Reservoir Characterisation: A comprehensive description of reservoir modelling, starting with the analysis of geological, geophysical and production data. The construction of 3D geological models with particular emphasis on practical and effective modelling. Spatial analysis and geostatistics and their role in the population of 3D grids with geologically believable properties. Issues of measurement scale and the difficulties they cause, both in the incorporation of well log and core data into the model and the rescaling of the geological model for use in numerical simulation.

Numerical Reservoir Simulation: Introduction and overview: Reservoir simulation and management. Derivation of general reservoir flow equations. Reduction to the black oil model. Discrete flow equations for single-phase flow: finite difference approximation. Discretization of the black oil equations. Truncation errors and stability. Tranmissibilities, upstream weighing, implicit and explicit treatment of transmissibilities. Numerical dispersion and grid-orientation effects. Model and grid selection. Model initialization. Treatment of wells in simulators. Pseudo-functions. History matching. Planning and executing a reservoir simulation study.
