Although the salt has not been drilled into, the presence of a typical cap-rock mass of anhydrite and gypsum capped by “lime” rock indicates that Saratoga is a salt dome. The cap rock is elliptical in plan with its major axis about 1½ miles in length and northeast-southwest in strike. The beds penetrated in drilling range in age from Jackson (Eocene) to Pleistocene. The oil is found on a series of lensing supercap sands. Oil was first produced thirty years ago from a shallow well and used for medicinal purposes. The real discovery of the oil field followed shortly after the discovery of Spindletop. The production reached a maximum of 3,000,000 barrels in 1903, and on account of the successive discoveries of new “sands” has fallen off moderately slowly. The crude oil is an 18° Baumé oil with a high content of lubricant stock but also with a rather high content of sulphur. Dates are given in regard to production methods and costs.

Geology of Salt Dome Oil Fields
Coming from an AAPG meeting in 1924, this volume strives to present a comprehensive picture of American salt domes, and to collect and record in permanent form the infirmation that has accumulated during twenty years of exploration for petroleum around the salt domes of the Gulf coastal plain. The plan for the volume included a brief, accurate description of each of the known salt domes. Although the list is not yet quite complete, the facts concerning a number of typical salt domes are presented with sufficient detail to portray +adequately the true nature of this remarkable type of geologic structure. Along with these descriptive papers, and based largely on the data contained in them, are several theoretical and interpretative studies, together, also, with some discussion of European salt domes.
