Role of molecular diffusion in heterogeneous, naturally fractured shale reservoirs during CO2 huff-n-puff

TLDR
Findings in this work reveal the importance of the configuration of the pre-existing natural fracture system for the performance of the huff-n-puff process and a threshold correlation length value wherein heterogeneity becomes favorable for improved oil recovery instead of hampering oil recovery.
