Narrative
Price of commodity lost was calculated assuming $100/barrel. 3 gallons of crude oil at $100/barrel was less than $10. During the installation of a casing vent to prep a casing for wax filling, a welder was torch cutting a hole in the casing for the installation of a new 2" casing vent. There was at least a 1" gap between the casing and the carrier pipe. While cutting the casing, a flash fire and 3 gallon crude release occurred from an inadvertent burn-through of the carrier pipe. Contractor informed operator about release, but delayed in informing the operator of the fire. Call to nrc was made approximately 30 minutes after operator received notification that a flash fire event occurred. Pipe segment has not been cut out and it is not currently scheduled to be cut out.
