Excerpt from Oil Prospecting, Drilling and Extraction For the man. Who desires to know how oil is found, the geological formations in which it is found and the methods that are used in its development and extraction this book has been prepared. In the mining industry for the prospector, miner, geologist and engineer many books have been written. However, the prospector for oil, the driller and'the general operator have never had any book giving. Any' classified and systematic data. In this book I have, therefore, attempted to fulfill the requirements of the last mentioned. Especially for Canada is this now needed, where vast areas of oil' formations with tremendous productive potentialities lie unprospected when wells are being drilled in large numbers in other parts of the World where infinitely fewer' indications for large production existed at the initial stage of development. If the petroleum prospector can work from the standpoint of the trained geologist his efforts will be greatly simplified and will. Be much more effective. This book is designed to furnish the information that will permit the. Prospector to work'in' this way. Petroleum geology has been a specialized profession only within the last ten years. Previous to that time all oil men chose locations for wells and did all other work by chance and by guess.
