...Fred W. Bates; Jay B. Wharton ABSTRACT The West Tepetate oil field, located in the Louisiana Gulf Coast area, was discovered by the Barnsdall Oil Company and Vincent and Welch in 1944. The presence of the structure was first suggested in 1930 by torsion-balance exploration conducted by Vincent...

... was in the Marginulina ascensionensis zone where drilling was stopped as the result of a strong salt water flow. This discovery gives promise of being a good field. The Pure, Shell, and Humble companies are the principal leaseholders. Of major importance is the West Tepetate field, eastern Jefferson Davis Parish...

... miles north of the town of Jennings. The nearest oil field, the Evangeline field, is 12 miles south, although a recently completed distillate well about 10 miles west possibly indicates a new and closer field.

... in the preceeding paragraph are mainly of this latter type. In August, 1935, the Tepetate field was discovered in Acadia Parish, Louisiana. This constituted a new type of feature for the Gulf Coast, with updip closure formed by faulting and with but a minor amount of reverse dip in the area of accumulation...

... deposited in the early-middle Eocene ( Carreno, 2000 ; Garcia-Cordero and Carreno, 2005 ). Therefore, based on the abundance of reworked microfossils in the Tepetate Formation, we infer that it received sediment from Late Cretaceous–early Tertiary forearc strata that were exposed to the west (Fig. 2...

... these circumstances, the tepetate layer is expected to have a medium-low resistive behavior. Figure 6.  Location of the studied area in Mexico. Note that the test profile was deployed within a cultivated zone. The field site studied is called Mezquital Valley. This site has been irrigated...

... the Tamasopo and beneath the Alazan shales in Tepetate, Alamo, etc.; there appearing in the wells in these fields some 100 feet of argillaceous limestone very like the San Felipe in appearance, and usually referred to the San Felipe by geologists. Absolute proof of the age of these beds is lacking...

... the report of Bornhauser and Bates (1938) on the Tepetate field. The producing area is located in the center of a gently domed structure on the downthrown side of a normal fault having several hundred feet of throw. Little or no production is expected from the flanking strata on the higher, upthrown side...

.... 12 miles northwest of Lottie field, another 1948 discovery. Mid-Tepetate (Acadia Parish).—J. C. Hawkins No. 1 Young well, 1 mile west of Tepetate field, completed as new discovery in Frio section June 27. Perforations from 8,530–36′; IP 92 bbls. condensate per day; 1 4 ″ Ch.; Gr. 60.4...

... the production, drops the Woodbine sand to the west along a line east of, and roughly parallel to, the main fault in the southern end of the field. The simple fault system shown in the accompanying figure may in reality be complicated by a number of other minor faults, but the important fault which limits...

... are volcaniclastic, more precisely epiclastic, being mainly composed of volcanic lithic clasts and plagioclase feldspar grains. The Santa Rita–La Presa drainage is developed on the Eocene (Te) to Oligocene (To) marine Tepetate and San Gregorio Formations ( Hausback, 1984 ). The Tepetate was likely derived from...

... areas, including North Tepetate, South Houma, Convent, West Lake Verret, Vermilion Bay, DeLarge, Bayou Baptiste, and Timbalier Bay, have two or less producing wells each at the end of 1939. Four new areas, consisting of West Gueydan, Jefferson Island, Raceland, and Chacahoula, have four producers each...

... Tertiary marine sedimentation of the Tepetate Formation is observed 70 km to the west of La Paz, but this unit thins rapidly to the east and is not present in the region of the Los Cabos block ( Gastil et al., 1979 ; Hausback, 1984 ). The Tepetate Formation is composed of interbedded mudstone and fine...

... has not progressed far enough at Ville Platte to permit a statement as to probable future significance. Call .—The Call field, located along the west line of Newton County, was discovered by the Houston-Republic joint interest on September 22, 1937. The well was completed in Cockfield sands...

... or who may be called upon to do work on the plains and high plateaus of the Southwest? There is a formation in the Southwest, the nature and origin of which is not as well known as it should be. It is known by different names such as caliche, tepetate, surface marl, rim rock, lake marls, scarp rock...
