Paper presented at the 55th U.S. Rock Mechanics/Geomechanics Symposium, June 18–25, 2021
Paper Number: ARMA-2021-1622
... ABSTRACT: Shallow and deep geothermal reservoirs are potential renewable energy sources. Heat extraction from geothermal reservoirs disrupts the natural temperature gradient and causes thermo-poro-elastic effects both in the reservoir and overlying formations. The drained thermo-elastic...
