Summary and Info
This text forms part of material taught during a course in advanced reservoir simulation at Delft University of Technology over the past 10 years. The contents have also been presented at various short courses for industrial and academic researchers interested in background knowledge needed to perform research in the area of closedloop reservoir management, also known as smart fields, related to e.g. modelbased production optimization, data assimilation (or history matching), model reduction, or upscaling techniques. Each of these topics has connections to systemtheoretical concepts.The introductory part of the course, i.e. the systems description of flow through porous media, forms the topic of this brief monograph. The main objective is to present the classic reservoir simulation equations in a notation that facilitates the use of concepts from the systemsandcontrol literature. Although the theory is limited to the relatively simple situation of horizontal twophase (oilwater) flow, it covers several typical aspects of porousmedia flow.The first chapter gives a brief review of the basic equations to represent singlephase and twophase flow. It discusses the governing partialdifferential equations, their physical interpretation, spatial discretization with finite differences, and the treatment of wells. It contains wellknown theory and is primarily meant to form a basis for the next chapter where the equations will be reformulated in terms of systemsandcontrol notation.The second chapter develops representations in statespace notation of the porousmedia flow equations. The systematic use of matrix partitioning to describe the different types of inputs leads to a description in terms of nonlinear ordinarydifferential and algebraic equations with (statedependent) system, input, output and directthroughput matrices. Other topics include generalized statespace representations, linearization, elimination of prescribed pressures, the tracing of stream lines, lift tables, computational aspects, and the derivation of an energy balance for porousmedia flow.The third chapter first treats the analytical solution of linear systems of ordinary differential equations for singlephase flow. Next it moves on to the numerical solution of the twophase flow equations, covering various aspects like implicit, explicit or mixed (IMPES) time discretizations and associated stability issues, NewtonRaphson iteration, streamline simulation, automatic timestepping, and other computational aspects. The chapter concludes with simple numerical examples to illustrate these and other aspects such as mobility effects, wellconstraint switching, timestepping statistics, and systemenergy accounting.The contents of this brief should be of value to students and researchers interested in the application of systemsandcontrol concepts to oil and gas reservoir simulation and other applications of subsurface flow simulation such as CO2 storage, geothermal energy, or groundwater remediation.
