Nodal Analysis of Oil and Gas Production Systems provides a modern view on the use of nodal analysis techniques to optimize the production from oil and gas wells. It covers multiphase flow through flow lines, wells, chokes and the near-well reservoir. It teaches the development of mathematical models for those system elements, and how to implement these in computer code. It explains the underlying physics, starting from first principles whenever possible, and reverting to empirical correlations whenever necessary. It covers the essential concepts in nodal analysis of a well system and aims at providing the readers with enough knowledge to use commercial nodal analysis software for more complex systems, explore the literature in this field, and expand their knowledge.This book is based on material used in a three-month course for first-year graduate students in the Petroleum Engineering MSc program at Delft University of Technology (TU Delft). This course aims at providing skills in the development and use of mathematical and computer models for flow through the various parts of an oil and gas production system. The underlying idea is that a basic understanding of the numerical implementation of theoretical concepts should be an important element in the education of all engineering students, even though only a few of them will become tool developers and most of them will just use software tools whose inner workings are hidden behind slick user interfaces. Although the book is primarily intended for classroom use, it may also be of value for practicing engineers or researchers who want to get acquainted with the essentials of nodal analysis or learn more about the underlying theory.* Prerequisites are a basic understanding of physical transport phenomena; calculus, including first-order differential equations; and preferably an acquaintance with hydrocarbon properties and oil and gas well completions.Questions and exercises are provided at the end of each chapter. Some of those involve computations that can be performed by hand with a calculator, while others require the use of a computer to run the matlab routines that accompany the book. matlab questions and assignments form an important ingredient of the course, and a basic level in computer programming will therefore be of help to benefit maximally from the book. Handcalculations are primarily seen as a means to obtain quick order-of-magnitude estimates or to verify the results of computer simulation
