Structure and Stratigraphy of Rayne Field

Jack W. Shirley (1)


Rayne Field is located in the east central portion of Acadia Parish, Louisiana. The primary production from this field is gas condensate from multiple Frio sands ranging from the Marginulina texana zone to the Nodosaria blanpiedi zone. The important geological significance of this field lies in the pronounced effect on the stratigraphy and structure of two major down-to-the-south depositional faults. Pronounced thickening of the stratigraphic section occurs on the downthrown side of both faults. The faults are of different ages: the northern-most fault on the north flank of the Nodosaria structure being the oldest and influencing the older sediments from Nonion struma time to Nodosaria blanpiedi time, and the southern fault being the southern boundary of Nodosaria production and influencing primarily the younger sediments from Cibicides hazzardi time into Nonion struma time.
