A spectral boundary-integral method for faults and fractures in a poroelastic solid: Simulations of a rate-and-state fault with dilatancy, compaction, and fluid injection

Abstract

We present a novel spectral boundary-integral method (SBIM) for a 2D poroelastic solid• We solve for fault slip with fully-coupled dilatancy and injection on a rate-andstate fault• The method is applied to study the influence of several parameters on fault stability
