EFFECT OF RESERVOIR PROPERTIES ON THE PERFORMANCE OF OIL SHALE IN-SITU PYROLYSIS USING SUPERCRITICAL CO2 IN FRACTURED RESERVOIR

ABSTRACT
This study conducted simulations to investigate the heat transfer dynamics of su­percritical CO2 as a thermal carrier within oil shale formations. The paper aimed to elucidate the impact of formation physical properties on the pyrolysis efficiency of oil shale. The findings from the simulations indicate that porosity minimally affects the thermal sweep but is directly correlated with the heating pore area. Meanwhile, permeability significantly influences both porosity and the extent of pyrolysis sweep, suggesting the preferential selection of formations characterized by high initial porosity and permeability wherever feasible.
