Petroleum and Natural Gas In Oklahoma By L. C. JJNIDER, A. M., Assistant Director of the Oklahoma Geological Survey Oklahoma City, Okla. THE HARLOW-RATLIFF COMPANY 1913 PREFACE This hand book is written with the view of putting within reach of all interested, a comprehensive but brief review of the oil and gas industry of Oklahoma, and the prospects for the future development of this industry. A large portion of the book is taken up with descriptions of the producing fields and discussions of the conditions in these fields. The geology of the State is considered with reference to the occurrence of oil and gas in the developed areas and with reference to the probable or possible occur rence of these substances in other portions of the State. The methods of prospecting for oil and gas and the use of geology as a guide for prospecting are considered rather fully. Some items of general interest, such as brief notes on transportation and refining, are included. In the con sideration of the oil and gas of the different fields it is necessary to refer constantly to the geologic conditions which exist in the area. For the benefit of those who have had no training in geology brief discussions of the nature and mode of origin of rocks, and of the structure or posi tion in which the rocks are found are given. All the geol ogic terms used in the book are explained in these sections. Development maps showing the state of development in the early part of 1913, are given for all the important pools. The information for these maps has been obtained from the maps of the Gulf Pipe Line Company and of the Tulsa Mapping Company. The character of the rocks passed through in drilling in the different poolsis illus trated by means of typical well logs. The statistics are taken from Mineral Resources of the United States pub lished by the United States Geological Survey. 1NTRODUCT10JN The daily output of oil in Oklahoma has a value of more than 1,000,000 a week. Natural gas to the value of more than 185,000 is marketed every seven days. The total value of oil and gas is now running at about 7Q, Q QQ, -000 a year. These figures more than any words will im press on the mind the commercial value of Oklahomas oil and gas industry. To this amount should be added the values of refinery products and natural gas gasoline m well as that of the scores of industries which draw on our natu ral gas for fuel The value of our raw products and of the Industries which subsist directly upon them swell the value of these commodities to an enormous total and make the oil and gas industry one of the first in the State, The present demand for information on oil and gas in Oklahoma is enormous. Few, if any, men are better qualified to supply this information than the author. Mr. Snider has written this book and compiled statistics dur ing such times as he was free from official duties. His in formation has been drawn in large measure from publica tions of the Oklahoma and United States Geological Sur veys. This has been materially supplemented by the per sonal knowledge of the author, acquired during five years of service for the State. During his field and office work Mr, Snider has had excellent opportunity to become con versant with the oil and gas geology of Oklahoma as a whole, and also with geologic and operating conditions in each particular field. In the preparation of this work the author has had in mindto supply general information to those actively en gaged in drilling and developing proven territory to guide in a general way those who are courageously wildcatting n in the various parts of the State and to Inform the gen eral public and especially the prospective investor as to conditions as they now exist. The book is a valuable aid to landowners who may or may not believe that oil and gas underlie their possessions. I have read a large part of Mr...
