South Timbalier 54 Field

South Timbalier 54 Field

The South Timbalier 54 field is located 36 miles offshore of Lafourche Parish, Louisiana in approximately 67 feet of water on the OCS. The field was originally discovered in 1955 by Humble Oil and Refining and has produced in excess of 153 MMBOE to date. The field is at the confluence of regional and counter-regional fault systems. Pleistocene through Miocene sands are trapped from 4,800 feet to 17,000 feet in shallow low relief structures over a deeper seated salt dome and in combinations of structural and stratigraphic traps against salt at depth. Minor faulting separates hydrocarbon accumulations into individual compartments.

South Timbalier 21 Field

South Timbalier 21 Field

The South Timbalier 21 area is located six to ten miles offshore of Lafourche Parish, Louisiana in approximately 55 feet of water on OCS blocks South Timbalier 21, 22, 23, 26, 27, 28 and 41. The South Timbalier 21 area was discovered by Gulf Oil Company and Shell Oil Company in the late 1950s and 1960s and has produced in excess of 571 MMBOE to date. The field is bounded on the north by a major Miocene expansion fault. Miocene sands are trapped structurally and stratigraphically from 7,000 feet to 15,000 feet in depth. A large counter-regional fault, along with salt and smaller faults, creates traps and separates hydrocarbon accumulations into individual compartments. This field is the tenth largest oil field on the GoM Shelf.
