About the Author
Changhong Gao received his degrees in petroleum
engineering from China University of Petroleum, University of
Tulsa, and Curtin University. He worked for Sinopec as a field
engineer and research engineer. He also taught various petroleum
engineering courses at United Arab Emirates University,
University of Aberdeen, and Petroleum Institute of Abu Dhabi.
His teaching and research interests include production system
design, enhanced oil recovery, and drilling mud. He has
published more than 30 journal papers and presented a few papers at SPE and APPEA
conferences. In 2013, he was elected Taishan Scholar by Shandong province
government, as well as Yellow River Delta Scholar by Dongying city government.

Preface
After some years of experiences in both university and industry, the author
realizes there is a demand for a book that covers the complete petroleum production
chain.
This book covers the most important aspects of petroleum production technology.
Chapter 1 and chapter 2 present properties of oil, gas, and reservoir rock. Chapter 3
introduces mechanisms of primary recovery, secondary recovery, and enhanced oil
recovery. Chapter 4 presents equations that govern fluid flow in reservoir. Chapter 5
introduces onshore and offshore facilities for drilling and production. Chapter 6
presents options for lower and upper completions. Chapter 7 introduces well
productivity index and inflow performance relationship. Chapter 8 presents
single-phase flow and multiphase flow in wells, as well as nodal analysis technique for
production optimization. Chapter 9 introduces artificial lift methods, including sucker
rod pump, gas lift, and electrical submersible pump etc. Chapter 10 presents techniques
for well stimulation, namely acidizing and fracturing. Chapter 11 and chapter 12
introduce common production problems and remediation techniques, such as sand,
scale, wax, hydrate and asphaltene. Chapter 13 presents separation and treatment for oil,
gas, and water.
After reading this book, the readers gain valuable knowledge in modern
production technology in the most concise and straightforward manner, without
struggling through tedious and excessive descriptions. A few illustrative examples are
included to make theories easy to understand. This book serves as a textbook for
students studying petroleum engineering, as well as a reference book for engineers in
petroleum industry.
The Author is grateful for the financial support from Shandong province
government through the prestigious Taishan Scholar program. Dongying city
government also provided financial support through Yellow River Delta Scholar
program.
