Synchrotron X-ray tomographic characterization of microstructural evolution in coal due to supercritical CO2 injection at in-situ conditions
Guanglei Zhang,Pathegama Gamage Ranjith,Bisheng Wu,Mandadige Samintha Anne Perera,Mandadige Samintha Anne Perera,Asadul Haque,Dongyin Li +6 more
TL;DR: In this article, the authors performed CT imaging under simulated reservoir conditions with a novel X-ray transparent core holder and investigated the time-dependent evolution of 3-D microstructures of an anthracite coal with 1.37% moisture as-received interacted with supercritical CO2 (ScCO2).
