Fault Slip Potential

Background

Fault Slip Potential (FSP) is a simple screening tool for estimating the probability of injection-related seismicity using a combination of Mohr-Coulomb analysis, pore pressure modeling, and Monte Carlo parameter sampling. FSP uses either an imported pressure model or semi-analytic pressure modeling of a uniform confined aquifer with constant, isotropic properties and assumes a linear superposition of multiple wells. Faults and any seismicity are assumed to be in the injection interval.

FSP was originally developed and publicly released in 2017 by the Stanford Center for Induced and Triggered Seismicity (https://scits.stanford.edu/). FSP has since moved to the Bureau of Economic Geology at the University of Texas at Austin. In 2025 TexNet and ExxonMobil released FSP 3.0 as an open-source web-based tool.

 

The current version of the Fault Slip Potential Tool (v3.1) is available through the TexNet Software Portal.
