... 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...

...-bore integrity, existing fault reactivation and potential notable seismic events, have received increasing attention from researchers, policy-makers and the general public. In order to address these challenges, many analytical methods, including analytical analyses, numerical modeling and response...

... of reactivation and possible loss of tightness of the reservoir. Thus, the aim of this study was assess reservoir models with a fault zone using partially coupled hydro-mechanical simulations. The methodology considers a fault zone whose behavior is given by the Mohr-Coulomb yield criterion. The plasticity model...

... 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...
