Several important discoveries were made in the San Antonio district during the past year, probably the most important being the Flour Bluff field south of Corpus Christi. La Blanca in Hidalgo County, La Sal Vieja in Willacy County, and Alta Mesa in Brooks County in the Rio Grande Valley area show prospects of important production in sands to a depth of 8,000 feet. More than twenty pools were discovered and as many new productive sands in old and new pools. It is significant that geophysics is an important factor in the discovery of new fields in the coastal area. The Edwards limestone (Upper Cretaceous) well at Pearsall in Frio County, although not a large well, is of unusual importance inasmuch as it extends production in this formation at least 125 miles and has an infl ence on an area of probably 10,000 square miles. Among other important discoveries are pools in Aransas, Calhoun, Duval, and Jim Wells counties.
