Spills ≥ 50 Barrels (2,100 gallons)1992

January 3, 1992 - Conoco, Inc.

Pollution: 190 bbl Crude Oil Operation: Pipeline
Rig/Platform: Lease: N/A
Area: Block: Grand Isle
41
Cause: Leak
Distance to Shore: 19 Miles Water Depth: 90 Feet
Pipeline Segment: 00630 Pipeline Diameter: 12 Inches

Remarks: On January 3, 1992, a slick was sighted in GI43 field area and reported to the proper agencies. Response: January 4, 1992, the origin of the slick was confirmed to be the pipeline between platform GI43AA and GI47A; divers located the leak and clamps were attached over the section that was leaking. Some contacts to shore about seven miles south of Grand Isle in the Bayou Moreau area, cleanup crews set out booms and picked up oil off the beaches. Conoco brought in two Tri State Bird Rescue experts. Two oiled sandpipers and one lesser scamp were cleaned. The USCG originally estimated volume spilled at 25 bbl, later increased estimate to 190 bbl.


August 31, 1992 - Texaco, Inc.

Pollution: 2,000 bbl Crude Oil Operation: Pipeline
Rig/Platform:   Lease: N/A
Area: Block: South Pelto
8
Cause: Weather Related & External Damage: hurricane
Distance to Shore: 6 Miles Water Depth: 30 Feet
Pipeline Segment: 04006 Pipeline Diameter: 20 Inches

Remarks: Some oil contacts to shore. The damaged portion of the submerged oil pipeline was probably caused by an anchor from rig "Treasure 75" which was moving in a westerly direction caused by high wind from Hurricane Andrew storm. Response: replaced 60' of with ball flange connector on both ends of the line.

NRC Report: 134671


December 26, 1992 - Atlantic Richfield Company

Pollution: 100 bbl Condensate Operation: Drilling
Rig/Platform: Rig Cecil Forbes (jack-up) Lease: G01608
Area: Block: South Pass 60 Cause: Other: insufficient drilling mud weight
Distance to Shore: 4 Miles Water Depth: 187 Feet
Other Events: Loss of Well Control

Remarks: EXPLORATION SPILL. Loss of well control caused by insufficient density of drilling fluid. While the crew was preparing to go back into hole with a core barrel/gun assembly, the well percolated gas with the fluid level dropping, reducing the hydrostatic pressure on the formation. The well began flowing natural gas, condensate and water. Approximately 100 bbl of condensate (part of a water/condensate mixture) flowed into the Gulf of Mexico before the diverter could be closed.
