Introduction: Description of a simulation model; Simplifications and issues that arise in going from the description of a real reservoir to a reservoir simulation model;
Description or reason and circumstances simple or complex reservoir models are required to model reservoir processes; Input data is required; Typical outputs of
reservoir simulations and their use in reservoir development.
Basic concepts in reservoir engineering: Material balance equation for an undersaturated oil reservoir; Conditions under which the material balance equations are
valid; Single and two-phase Darcy Law in one dimension (1D); Gradient and divergence operators as they apply to the generalised (2D and 3D) Darcy Law;
Permeability as a tensor quantity; 2D and 3D Darcy Law with permeability as a full tensor
Reservoir simulation model set-up: Simulation Input – issues to be addressed by simulation,input data required, format of data; Simulation Output - output of
calculations, quality check output data to check for errors in input, post-processing analysis; Analysis of Results - identify impact of reservoir engineering principles in
calculation performed, Identify numerical effects and impact of grid block size and orientation on results, erform simple upscaling calculation to address numerical
diffusion.
Gridding and well modelling: Concept of gridding and of spatial and temporal discretisation; types of grid in 1D, 2D and 3D used in reservoir simulation; numerical
dispersion and grid orientation and the solution to these numerical problems; local grid refinement (LGR), distorted, PEBI and corner point grids; grid

fineness/coarseness; streamline simulation; well models and productivity index (PI); average grid block pressure and Peaceman formula; concept of multi-phase flow
to calculate PIw and PIo.
Flow equations: Physics of single phase compressible flow through porous media; equation for single phase compressible flow (PDE); linearization of PDE for slightly
compressible flow involving the hydraulic diffusivity; extension of the single phase pressure equation to 2D; conservation + Darcy’s law in the two phase case to
arrive at the two phase flow equations for compressible fluids and rock.
Numerical methods in reservoir simulation: Simple finite difference expressions for derivatives, (∂P/∂x), (∂P/∂t) and (∂2P/∂x2); forward difference, the backward
difference and the central difference and the order of the error associated with each; apply finite difference approximations to a simple partial differential equation
(PDE); explicit and an implicit numerical scheme; implicit finite difference scheme applied to a simple linear PDE leading to a set of linear equations which are
tridiagonal in 1D and pentadiagonal in 2D; structure of the pentadiagonal A-matrix in 2D for a given numbering scheme going from (i, j) notation to m-notation where
m is an ordered numbering; solution strategy for the non-linear single phase 2D pressure equation where the fluid and rock compressibility are pressure dependent;
discretised form of both the pressure and saturation equation for two-phase flow; IMPES solution strategy for the discretised two-phase flow equations.
Permeability upscaling: Reason for upscaling; calculation ofeffective permeability in simple models by averaging; numerical upscaling of single-phase flow; effects of
heterogeneity on two-phase flow; limitations of applying single-phase upscaling to a two-phase problem; steady-state, capillary-equilibrium upscaling for two-phase
flow; 2-phase dynamic upscaling (the Kyte and Berry Method); upscaling around a well; upscaling from the core-scale to the scale of a geological model, taking
account of fine-scale structure and capillary effects.
