Abstract The temperature gradient between the geological formation and the injected supercritical CO2 (Sc-CO2) initiates heat transfer processes, leading to a non-uniform temperature field within the fracture. This spatial thermal variation induces fluctuations in the density and viscosity of Sc-CO2. Moreover, the non-uniform density distribution of Sc-CO2 leads to varying degrees of volume expansion or shrinkage, influencing fluid flow velocities within the fractures. This study integrates heat transfer and fluid leak-off models into the Eulerian-Eulerian two-fluid framework to systematically investigate the collective impacts of Sc-CO2's density, viscosity, and density-induced volumetric alterations on the proppant transport process under varied pumping… More >
