Sparta-Wilcox Trend, Texas and Louisiana

Abstract

The major portion of this recently revived productive trend in the lower Eocene of the upper Gulf Coast of Texas and Louisiana is considered to lie between the -5,000-foot contour on the north and the -10,000-foot contour on the south. Sand conditions are such that this trend may be comparable in productive possibilities with the other major producing trends of the Gulf Coast. The sands of the Cook Mountain formation and Wilcox group have come into recent and increasing importance as oil reservoirs. The purpose of this paper is to sketch briefly our present knowledge of this portion of the Eocene, to point out the possibilities, and to suggest some of the problems of the productive zone. It is hoped that this will prove informative to those not acquainted with the Sparta-Wilcox trend, and that it will provoke comment from those more familiar with the facts than the writers.
