Development Of A Two-Dimensional Single-phase Fluid Reservoir Simulator

Modeling of the flow of fluids through porous media serves as the backbone of reservoir engineering studies.A detailed evaluation of pressure and flow rate of reservoir fluids as a function of space and time are essential in order to visualize the dynamics of fluid flow through porous media.Single-phase models are the simplest way to characterize the flow of fluid through porous media.Despite their simplicity,these kinds of models give an equation for the pressure distribution in the reservoir and are used for many early stage as well as simplified flow studies.This thesis presents the development and application of an in-house two-dimensional single-phase fluid reservoir simulator.The finite-difference method(FDM)was used for approximating the solution of the governing partial differential equations.We used Strongly Implicit Procedure(SIP)to solve for the governing partial differential equations.The in-house simulator developed in this work has been applied to two cases: a slightly compressible fluid reservoir and a compressible fluid reservoir.Matlab was used as a programming language to create our 2-D single-phase fluid simulator.In order to ensure the correctness of the results of our in-house reservoir simulator,an incremental material as well as a cumulative material balance check has been performed.All of them gave us a value,which is close to unity for both slightly compressible fluid and compressible fluid reservoir.This proved the correctness of the results,which we obtain from our simulation runs.
