In cases with significant density difference between the injection mixture and the reservoir fluids, segregation can take place on short temporal scales relative to the typical time-step lengths of the simulation. A fully resolved 3D description is computationally demanding and is often difficult to...

New Sequential Fully Implicit (SFI) methods for compositional flow simulation have been recently investigated. These SFI schemes decouple the fully coupled problem into separate pressure and transport problems and have convergence properties comparable to the Fully Implicit (FI) method. The pressure...

Compositional simulation is necessary for a wide variety of reservoir simulation applications, and it is especially valuable for accurate modeling of near-miscible gas injection for enhanced oil recovery. Since the nonlinear behavior of gas injection is sensitive to the resolution of the simulation ...

CO2 capture and storage is an important technology for mitigating climate change. Design of efficient strategies for safe, long-term storage requires the capability to efficiently simulate processes taking place on very different temporal and spatial scales. The physical laws describing CO2 storage ...

Implicit transport solvers used in reservoir simulation can take longer time steps than explicit solvers, but for long time steps, the commonly used Newton-Raphson’s method will often fail to converge. The convergence issues may manifest themselves as oscillating residuals even though the implicit d...

Compositional simulation is attractive for a wide variety of applications in reservoir simulation and it is especially valuable when modeling gas injection for enhanced oil recovery. Since the nonlinear behavior of gas injection is sensitive to the resolution of the simulation grid used, it is impor...
