Summary
Investigation of a well-control incident during recompletion at HI A 443. Inadequate well-control fluid weight and an unavailable hoist prevented timely valve insertion, requiring tubing shearing to shut in the well. Three workers were injured and an estimated 9.34 gallons of oil entered Gulf waters. Training and fluid-weight maintenance are discussed.
