Fault Slip Potential (FSP)
Fault Slip Potential (FSP) is a free software tool for probabilistically screening faults near injection wells. The program was created by the Stanford Center for Induced and Triggered Seismicity through industry-academic collaboration.
Beginning September 1, 2023, the FSP software and related information and tutorials have been transferred from Stanford to the Center for Injection and Seismicity Research (CISR) of the University of Texas, Austin.
To download the FSP software, and its associated files, please visit the CISR FSP website. Information about changes to the software, new versions, and associated information will be available through CISR.
