In-situ thermal upgrading is used to tune the pore system in low-maturity oil shales. We introduce fractal dimension (D), form factor (ff) and stochastic entropy (H) quantify heating-induced evolution of morphological complexity azimuthal disorder develop a model estimate impact on seepage capacity via permeability. Experiments are conducted under recreated in-situ temperatures consider anisotropic properties - both parallel perpendicular bedding. Results indicate that distribution pores...
Because of the complex nature coal reservoirs, no determined method can clearly assess their pore–fracture structure. This paper combines a fractal with transverse relaxation time (T2) nuclear magnetic resonance (NMR) to study pore–fractures in reservoir. Based on 10 samples vitrinite reflectance (Ro,m) range 1.32–2.43%, pore size/volume distribution from mercury intrusion porosity (MIP) and NMR was compared, revealing that strong correspondence exists, for diameter >100 nm is better than...
Canopy effect in this paper refers to the phenomenon whereby moisture accumulates underneath an impervious cover. Field observations reveal that canopy can occur relatively dry soils where groundwater table is deep and lead full saturation of soil immediately However, numerical analysis based on existing theories heat mass transfer unsaturated only reproduce a minor amount accumulation caused by cover, particularly when deep. In attempt explain observed field, proposes new mechanism freezing...
