Pore and fracture scale characterization of oil shale at different microwave temperatures [PDF]

Oil Shale, 2023
The spatial complexity of oil shale systems is manifested by microstructure, pore space randomness and extensive heterogeneity. A microwave pyrolysis device developed for this study was used to pyrolyze oil shale, and the microstructure before and after ...

Digital core reconstruction research: challenges and prospects

Geology, Ecology, and Landscapes, 2022
In this review we have briefly reviewed the state of the art of “digital core” technology. In particular, we reviewed the main artefacts that can occur in the analysis of rocks by computed X-ray microtomography.

Lattice Boltzmann modeling of the coupled imbibition-flowback behavior in a 3D shale pore structure under reservoir condition

Frontiers in Earth Science, 2023
Imbibition and flowback of fracturing fluid usually occur in the shale matrix after hydraulic fracturing, which significantly impacts shale gas production and environmental protection. The rocks of deep shale gas reservoirs are under high-temperature and
