1. Gessel, Gregory M. A New Method for Treating Wells in Reservoir Simulation.

Degree: MS, 2007, Brigham Young University

A new method for formulating finite difference equations for reservoir simulation has been developed. It can be applied throughout the entire simulated reservoir or to local segments. When applied to cells containing vertical, fully penetrating, straight-line wells in a homogeneous reservoir, the resulting equations are equivalent to Peaceman's classical well equations used in most reservoir simulators today. However, when the new finite difference equations are applied to both the well-containing cells, and their neighbors, the accuracy of the simulation improves substantially. The method produces still better accuracy results when applied throughout the reservoir. Unlike the Peaceman correction, the new method also applies to reservoirs containing wells of complex geometry. This includes wells that are closely spaced and wells near reservoir faults and external boundaries. The method results from the incorporation of approximate analytical expressions for the pressure into the reservoir simulator's finite difference equations. By incorporating the “physics” of the flow into the solution, rather than relying on polynomial-based finite difference equations based on Taylor's series, as is usually done, solution accuracy improves. Accuracy is particularly improved around the wells where near-singularities in the pressure occur. Polynomials are incapable of accurately representing singularities.

2. Chang, Dahwei. Peaceman's numerical productivity index for non-linear flows in porous media.

Degree: Mathematics, 2009, Texas Tech University

From Darcy’s law to Darcy-Forchheimer equation, there have being a lot efforts finding solutions for flows in porous media. Peaceman used a system of well blocks to replace the well bore in finding numerical solutions for linear flows. Our work uses a single well block to find the pressure distribution throughout the well for non-linear flows. In the process we found a block invariant which can be used to build the pressure distribution formula. From it, we can find the productivity index, one of the important factors in petroleum engineering. Theoretical derivation and numerical data are also presented in this report. Advisors/Committee Members: Aulisa, Eugenio (Committee Chair), Toda, Magdalena D. (committee member), Howle, Victoria E. (committee member).
