Abstract

Paleocene to Eocene-age Wilcox Group which is deeply buried and distributed extensively is the significant oil-bearing reservoir in the deep waters of the northern Gulf of Mexico Basin. The different recognition of Wilcox sedimentary facies existed. In this article, by means of observing cores, analyzing sections and well logging data, we studied on the sedimentary environment and characteristics of the Wilcox group. The result shows that Wilcox group in the deep waters of the northern Gulf of Mexico pertained to deepwater basin-floor fan deposits. The sandstone is very fine to fine-grained arkostic and lithic sandstones. And, we analyzed the provenance of Wilcox and discussed the effect of salt related mini-basin controlling the deposition in deepwater setting. Based on this study, we propose a model for Wilcox deposition, in which the lower slope is defined as channel and there is deepwater fan in basin floor.
