NMR-Based Analysis of Fluid Occurrence Space and Imbibition Oil Recovery in Gulong Shale
Processes, 2023 The Gulong shale oil reservoir is formed in freshwater to slightly saline lacustrine basins, mainly consisting of pure shale geological structure, which is quite different from other shale reservoirs around the world. Currently, the development of Gulong shale oil mainly relies on hydraulic fracturing, while the subsequent shut-in period for imbibition

Effect of reservoir heterogeneity on CO2 flooding in tight oil reservoirs [PDF]
, 2022 Carbon dioxide (CO2)-enhanced oil recovery (EOR) has great potential and opportunity for further development, and it is one of the vital carbon capture, utilization, and storage (CCUS) technologies.

A comprehensive review on shale studies with emphasis on nuclear magnetic resonance (NMR) technique [PDF]
, 2023 Multi-scale shale studies put a significant emphasis on high-resolution investigations from nanometer to decametre scales. Despite that multiple advanced techniques have been used in shale studies, they are mostly limited to the detection scopes and have

Molecular simulation of adsorption behaviors of methane and carbon dioxide on typical clay minerals [PDF]
, 2023 Knowledge of the interaction mechanisms between shale and CH4/CO2 is crucial for the implementation of CO2 sequestration with enhanced CH4 recovery (CS-EGR) in shale reservoir. As one of the main constituents of shale, clay minerals can profoundly affect
