Title: Insoluble-Residue Study of the Holt "Pay," Ector County, Texas: ABSTRACT

Author(s): Taylor Cole, C. M. Linehan

Article Type: Meeting abstract


The Holt "pay" was discovered in the Gulf Oil Corporation's O. B. Holt No. 1 in July, 1939, and is 950 feet below the regular North Cowden pay zone. There has been some controversy as to the age of the Holt "pay." Opinions have varied from Whitehorse to Clear Fork. It is the writers' opinion that the "pay" is middle San Andres in age and is stratigraphically 200 feet below the McKnight "pay" of Crane County and 600 feet above the Tubb "pay" of Crane County.

An interesting comparison is made of various San Andres tops from different companies and their relation with zones below the top of the San Andres are shown. It is the writers' opinion that top of the San Andres is lower than most workers are picking. Three mappable chert zones are found in the San Andres with no appreciable chert occurring above this formation.
