Hydraulic fracturing under high temperature and pressure conditions with micro CT applications: Geothermal energy from hot dry rocks
W.G.P. Kumari,Pathegama Gamage Ranjith,Mandadige Samintha Anne Perera,Mandadige Samintha Anne Perera,Li Xueqin,Linge Li,Bernard Chen,B.L. Avanthi Isaka,V.R.S. De Silva +8 more
TL;DR: In this article, the authors investigated the effect of reservoir depth, temperature, and sample heterogeneity during hydraulic fracturing and the influences of rock micro-structure on fracture propagation in deep geothermal reservoirs.

TL;DR: In this paper, the authors investigated the influence of temperature on tensile strength of Australian granite granites, including Strathbogie and Harcourt, and found that higher temperatures resulted in a considerable crack closure and an increase in the unstable crack propagation.

The use of super-critical carbon dioxide as the working fluid in enhanced geothermal systems (EGSs): A review study
TL;DR: In this paper, the applicability of supercritical carbon dioxide (ScCO2) as the working fluid in enhanced geothermal systems (EGSs) by replacing water was recently investigated by research studies due to a number of advantages accompanied in CO2 as working fluid.

Influence of long-term operation of supercritical carbon dioxide based enhanced geothermal system on mineralogical and microstructurally-induced mechanical alteration of surrounding rock mass
B.L. Avanthi Isaka,Pathegama Gamage Ranjith,Tharaka Dilanka Rathnaweera,Tharaka Dilanka Rathnaweera,Mandadige Samintha Anne Perera,Mandadige Samintha Anne Perera,W.G.P. Kumari +6 more
TL;DR: In this paper, a series of uniaxial compressive and triaxial (under 30MPa constant confining pressure with different temperatures; 25-300°C) strength tests on granite specimens reacted in ScCO2+water medium for different time periods was performed by coupling acoustic emission (AE) technique.
