Structure of the Eastern Portion of the Monroe Gas Field, Northeastern Louisiana

Evidence of east-verging thrust faults is provided by detailed subsurface mapping of the Monroe Gas Rock and overlying formations within Ouachita and Morehouse Parishes, Louisiana. The thrust ramps produce offsets and fault-bend fold patterns in the Monroe Gas Rock. The overlying formations also exhibit folding and offsets, but the folds and offsets generally are not vertically aligned with those found in the Monroe Gas Rock. No evidence of significant normal faulting has been found in the area.

Because the field has experienced repeated periods of exploration and production activity over the last 85 years, the subsurface data set is sufficient to map the structure with significant precision to find stratigraphic duplication in critically located wells.
