Excerpt from Petroleum Mining and Oil-Field Development: A Guide to the Exploration of Petroleum Lands, and a Study of the Engineering Problems Connected With the Winning of Petroleum Including Statistical Data of Important Oil-Fields, Notes on the Origin and Distribution of Petroleum, and a Description of The The paucity of practical books on the important subject of Petroleum Mining, which has now assumed such gigantic proportions and proved under careful guidance to be such a lucrative form of investment, is sufficient justification for the preparation of this volume. Whilst a great mass of valuable literature in almost all branches of the petroleum industry has been issued in pamphlet form in many countries and several languages by private individuals and Government officials, the information is not available to the general reader, and there are very few publications where the data are assembled and can be applied in contrasting widely separated oil-fields. The reason is partly due to the world-wide distribution and varied character of oil-fields, which prevents all but a few, who are professionally associated with Petroleum Mining, and who almost exclusively devote their time to that branch of Engineering, from having opportunities of comparing and applying in practice deductions of independent local operators. Petroleum Mining is a branch of Engineering in which, perhaps, more than in any other, specialisation is essential and practical training necessary, as ordinary mining knowledge does not materially assist the engineer. Petroleum, being a fluid, is subject to laws which apply to no solid mineral. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
