... production data. We shed some light on two issues that impact the recovery significantly. One issue is the grid refinement; we create three models with varying grid size. We study the effect of gas molecular diffusion and report the added recovery using different diffusion coefficients. The third issue...

... a large contact area for injected gas to penetrate into the ultra-low permeability matrix. The effect of molecular diffusion was also investigated, but this did not appear to have a major impact on recovery for the modeled conditions at the field scale. The cycling scheme evaluation indicates that oil...

... size distribution in shale formations is stretched down to nano-meters, the system response violates the predictions of Darcy's law. Depending on pore size and gas properties, non-Darcy flow mechanisms such as slip-flow, molecular diffusion, and Knudsen diffusion can affect the matrix deliverability...

...) investigated the diffusion effect on recovery performance in a fractured gas/condensate reservoir. Their simulation results showed that molecular diffusion has a significant effect on gas recovery if the reservoir pressure is below the minimum miscible pressure. Modeling of the diffusion effect on ultimate oil...
