Paper presented at the 54th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2020
Paper Number: ARMA-2020-1595
... ABSTRACT Induced seismicity related to oil and gas activity has been observed at many fields in recent years. Improving understanding of geomechanical factors leading to fault reactivation can help in assessment of this hazard. The present study analyzes fault reactivation due to injection...

Our model is based on elasticity theory, and we use finite element methods or boundary element methods for our solutions. The displacement along the fault faces causes strain, which is dispersed to other...
