Title: Deep-Basin Lignite in Northwest Louisiana: ABSTRACT

Author(s): Previous HitHaroldTop D. Nilsson


Analysis of more than 2,000 electric logs has identified at least 63 sites in northwest Louisiana that have potential deep-basin (300-2,500 ft or 91-762 m) lignite deposits thicker than 5 ft (1.52 m). Locations are principally

in Sabine, Webster, and Claiborne Parishes. The distribution of lignite in this depth range is governed primarily by the effects of the Sabine uplift on the Wilcox (Paleocene to Eocene) sediments in which the lignite is concentrated. Additional electric log analysis may reveal deep lignite deposits in other parishes affected by the uplift.

By using underground coal gasification (UCG) processes such as those developed at the Lawrence Livermore National Laboratory and in the Soviet Union, deep-basin lignite could produce low-btu methane suitable as a fuel, or carbon dioxide for enhanced oil recovery.
