Paper Number: ARMA-2018-745
... ABSTRACT: In deep underground mining, fault slip and associated rockbursting present a significant hazard to the safety of personnel, equipment and mine infrastructure. Recently, hydraulic injection has been proposed as a method of mitigating fault slip risk as it has the potential to trigger...
Paper presented at the ISRM European Rock Mechanics Symposium - EUROCK 2018, May 22–26, 2018
Paper Number: ISRM-EUROCK-2018-069
... ABSTRACT In present paper authors examine the conditions for which the fault motion exhibits stick-slip like dynamics, under the main assumption that a fault filling at least along a certain part of the fault possesses viscous properties. Analysis is conducted for the mechanical spring-block...

... Abstract Recovery of bypassed oil banked against non-conductive faults in heavily-faulted and stress-sensitive reservoirs such as the Wilmington and Kern River fields of California can raise concerns of fault destabilization. Here, we investigate the effects of well configuration and well flow...
