Numerical analyses of the long term behavior of enhanced geothermal system (EGS)
Enhanced Geothermal System (EGS) technology is a challenging extrapolation of conventional hydrothermal geothermal systems but expected to significantly contribute to U.S. energy in near future. This technology is still going through a steep learning phase and current research studies are mostly …

Understanding the Relationship between Hydraulic Properties of Rocks and Induced Seismicity in the Stimulation of Enhanced Geothermal Systems
… of numerical models to gain insight on Enhanced Geothermal System (EGS) stimulation operations. These operations consist of high pressure injection of cold water in low permeability formations at depth of 2-4 kilometres, promoting the opening of existing fractures and creating an …

Imaging the Soultz Enhanced Geothermal Reservoir using double-difference tomography and microseismic data
… velocity structure of the European Hot Dry Rock geothermal reservoir (also known as the Soultz Enhanced Geothermal System) at Soultz-sous-Forets, France. We used absolute, differential catalog and differential cross-correlation times obtained from the reservoir's September and October 1993 …

Effects of thermally-induced fractures on EGS performance
An Enhanced (or Engineered) Geothermal System (EGS) is defined as an engineered reservoir formed by hydro-fracturing hot dry rock to extract heat from low permeability geothermal resources to generate electricity. EGS technology is undergoing stages of advancement, and a substantial amount of …
