The Turtle Bayou-Kent Bayou-North Turtle Bayou Complex

Hershal C. Ferguson, Jr. (1)

ABSTRACT

The Turtle Bayou-Kent Bayou-North Turtle Bayou Complex, located about 65 miles southwest of New Orleans in Terrebonne Parish, Louisiana, consists of three separate fields producing from Middle Miocene strata. The producing structures appear to be two dome-like features south of a regional, east-west trending, down-to-the-south normal fault. As it enters the complex, the regional fault splinters into several separate faults, and on the north side of each of the "splinters", a producing upthrown block is present. The closures developed on the regional fault "splinters" appear to be related to domal growth older than that accounting for the other two producing structures to the south.

Sand development throughout the Middle Miocene is best in upper portions of this interval, for deeper in the section some sands lose the blanket characteristic found in shallower zones and instead exhibit a channel-like configuration. The origin of deposition of any particular potential reservoir sand provides the limitations for the shape and extent of the bed and probably is a controlling factor in hydrocarbon accumulation.
