LLOG Exploration is implementing measures to restore the faulty riser and maintain production at the Who Dat field in the US Gulf of Mexico. After a minor leak was detected in the riser in February, which led to a temporary shutdown of the E manifold, total gross production at the field dropped by approximately 38% compared to the first quarter, reaching 11,360 barrels of oil equivalent per day in the second quarter.
The shutdown of the manifold affected about 15,000 barrels of oil equivalent per day across seven Who Dat wells. Karoon Energy holds a 30% stake in the asset, LLOG (a subsidiary of Harbour Energy) operates the field with a 45% interest, and Westlawn Group owns the remaining 25%.
The joint venture is developing a structured plan to restore the riser. According to Karoon, operator LLOG has informed partners that the next phase will involve dismantling and analyzing the riser, with work scheduled to begin in the third quarter. Production from the E manifold is expected to resume in the fourth quarter of 2027.
To support production until the issue is resolved, a sidetrack well was brought online on July 13. The current base model assumes that one or both E risers will need to be replaced, with production from the E manifold anticipated to restart in the fourth quarter of 2027. The joint venture is also continuing to explore additional opportunities to increase output from the asset.
