Abstract

Geothermal resources in low-permeability and medium-to-high temperature reservoirs in sedimentary sequence require hydraulic stimulation. However, hydrothermal fluid migration for geothermal energy use in enhanced geothermal systems (EGS) is dependent on the in-situ flow pathway network created by induced hydraulic fractures. Also, there is still no comprehensive knowledge on the impact of geomechanical alterations on the hydrothermal fluid migration in EGS. This study presents a systematic review of the effects of changes in mechanical properties on the fracture behavior and fracture pathway created for efficient extraction of heat in EGS reservoir. This review will contribute to the state-of-knowledge on the impact of geomechanics on fractomechanical behavior in EGS.
