Super Element Method of Oil Reservoir Simulation
نویسندگان
چکیده
The paper describes the theoretical framework and results of using an rapid three-dimensional super element model of oil field development. The model makes it possible to speed up calculation of two-phase filtration in an oil reservoir by hundreds of times owing to the use of large computational cells – super elements, the number of which corresponds to the number of wells in the field. Accuracy of the numerical solution is ensured by a formulation of the problem in terms of the smooth mean fields of pressure and saturation with a selective refinement of the solution in the near of the wells on independent detailed nested grids.

Reservoir Simulation with the Finite Element Method Using Biot Poroelastic Approach
We are developing a finite element program for oil and gas reservoir simulation based on Biot’s poroelastic theory, where a simultaneous solution is sought for both the pore pressure and strain in the solid phase. Several 2-D and 3-D cases are presented, which are compared with analytical solutions for verification of this approach. We have also applied this method to simulate surface subsidenc...

متن کاملA Fully Integrated Method for Dynamic Rock Type Characterization Development in One of Iranian Off-Shore Oil Reservoir
Rock selection in modeling and simulation studies is usually based on two techniques; routinely defined rock types and those defined by special core analysis (SCAL). The challenge in utilizing these two techniques is that they are frequently assumed to be the same, but in practice, static rock-types (routinely defined) are not always representative of dynamic rock-types (SCAL defined) in the re...
