Kuparuk 2U Pad Crude Oil Spill



Incident Description
Location Kuparuk River Field, flow line between 2U Pad and CPF-2. Latitude: N 70° 19' 19.99" Longitude: W149° 55' 41.52".
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.
Time/Date of Incident 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.
