Wells drilled for oil and gas in the United States, 1923, by States and counties or districts-Continued Wells drilled for oil and gas in the United States, 1923, by States and counties or districts-Continued California dry gas wells and dry holes not reported. 1922: Tennessee; 1923: Colorado, New Mexico, Tennessee, and Utah. ACREAGE In the accompanying table the estimate of developed petroleum acreage in the United States in 1923 for the States east of California is based on a canvass of representative producers, who reported to the Geological Survey data, by fields and districts, from which figures indicating approximate average developed acreage per well for the major fields were obtained. The estimated total number of acres was determined by multiplying these factors by the total number of producing wells as reported by companies that operate gathering. lines. For California acreage has been determined in detail by the State Mining Bureau, which reports both developed 13 and proved acreage, but in the absence of detailed surveys, similar data for the rest of the country are not available. Estimated developed petroleum acreage, by major fields, 1923 14 OIL PIPE-LINE MILEAGE The following table was compiled in the spring of 1924 from reports to the Geological Survey from companies operating oil pipe lines. About 141⁄2 million barrels of oil is required to keep the lines filled. Oil pipe-line mileage and capacity, by States SPECIFIC GRAVITY OF CRUDE PETROLEUM The estimated average specific gravity of the crude petroleum produced in certain fields and districts, as reported by pipe-line and producing companies, is given in the accompanying table. The equivalents of degrees A. P. I." in decimals representing specific gravity are taken from "National standard petroleum oil tables" (Circular 154 of the Bureau of Standards). These tables, published in 1924, are the outcome of an agreement among the American Petroleum Institute, the United States Bureau of Mines, and the United States Bureau of Standards to remove the confusion that has existed in the petroleum industry by reason of the use of two socalled Baumé scales for light liquids, one based on the modulus 140 and the other on the modulus 141.5. It has been recommended that only the scale based on the modulus 141.5 be used in the petroleum industry and that it be known as the A. P. I. scale.
