas reservoirs during the production process may lead to severe consequences. During fluid injection, the stress state of the surrounding formation is modified, which may induce slippage, seismicity and breach of the reservoir seal...

... Abstract As mining operations go deeper, along with an increase of on-situ stresses, faults may be reactivated and seismic events may be induced. This paper describes several cases of mining induced seismic events and focuses on the strength of faults. From stress analyses it is known...
