## Use of Corner Point Geometry in Reservoir Simulation ...

Use of Corner Point Geometry in Reservoir Simulation. The corner point geometry (distorted grids) is often used as an alternative for complex full-field studies. This approach can better adapt the grid to reservoir boundaries, faults, horizontal wells and flow patterns and is easily used in standard finite difference reservoir simulators.

## Corner Point Grid Geometry in Reservoir Simulation

Corner Point Grid Geometry in Reservoir Simulation. Transmissibility values are calculated in terms of three-vector mutual interface areas, which automatically incorporate corrections for dip and inclined flow. The application of calculated transmissibilities to a simple five point model can lead to an inconsistent finite difference scheme, and to significant errors if the grid is highly distorted.

## Simulation Throughout the Life of a Reservoir

However, the most significant gain has not been in absolute speed, but speed at a mod- erate price. Computational efficiency has reached a stage that allows powerful simula- tors to be run frequently. Numerical simulation has become a reser- voir management tool for all stages in the life of the reservoir.
