Kuparuk 2U Pad Crude Oil Spill

Location: Kuparuk River Field, flow line between 2U Pad and CPF-2. Latitude: N 70° 19' 19.99" Longitude: W149° 55' 41.52".
Time/Date: ConocoPhillips Alaska, Inc. (CPAI) discovered the spill at 1:33 AM on December 16, 2007 and reported the spill to ADEC via the Alaska State Troopers at 2:43 AM.
Spill Id: 07399935001
Product/ Quantity: CPAI reported that 4,284 gallons (102 barrels) of crude oil, gas, and fluids spilled from a 24-inch flow line located within the Kuparuk River field between the 2V and 2W pads.
Cause: CPAI reported external corrosion to the flow line. After the insulation from the flow line was removed, responders observed a 6-inch long crack (about 1/8 inch wide at the center) in the flow line. Investigators believe the cause was from external corrosion due to water trapped between the pipe and the insulation.
