I was just wondering if anyone else had heard of this book. The author was a reservoir engineer, and describes the fight between engineers and geologists for control of the right to estimate proven reserves. He thinks oil reserves are overestimated by 50%, so for every three barrels of oil estimated, only two will actually flow, The only exception is Russia, where the overestimate is 200%, i.e. for every three barrels estimated, only one barrel will flow. In other words, divide by three. He also thinks that the shale revolution can be better described as the siltstone revolution. The crux of his argument is that geologists include oil reserves from low quality rock that will never flow.

Comments? I find it interesting and decided to throw it out for discussion.
