Developments in South Texas in 1947

Abstract

Development in the South Texas district during 1947 showed a 26 per cent increase over the previous year. In all, 2,386 tests, 1,758 wells in proved areas and 528 wildcat wells, were drilled and resulted in 1,541 successful completions. The exploratory development resulted in the discovery of 63 new producing areas, the Bloomington field of Victoria County and the Cam field of Duval County being the outstanding discoveries of the year. Wells drilled in productive areas uncovered 151 new producing zones, the Frio-Vicksburg trend accounting for 112. The new producing zones in old fields are probably of greater reserve importance than the new fields discovered in 1947. At the close of 1947, 15,775 oil wells in South Texas had produced 154,179,726 barrels of oil, 11 per cent ore than that of the previous year, and gas transmission lines had marketed 140,227,866 MCF of gas well gas and 5,980,000 MCF of casinghead gas. Seventy-six per cent of the oil produced in South Texas comes from fields of the Frio-Vicksburg trend.
