All examples discussed in the book rely on the MATLAB Reservoir Simulation Toolbox (MRST), which is a free, open-source software that can be used for any purpose under the GNU General Public License version 3 (GPLv3). The toolbox is primarily developed by my research group at SINTEF, which is the fourth-largest contract research organization in Europe. The software started out as a research code developed to study consistent discretization and multiscale solvers for incompressible two-phase flow on stratigraphic and unstructured polyhedral grids. Over the past 6–7 years the software has been applied to research a wide spectrum of other problems related to reservoir modeling, and, as a result, the software today has many of the same capabilities that can be found in commercial reservoir simulators. In addition, it contains a spectrum of new research ideas; some of these were discussed in Chapters 13 and 14. At least for the time being, our main motivation for continuing to maintain and develop the software is to have a versatile research platform that enables researchers at SINTEF to rapidly develop proof-of-concept implementations of new ideas and then subsequently, and rather effortlessly, turn these into software prototypes that could be verified and validated for problems of industry-standard complexity with regard to flow physics and geological description of geology. A second purpose is to support the idea of replicable/reproducible research, as well as to enable us to effectively leverage results from one research project in another. Over the years, we have also seen that MRST is an efficient teaching tool and a good platform for disseminating new ideas. Maintaining and developing the software as a reliable community code takes a considerable effort, but by carefully documenting and releasing our research software as free, open source, we hope to contribute to simplifying the experimental programming of other researchers in the field and give a head start to students about to embark on a master’s or PhD project.","PeriodicalId":218326,"journal":{"name":"An Introduction to Reservoir Simulation Using MATLAB/GNU Octave","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130011896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Likewise, Section 7.2 introduced fully implicit discretizations for compressible single-phase flow, and discussed how to use a Newton–Raphson method to linearize and solve the resulting system of discrete equations. With some modifications, these techniques are all we need to describe the most widespread approach to simulate compressible, multiphase flow. For incompressible multiphase flow, on the other hand, it is common to write the system as a pressure equation and one or more transport equations and use specialized discretization schemes for each subequations. Chapter 6 discussed consistent schemes for elliptic pressure equations. This chapter reviews some of the particular challenges that lie in discretizing transport equations. If you are not interested in this wider perspective and only wish to know the simplest possible approach to solving saturation equations, you can jump directly to Section 9.4 on page 286, which discusses the standard upstream mobilityweighting method implemented for general polyhedral grids in the incomp module of MRST.","PeriodicalId":218326,"journal":{"name":"An Introduction to Reservoir Simulation Using MATLAB/GNU Octave","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126588543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Describing all flow processes pertinent to hydrocarbon recovery or CO2 storage with a single model is therefore not possible. Geological characterization therefore usually involves a hierarchy of models that each covers a limited range of physical scales cover a wide range of physical scales. Section 2.3 introduced you to the concept of representative elementary volumes and mentioned various types of models used for flow studies including flow in core samples (cm scale), bed models (meter scale), sector models (tens to hundreds of meters), and field models (km scale). Geocellular models at the field/sector scale are made to represent the heterogeneity of the reservoir and possibly incorporate a measure of inherent uncertainty in reservoir simulation. Pore, core, and bed models are mainly designed to give input to the geological characterization and to derive flow parameters for simulation models. All model types must be calibrated against static and dynamic data of very different spatial (and temporal) resolution: thin sections, core samples, well logs, geological outcrops, seismic surveys, well tests, production data, core flooding and other laboratory experiments, etc. To learn more about the process of building reservoir models, you should consult the excellent textbook by Ringrose and Bentley [265]. To systematically propagate the effects of small-scale geological variations observed in core samples up to the reservoir scale, we need mathematical methods that can homogenize a detailed fine-scale model and replace it with an equivalent model on a coarser scale that contains much fewer parameters that represent the behavior of the fine-scale model in an averaged sense; see Figure 15.1. Such techniques are not only used to incorporate the effect of small-scale models into macroscale models. High-resolution geocellular models used for reservoir characterization on field or sector scale tend to contain more volumetric cells than contemporary simulators can handle without having to resort to massively parallel high-performance computing. As a result, flow simulations are usually performed with models containing less details than those used for characterization. Even if you had all the computational power you needed, there are several arguments why you should still perform your simulations on coarser models. First of all, one can argue that high-resolution models tend to contain more","PeriodicalId":218326,"journal":{"name":"An Introduction to Reservoir Simulation Using MATLAB/GNU Octave","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121662544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
