BPXA Drill Site 1-Well 11 Pipeline Spill
SITREP # 2
SPILL NUMBER: 12399910102
TIME/DATE OF SPILL: BP Exploration (Alaska) Inc. (BPXA) discovered a pipeline release of freeze protection fluids composed of a 60/40 methanol/seawater mixture and crude oil at Drill Site 1 at 3:20 p.m. on April 10, 2012. The spill was reported to ADEC at 3:50 p.m. on April 10, 2012.
TIME/DATE OF SITUATION REPORT: 5:00 p.m. on April 16, 2012
TYPE/AMOUNT OF PRODUCT SPILLED: BPXA estimated a spill volume of 3,675 gallons, based on the engineered volume of the eight-inch seawater injection pipeline between the manifold building and Well 11. The pipeline contained freeze protection fluids, which consisted of a 60/40 methanol/water mixture, and crude oil. The fluids were released onto the gravel drill pad and into the reserve pit.
INCIDENT LOCATION: BPXA East Operating Area, Drill Site 1, Prudhoe Bay.
CAUSE OF SPILL: The failure occurred during a well warm up procedure conducted in preparation for a mechanical integrity test on Well 11.
POTENTIAL RESPONSIBLE PARTY (PRP): BP Exploration (Alaska) Inc.
RESPONSE ACTION: BPXA completed thawing the frozen pipeline and placed a portable tank under the pipe opening to catch residual fluids. ADEC and Alaska Clean Seas surveyed the spill site and separated it into heavy, medium, and lightly contaminated areas. The area was surveyed and covers approximately 3.85 acres of gravel pad and reserve pit. A six-person Asbestos Abatement Team removed debris and pipe insulation that potentially contained asbestos material. Eight spill response technicians are using hand tools to remove contaminated snow from confined areas of piping.
Work plans are being developed for corrective actions and cleanup tactics, waste management, and confirmation soil sampling.
SOURCE CONTROL: The pipeline is blocked and blinded at the manifold building and at the well.
RESOURCES AFFECTED: Gravel pad and reserve pit.
FUTURE PLANS AND RECOMMENDATIONS: BPXA will continue to remove the contaminated snow, ice and gravel from the drill pad, and the snow and the affected ice within the reserve pit.
