There is only one substance known to mankind that can cause wars, influence global economies, and make countries rich: petroleum. But how much does the average person, even the average engineer, know about it? This book describes the petroleum industry in easy-to-understand language for both the layperson and engineer alike. From the economics of searching for oil and gas, getting it out of the ground, into pipelines, into refineries, and, finally, into your gas tank, this book covers the petroleum industry like no other treatment before.
