LLOG Exploration Initiates Development Studies for Hydrocarbon-Bearing Wells in Gulf of America

U.S.-headquartered privately owned exploration and production company LLOG Exploration has commenced development studies for two hydrocarbon-bearing wells as part of its three-well exploration/appraisal campaign in the Gulf of America (formerly known as the U.S. Gulf of Mexico).

The first well, the Who Dat East appraisal/exploration well, drilled at the end of April 2024, revealed a total net pay thickness of 44 meters measured depth (MD) within the targeted intervals. The joint venture participants for Who Dat East are LLOG (operator, 40%), Karoon (40%), and Westlawn (20%).

Following the success of the Who Dat East well, LLOG is poised to begin drilling the Who Dat South exploration well in the fourth quarter of 2024. Meanwhile, the Who Dat West exploration well, drilled in late December 2025, did not encounter significant hydrocarbon-bearing intervals and has been plugged and abandoned.

Who Dat South Exploration Well

The Who Dat South exploration well, MC 545-1, located near the existing Who Dat FPS and subsea manifold, intersected hydrocarbon-bearing sandstone intervals with an aggregate true vertical thickness of 67 meters. The well has been suspended for potential future production pending JV studies on development options.

Production and Development Outlook

The Who Dat conventional deepwater oil and gas development, operational since 2011, continues to produce oil and gas from nine wells processed through the FPS. Dr. Julian Fowles, Karoon’s CEO and MD, highlighted the production trends and future development plans for the asset.

Despite natural decline rates, production at Who Dat has been sustained through well interventions and optimizations. The gross production in Q4 2024 was slightly lower than the previous quarter due to planned maintenance and shutdowns.

Market Dynamics

The average realized prices for Who Dat liquids and sales gas experienced fluctuations in Q4 2024. While the liquid prices declined, the sales gas prices saw an increase due to seasonal demand and market conditions.

Future Prospects

With the success of the recent drilling campaigns and the potential for value-accretive development opportunities in the Gulf of America, LLOG and its partners are optimistic about the future prospects of the region.

Overall, the ongoing development studies and exploration activities are expected to contribute to the continued growth and success of LLOG Exploration in the Gulf of America.
