FreeUSP Code Base
In 2001, BP open sourced the bulk of the Unix Seismic Processing system (USP) as FreeUSP.
USP has a rich history, involving many scientists research efforts, and we encourage you to read "A Short History of USP".
Over the span of our careers at Amoco, BP and now at OpenGeoSolutions, we have used, developed and supported the USP software.... and trained people in the use, development, and support of USP.
OpenGeoSolutions OpenSEIStm proprietary software is built upon and extends the FreeUSP code base.
