Title: A numerical sensitivity analysis of streamline simulation
Author: Chaban Habib, Fady Ruben
Abstract: Nowadays , field development strategy has become increasingly dependent on the results of reservoir simulation models . Reservoir studies demand fast and efficient results to make investment decisions that require a reasonable trade off between accuracy and simulation time . One of the suitable options to fulfill this requirement is streamline reservoir simulation technology , which has become very popular in the last few years . Streamline (SL ) simulation provides an attractive alternative to conventional reservoir simulation because SL offers high computational efficiency and minimizes numerical diffusion and grid orientation effects . However , streamline methods have weaknesses incorporating complex physical processes and can also suffer numerical accuracy problems . The main objective of this research is to evaluate the numerical accuracy of the latest SL technology , and examine the influence of different factors that may impact the solution of SL simulation models . An extensive number of numerical experiments based on sensitivity analysis were performed to determine the effects of various influential elements on the stability and results of the solution . Those experiments were applied to various models to identify the impact of factors such as mobility ratios , mapping of saturation methods , number of streamlines , time step sizes , and gravity effects . This study provides a detailed investigation of some fundamental issues that are currently unresolved in streamline simulation .
