Terence P. O'Sullivan is a petrophysicist with more than forty years of worldwide exploration and development experience, including oil, gas and geothermal reservoir characterization.
From 1997 to 2017 his focus was on heavy oil reservoirs in California. With thousands of closely-space wells, thermal development projects provided a unique opportunity to develop new technologies for observation of steam during the heavy oil recovery process, resulting in more than 10 publications and several patents.
The patent for transient high gamma ray provides an exciting opportunity to reconnect with geothermal, 40 years after working at the USGS, while characterizing fracture response at the Raft River geothermal reservoir.
