an introduction to Reservoir Simulation using matlab gnu octave user guide for the matlab Reservoir Simulation toolbox mrst
2019Co-Authors: Knut-andreas LieAbstract:This book provides a self-contained introduction to the Simulation of flow and transport in porous media, written by a developer of numerical methods. The reader will learn how to implement Reservoir Simulation models and computational algorithms in a robust and efficient manner. The book contains a large number of numerical examples, all fully equipped with online code and data, allowing the reader to reproduce results, and use them as a starting point for their own work. All of the examples in the book are based on the MATLAB Reservoir Simulation Toolbox (MRST), an open-source toolbox popular popularity in both academic institutions and the petroleum industry. The book can also be seen as a user guide to the MRST software. It will prove invaluable for researchers, professionals and advanced students using Reservoir Simulation methods.

mixed multiscale finite elements and streamline methods for Reservoir Simulation of large geomodels
Advances in Water Resources, 2005Co-Authors: Jørg E. Aarnes, Vegard Kippe, Knut-andreas LieAbstract:We present a new approach to Reservoir Simulation that gives accurate resolution of both large-scale and fine-scale flow patterns. The method uses a mixed multiscale finite-element method (MMsFEM) to solve the pressure equation on a coarse grid and a streamline-based technique to solve the fluid transport on a fine-scale subgrid. The MMsFEM is based on the construction of special approximation velocity spaces that are adaptive to the local properties of the differential operator. As such, MMsFEM produces a detailed subgrid velocity field that reflects the impact of the fine-scale heterogeneous structures. By combining MMsFEM with rapid streamline Simulation of the fluid transport, we aim towards a numerical scheme that facilitates routine Reservoir Simulation of large heterogeneous geomodels without upscaling. The new method is applied to two different test cases. The first test case consists of two (strongly) heterogeneous quarter five-spot problems in 2D. The second test case is a 3D upscaling benchmark taken from the 10th SPE Comparative Solution Project, a project whose purpose is to compare and validate upscaling techniques. The test cases demonstrate that the combination of multiscale methods and streamlines is a robust and viable alternative to traditional upscaling-based Reservoir Simulation.

A fast marching method for Reservoir Simulation
Computational Geosciences, 2000Co-Authors: K. Hvistendahl Karlsen, Knut-andreas Lie, Nils Henrik RisebroAbstract:We present a fast marching level set method for Reservoir Simulation based on a fractional flow formulation of two-phase, incompressible, immiscible flow in two or three space dimensions. The method uses a fast marching approach and is therefore considerably faster than conventional finite difference methods. The fast marching approach compares favorably with a front tracking method as regards both efficiency and accuracy. In addition, it maintains the advantage of being able to handle changing topologies of the front structure.

state of the art of geothermal Reservoir Simulation
Geothermics, 2001Co-Authors: Michael Osullivan, Karsten Pruess, Marcelo J LippmannAbstract:Computer modeling of geothermal systems has become a mature technology with application to more than 100 fields world-wide. Large complex three-dimensional models having computational meshes with more than 4000 blocks are now used routinely. Researchers continue to carry out fundamental research on modeling techniques and physical processes in geothermal systems. The new advances are adopted quickly by the geothermal industry and have also found application in related areas such as nuclear waste storage, environmental remediation and studies of the vadose (unsaturated) zone. The current state-of-practice, recent advances and emerging trends in geothermal Reservoir Simulation are reviewed.

Reservoir Simulation; State of the art
Journal of Petroleum Technology, 1991Co-Authors: E.a. BreitenbachAbstract:This paper describes the state of the art in oil and natural gas Reservoir Simulation for the nonexpert, focusing primarily on advances that have occurred since a similar paper was published by Coats in 1982. For completeness, a history of Simulation is given first, followed by a brief and simple review of the Simulation process. Advances in Simulation technology are then described, highlighting those in Reservoir description and Simulation of naturally fractured Reservoirs, hydraulic fracturing, and horizontal wells. The future of Reservoir Simulation is discussed last.
