# Computational Methods for Multiphase Flows in Porous Media by Zhangxin Chen

By Zhangxin Chen

This ebook deals a primary and useful advent to using computational tools, really finite point equipment, within the simulation of fluid flows in porous media. it's the first e-book to hide a wide selection of flows, together with single-phase, two-phase, black oil, risky, compositional, nonisothermal, and chemical compositional flows in either usual porous and fractured porous media. furthermore, more than a few computational equipment are used, and benchmark difficulties of 9 comparative answer tasks prepared by means of the Society of Petroleum Engineers are awarded for the 1st time in booklet shape. Computational tools for Multiphase Flows in Porous Media reports multiphase move equations and computational how to introduce simple terminologies and notation. an intensive dialogue of functional points of the topic is gifted in a constant demeanour, and the extent of remedy is rigorous with no being unnecessarily summary. each one bankruptcy ends with bibliographic info and routines. This publication can be utilized as a textbook for graduate or complex undergraduate scholars in geology, petroleum engineering, and utilized arithmetic, and as a reference ebook for execs in those fields, in addition to scientists operating within the region of petroleum reservoir simulation. it will possibly even be used as a instruction manual for workers within the oil who desire a simple knowing of modeling and computational technique options and through researchers in hydrology, environmental remediation, and a few parts of organic tissue modeling. Calculus, physics, and a few acquaintance with partial differential equations and easy matrix algebra are important necessities. checklist of Figures; record of Tables; Preface; bankruptcy 1: advent; bankruptcy 2: movement and delivery Equations; bankruptcy three: Rock and Fluid houses; bankruptcy four: Numerical equipment; bankruptcy five: resolution of Linear structures; bankruptcy 6: unmarried part movement; bankruptcy 7: Two-Phase circulation; bankruptcy eight: The Black Oil version; bankruptcy nine: The Compositional version; bankruptcy 10: Nonisothermal movement; bankruptcy eleven: Chemical Flooding; bankruptcy 12: Flows in Fractured Porous Media; bankruptcy thirteen: Welling Modeling; bankruptcy 14: unique subject matters; bankruptcy 15: Nomenclature; bankruptcy sixteen: devices; Bibliography; Index.

For the fluctuations round the capability yet really fluctuations, and showing within the following incompressible approach of equations: on any wall; at preliminary time, and are assumed identified. This contribution arose from dialogue with J. P.

Example text

The simplest elliptic equation is the Poisson equation A typical parabolic equation is the heat conduction equation Finally, the prototype hyperbolic equation is the wave equation In the one-dimensional case, this equation can be "factorized" into two first-order parts: The second part gives the first-order hyperbolic equation We now turn to the two-phase flow equations. While the phase mobilities ka can be zero (cf. Chapter 3), the total mobility A. 46) is elliptic. If one of the densities varies, this equation becomes parabolic.

5) by where q(l) indicates the volume of the fluid produced per unit time at x (l) and 8 is the Dirac delta function. For point sources, q is given by where q(l) and p (/) denote the volume of the fluid injected per unit time and its density (which is known) at x (l) , respectively. The treatment of sources and sinks will be discussed in more detail in later chapters (cf. Chapter 13). 2. 3 15 Equations for slightly compressible flow and rock It is sometimes possible to assume that the fluid compressibility Cf is constant over a certain range of pressures.

The symbol SCM (standard cubic meter) is not a standard SI unit; it indicates the amount of mass contained in one cubic meter calculated at standard pressure and temperature. The use of unit prefixes is sometimes convenient (cf. 4), but it does require care. If a prefixed unit is exponentiated, the exponent applies to the prefix as well as the unit.
