There is a quite the story being written today about the ways geothermal energy can help transition an existing oil and gas field into an electricity-generating system. SMU has been leading the research, development and promotion of such a concept for over two decades.
The following is a summarized timeline, featuring historical developments that have helped advance geothermal proof of concepts within O&G fields throughout the US.
1975: Texas Geothermal Resources Act written
1989: First Geopressure power plant in the US, Brazoria County, TX
1992: SMU completes first Geothermal Map of North America
