Petroleum Accumulation Zones on Continental Margins

Much of the world’s petroleum is located on continental margins, and any further development of these offshore deposits would be impossible without new technologies and new methods contained in this volume. Written by some of the world’s foremost authorities on oil and gas, this volume explains for the practicing engineer and the engineering student some of the most important and cutting-edge techniques for developing offshore fields on continental margins.

Yu. N. Grigorenko, PhD, after graduating in 1959 from the Leningrad Mining Institute, became a well-known specialist in the oil and gas industry and is currently the Chairman of the Dissertation Council of the All-Russia Petroleum Research Exploration Institute (VNIGRI). He has written over 200 publications, including six monographs, and has received many honors, including the Honored Geologist of the Russian Federation.

George V. Chilingar, PhD, is an Emeritus Professor of Engineering at the University of Southern California. He is one of the most well-known petroleum geologists in the world and the founder of several prestigious journals in the oil and gas industry. He has published over 70 books and 500 articles and has received over 100 awards over his career.

V. S. Sobolev, PhD, is a well-known petroleum geologist and is a professor at the Institute of Geology and Minerology at the Russian Academy of Sciences.

T. A. Andiyeva, PhD, and L. I. Zhukova, PhD, are both professors at the All-Russia Petroleum Research Exploration Institute (VNIGRI), Ministry of Natural Resources, Russian Academy of Sciences (RAS), in St. Petersburg, Russia.

Some of the best-known petroleum engineers in the world have come together to produce one of the first comprehensive publications on detailed forecasts of offshore petroleum potential.

As in the Gulf of Mexico, there is a tremendous amount of undeveloped hydrocarbon resources located in the Russian continental shelf, which is under intense scrutiny by the oil and gas industry. Not just American companies, but Chinese, Russian, and European countries are all eyeing this area with a view toward developing these tremendous untapped reserves. These areas remain untapped, primarily because they are essentially unreachable through conventional methods of recovery.

The primary aim of this book is to introduce new, unconventional methods for exploration and development of areas like the Russian continental shelf, showing, through practical applications, how these areas can, in fact, be developed. Not limiting themselves to the Russian continental shelf, the authors use these particular areas as a proving ground for their methods, which could be used in any similar situation in the world.

With reserves in the Middle East and North Sea being decimated at a much faster rate than was originally forecast, drilling in the Gulf of Mexico and in other continental margins to develop new reserves of oil and gas is one of the biggest issues facing the energy industry, indeed our whole world, today. This will be the new challenge for both veteran engineers and students, alike, as they go forward in this new era of world energy production.

This groundbreaking new volume includes:

• Mathematical models never used before for the extraction of oil and gas from continental accumulation zones
• Real-world examples for the petroleum engineering student, focusing on new, unconventional methods, as opposed to traditional methods for offshore operations
• Detailed descriptions of areas such as the Gulf of Mexico, the Arctic, China, and the Russian continental shelf, with a view toward maximizing possible oil and gas reserves in these important accumulation zones
