Advantage has been taken recently of the memory management scheme of a state-of-the-art compositional reservoir simulator to instal the complete program package on an IBM-compatible PC.
Although obviously limited from a time and space consideration in its scope for full scale field simulations, the main simulator can handle grids containing 500 blocks with 10 components on a PC with 640k RAM and associated hard disc capabilities.
Two possible applications for the use of such a package on micro-computers are discussed :
The generation of PVT data for compositional simulation
The simulator has several different options for calculating fluid properties ranging from simple black oil representation, through special 3-component correlations, right up to a choice of Equation of State (EOS).
Sensitivity studies as part of the decision process in defining a grid with a view to eliminating numerical dispersion and grid orientation effects
Particularly applicable to the simulation of miscible displacement processes in a five-spot pattern, Koval1 dispersion theory has been successfully applied to radial diverging and converging flow. Using a biradial mesh with various grid block sizes, results are compared to show the effectiveness of this approach.
