Are you concerned about the current oil and gasoline prices? Do you want to understand what will happen in the future with energy and our standard of living? Then you must read this book. And you will learn that in 1956 a geologist working for Shell Oil, M. King Hubbert, made a prediction (in a paper titled "Nuclear Energy and the Fossil Fuels"). Hubbert then predicted that all U.S. oil production would peak in the early 1970s. At the beginning, all the experts and gurus discarded this men's prediction. But he was right, because U.S. oil production peaked out in 1970. Afterwards, mainly in the 1990s, geologists, oil engineers and analysts began referring to Hubbert's Peak, and using his methods to estimate the peak year for word oil. That is to say, at what point humanity will have consumed half of all world oil endowment, which took hundred of million of years to accumulate. A point that only takes 100 years to reach since oil production started ..... If the actual predictions are correct ( Hubbert's curve is not longer debatable; pending issue is the correct peak year, now estimated to be between 2007 and 2012) the implications for world economy, oil prices, the premises of occidental civilization, will be devastating. So, even if you are not into oil, gas or energy, I consider this book to be of mandatory reading to better understand the workings of the energy world, and dismiss certain current myths, like the possibility of expanding oil production radically through new methods; drilling deeper or in new places. The author of this book, Professor Kenneth Deffeyes, Professor Emeritus at Princeton University, is highly qualified to take you on a fascinating ride, which will qualify non experts to better understand all the factors involved in oil production and future possibilities. Reader will comprehend the origins of oil; what are reservoirs and oil traps; how does one find oil; what are the products that derive from oil, and how do they impact our current lives; how do you drill for oil and extract it; where and when can you discover an oil field. Better yet, this book will leave you in a position to better assess the future of fossil fuels, and certain realities about much discussed, but seldom understood, alternative energy sources. Congrats to Professor Deffeyes, for preaching a clear and understandable energy Gospel. He has proven his worth, as an ex fellow worker of Magister Hubbert, when he started his personal journey, back in the 1950s, at Shell's research lab in Houston....A review by Luciano Lupini.
