Book Description

Excerpt from Notes on the Oil and Gas Fields of Webb and Zapata Counties: The Underground Position of the Austin Formation in the San Antonio Oil Fields At the present time oil or gas is being obtained from several localities in Webb and Zapata counties. The localities include the Charco Redondo oil wells, Jennings gas pool, and Mirando oil pool in Zapata County, and the Reiser gas wells and Schott oil pool and the gas wells of the Carolina-Texas Oil Company in Webb County. Of these several localities, the Reiser field is the oldest as a commercial field, having been discovered in 1909, although previous to that time oil had been noted in shallow wells drilled for water at the Charco Redondo Ranch. The following notes on the producing fields of these two counties are basedon a reconnaisance of about ten days made in April and May, 1922. Stratigraphic Geology At the March meeting of the American Association of Petroleum Geologists, Dr. A. C. Trowbridge read a paper on the Coastal Plains formations in Texas, adjacent to the Rio Grande, which it is understood, will be published. Not wishing to anticipate in any way the results given in this paper by Trowbridge, the geology and stratigraphy of this area will be referred to at this time only in a very general way. Immediately at Laredo and for a few miles to the east, the rocks exposed in the stream beds and rock cuts are chiefly sandstones, often glauconitic, probably representing the Cook Mountain formation. Next to the east and extending almost, if not quite, to Reiser, is a broad belt in which clays predominate, although some oyster shell beds are included. These clays represent the Yegua formaton.
