Digital rock physics (DRP), via both direct numerical simulation and pore-network modeling,
holds great promise in terms of probing such pore-scale controls on transport, particularly …

Recent reports have demonstrated that gas injection can improve oil recovery of tight
reservoirs after natural depletion, with major projects in progress worldwide. There is …

Understanding and controlling confined CO 2 fluids in nanopores is at the heart of the CO 2
enhanced oil recovery in shale reservoirs. Here, for the first time, qualitative and quantitative …

Shale oil, as one of the unconventional resources, has become increasingly important to
supplement conventional oil and gas. Although CO2 has great potential to enhance shale oil …

In unconventional petroleum reservoirs, such as shale gas, shale oil, tight oil, and tight gas
reservoirs, the microscopic pore structure, namely, the size, geometry, distribution, and …

A series of core-flood tests were performed, together with nuclear magnetic resonance
measurements of the initial and residual oil saturation states in the cores, to investigate the …

Fracture, as an important factor affecting the quality of reservoirs, has always been one of
the most crucial research contents in the process of oil and gas field development. The basis …

CO2 injection, either miscible or immiscible, has been recognized as a promising method to
enhance oil production for tight reservoirs, with major projects in progress worldwide. This …
