Opportunities and Challenges in Deep Mining: A Brief Review
Pathegama Gamage Ranjith,Jian Zhao,Minghe Ju,Radhika V.S. De Silva,Tharaka Dilanka Rathnaweera,Adheesha K.M.S. Bandara +5 more
TL;DR: In this paper, the authors present the current global status of deep mining and highlight some of the newest technological achievements and opportunities associated with rock mechanics and geotechnical engineering in deep mining.
Journal ArticleDOI
Mechanical behaviour of Australian Strathbogie granite under in-situ stress and temperature conditions: An application to geothermal energy extraction
W.G.P. Kumari,Pathegama Gamage Ranjith,Mandadige Samintha Anne Perera,Shi Shi Shao,Bernard Chen,Aref Lashin,N. Al Arifi,Tharaka Dilanka Rathnaweera +7 more
TL;DR: In this paper, the authors investigated the stress-strain behavior under in-situ stress and temperature conditions by conducting a series of high-pressure, high-temperature triaxial experiments on Australian Strathbogie granite under four different confining pressures (10, 30, 60, 90 MPa) and four different temperatures (RT, 100, 200, 300 °C).
Journal ArticleDOI
A Review of CO2-Enhanced Oil Recovery with a Simulated Sensitivity Analysis
Mandadige Samintha Anne Perera,Ranjith Pathegama Gamage,Tharaka Dilanka Rathnaweera,A.S. Ranathunga,Andrew Koay,Xavier Choi +5 more
TL;DR: In this paper, a comprehensive study of the CO2-EOR (Enhanced oil recovery) process, a detailed literature review and a numerical modelling study are presented. And a 3-D numerical model was developed using the CO 2-Prophet simulator to examine the effective factors in the Co2EOR process, which can be used to enhance the two major oil recovery mechanisms.
Journal ArticleDOI
Experimental investigation of thermomechanical behaviour of clay-rich sandstone at extreme temperatures followed by cooling treatments
Tharaka Dilanka Rathnaweera,Pathegama Gamage Ranjith,X. Gu,Mandadige Samintha Anne Perera,Mandadige Samintha Anne Perera,W.G.P. Kumari,W.A.M. Wanniarachchi,Asadul Haque,Jianchun Li +8 more
TL;DR: In this article, the authors investigated the influence of extreme temperatures (from 25° to 1000°C) followed by two cooling methods (both rapid and slow) on the mechanical behaviour of clay-rich Hawkesbury sandstone under uniaxial conditions.
Journal ArticleDOI
CH4–CO2 gas exchange and supercritical CO2 based hydraulic fracturing as CBM production-accelerating techniques: A review
K.H.S.M. Sampath,Mandadige Samintha Anne Perera,Pathegama Gamage Ranjith,Stephan Matthäi,Tharaka Dilanka Rathnaweera,Guanglei Zhang,X. Tao +6 more
TL;DR: In this paper, a comprehensive overview of the CH4 CO2 gas exchange method at macro and microscopic level, and the CO2-based hydraulic fracturing is comprehensively discussed considering two possible CBM storage mechanisms; 1) by adsorption and; 2) at hydrate state.
