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

Characterization of Flow Parameters in Shale Nano-Porous Media Using Pore Network Model: A Field Example from Shale Oil Reservoir in Songliao Basin, China

Energies, 2023
The pore-throat radius of the shale oil reservoir is extremely small, and it is difficult to accurately obtain the absolute permeability and oil–water two-phase relative permeability of the actual oil reservoir through conventional core experiments ...

Influence of Hydration on Shale Reservoirs: A Case Study of Gulong Shale Oil

Minerals
In the process of the exploration and development of shale oil, the influence of hydration on shale reservoirs is complex, as it can not only improve porosity and permeability, but also lead to reservoir instability. At present, there is a lack of systematic understanding of the influence of hydration on the physical and chemical properties of shale ...

Optimizing Graphene Oxide Interlayer Spacing for Zeolitic Imidazolate Framework‐8 Growth Toward Enhanced Shale Oil Separation [PDF]

Advanced Science, Volume 12, Issue 43, November 20, 2025.
Quaternary ammonium salts are used to control the spacing between GO layers, enabling in situ growth of ZIF‐8. The resulting ZIF‐8‐GO membrane exhibits nearly complete rejection of n‐docosane in n‐hexane, solvent permeance of 16.4 ± 0.8 L m−2 h−1 bar−1, and enriches alkanes and aromatics with a molecular weight cut‐off of 310 g mol−1 in shale oil ...

Coupling thermal and maturity histories of the Gulong shale oil reservoir in the Songliao Basin: Insights from vitrinite reflectance and apatite fission track

Unconventional Resources
The coupling relationship between the thermal state and maturation during the geological historical period is critical for shale oil-gas exploration because their present distribution characteristics are not probably the same.
