Fast estimation of pressure propagation on general grids

Abstract

To optimize reservoir recovery, estimating drainage volume for different well scenarios to find optimal well locations, is crucial. Knowing the pressure propagation for different well scenarios we can use this to estimate drainage volume for the different scenarios.

In this thesis we have shown that pressure propagation in a reservoir can be modeled by an Eikonal equation. We have introduced a numerical solution of the Eikonal equation that estimates the pressure propagation in heterogeneous reservoirs represented by general grids. The method was tested by comparing the results to results from different solution methods.
