... Abstract Simulation of gas huff-n-puff (HnP) in core models is often simplified by assuming homogenous, isotropic models, which are not representative of fine-grained multi-component shales with multiple types of pore space and anisotropic permeability. According to the previous literaturte...

...Multi-Scale Depletion To investigate the phase behavior of the fluid under the confinement effect, we simulate the constant composition expansion (CCE) and constant volume depletion (CVD) using the multi-scale model ( Fig. 2 ). The CCE and CVD are typical PVT tests to investigate bulk fluid...

In the simulation, the CSI cycles of the auxiliary horizontal well were set at 0, 1, 2, and 3, and each cycle included 10 days of steam injection, 2 days of soaking and 2 months of production. It can be seen from Fig. 4 that with the increase...

... simulator that solves poro-thermo-elasticity. We used it to simulate 3- dimensional fracture propagation induced by cold water injection and, at the same time, calculate the stress field influenced by the thermo-poro-elastic effect in heterogeneous reservoir layers. Effective stress in the bounding layer...

It is can therefore be concluded that this kind of time-dependent rate can improve oil recovery at very low additional rate within the capacity of pumps for the field EOR processes. chemical flooding methods constant rate Simulation...

Bubble point, swelling factor, criticality and fluid volumetrics are studied in comparison to the behavior of the bulk fluid. It is found that fluid in nanopores becomes supercritical...

Leach and Yellig (1981 ) successfully simulated a one-dimensional (1D) miscible CO 2 displacement using a fully compositional model. Their numerical results matched the laboratory results well regarding the saturation profile and oil...
