BP Exploration of Alaska Doesn’t Know
Cause of Accident That Injured Worker
Investigation of Explosion at Prudhoe Bay Well A-22
Nov. 25–BP Exploration (Alaska) Inc. officials told the Alaska Oil and Gas Conservation Commission Nov. 14 they’re still working to determine the cause of an Aug. 14 well casing failure on a North Slope production well that caused an explosion and severely injured BP worker Don Shugak.
Preliminary results of the company’s internal inquiry found no evidence that corrosion or drilling operations damaged the casing, according to Tom Gray, Prudhoe Operations Integrity Manager for BP.
“Instead, we believe the pressure in the outer annulus (of the well casing) exceeded the surface casing pressure rating of 5,380 pounds per square inch, due to thermal expansion related to well startup,” Gray told the commission.
Gray explained that as well A-22 in the Prudhoe Bay field was restarted after a shutdown in production, rising temperatures in the well caused fluids in the outer annulus — a space between steel casing, or pipe, inside the well and the outer casing — to expand. This increased pressure beyond the tolerance …
