Domestic Production - Production in West Texas Permian Basin for 1927

To those who are unfamiliar with the nomenclature in common use among operators in the Mid-Continent, the Permian Basin is a term to cover several widely separated productive areas. It includes what is designated in trade journals as the Panhandle fields, the West Texas fields and Southeastern New Mexico fields. It is bounded roughly on the east by the 100th parallel, on the west by the 104th parallel, 011 thr south by the Rio Grande River and various mountain ranges and on the north by the north line of the Texas Panhandle. The name is derived from the location of these three widely scattered areas which are all in a broad geosyncline which is chiefly filled with sediments of Perrliian age. The oil fields as now known and the approximate limits of the Permian Basin are shown in Fig. 1. The major part of the production in these areas comes from liniestonc or dolomite of Permian age. Some granite wash and sandstone production has been developed but ordinarily does not yield as large initial production as the limestone or dolorliite. Introduction During 1926, Texas, exclusive of the Gulf Coast, produced 12G1SS-1,-952 bbl. of oil,' of which 40,727,877 bbl., or 32 per cent., was produccd in the West Texas Permian Basin. During 1927 the same area in Texas produced 167,176,000 bbl. %f oil, of which 89,779,000 bbL13 or 52 per cent., was produced in the West Texas Permian Basin. The increase in the total production of Texas is about equivalent to the increase in production in the Permian Basin. Since production in the Panliandle District declined during the entire year, the increase of production in the West Texas Permian Basin, and also the increase in Texas, is due to the enormous increase from the West Texas fields. Daily average pl-oduction in the West Texas fields increased from 68,211 bbl. on ,Jan. 8 to
