Texas A&M University (TAMU) (also known as Texas Engineering Experimentation Station [TEES]) proposes to use American Recovery and Reinvestment Act funds to develop a framework for investigating processes that contribute to the occurrence of seismicity in enhanced geothermal systems. TAMU/TEES would use an integrated geological and geomechanical approach to identify the causal mechanisms of micro-earthquakes (MEQs), and to relate their occurrence to the resulting changes in rock mass characteristics. To complete this project, TAMU would conduct a combination of information gathering and dissemination, analysis of a sample collection from new and preexisting field demonstration projects, and laboratory experimentation/analysis on the collected raw data.
