Bulletin 19 Physical And Chemical Properties Of The Petroleumb Of The San Joaquin Valley, Cal

Realizing the great importance and wide application of petroleum and its products for fuel,lighting and lubrication, and the absence of authentic and comprehensive information in the literature on the commercial value of American petroleums, the United States Geological Survey has for a number of years' been making analyses and other examinations of these oils and their products. In 1907 the technologic branch of the Survey began a study of certain economic problems having to do with the natural mineral oils. The prime object of the investigations was to determine the economic value of the petroleums and natural gases in the United States with special reference to the supplies in the public lands, and to ascertain how these resources could be utilized in the industries withleast waste and greatest efficiency. This work, which is now being conducted by the petroleum section of the Bureau of Mines under authority of the act of May 16, 1910, will include the collection at the wells and refineries of information as to the following details: Facilities for handling and storage at the wells. Facilities for transportation, whether by pipe line, rail, or water. Distance to the nearest port or center of industry and time necessary for delivery. Facilities for storage at such point of delivery. Suitability of the crude oil for fuel, or the treatment necessary to convert itmost economically into the best fuel. Best processes of refining or of converting the crude oil into its many products. The examination of these products. The utilization of the by-products and residues of the refineries. The collection of adequate and reliable samples, and the complete chemical and physical examination ofthese samples in the laboratory.
