Fault Slip Potential (FSP) is a free tool for deterministic and probabilistic screening of the rupture stability of existing faults in contact with a reservoir undergoing a pore pressure change, typically near injection wells. The tool can be used for screening of individual faults locally, or systems of faults regionally. The tool combines Mohr-Coulomb analysis with pore pressure modeling. FSP can use either an imported pressure model or semi-analytic pressure modeling of a uniform confined aquifer using constant, isotropic parameters and linear superposition of multiple wells. It can also be used to assess the rupture stability of faults in the natural state or as influenced by uniformly perturbed conditions. Faults are assumed to be in contact with the injection interval and out-of-zone effects and poroelasticity are not considered. FSP is best used in conjunction with a GIS tool such as ArcMap and a tutorial for that I/O process is provided.
FSP was developed and publicly released in 2017 through a partnership between ExxonMobil and the Stanford Center for Induced and Triggered Seismicity (https://scits.stanford.edu/). In 2023 the role of provision, maintenance and feature enhancement was transferred to The University of Texas Bureau of Economic Geology and the Center for Injection and Seismicity Research and the TexNet Seismological Network (https://www.beg.utexas.edu/texnet-cisr).
