When it was first published in 1939, oil historian James A. Clark called this book, the most valuable collection of historical, biographical, and statistical data on Texas oil ever assembled. That is still true today. It is the definitive history of the petroleum industry in Texas, exhaustively addressing the geology, technology and economic impact of the industry that made Texas synonymous with oil. Mr. Warner provides a well-articulated and accurate account of the early discoveries, fields, and oilmen in the state. This expanded edition includes previously unpublished material extending further the scope of the original 1939 text. Illustrated with photos and production statistic charts by county.
