Who Dat News6 Feb 2026 07:17
This was released by our partner Karoon Energy recently…
Gross Who Dat production in 4Q25 was 2.68 MMboe, 12% higher than 3Q25 (of 2.4 MMboe), reflecting
improved facility uptime of 100%, well uptime of 83%, and the impact late in the quarter of the E6ST well
coming online, which helped partially offset natural reservoir decline. Production for the quarter was 0.65
on an NRI basis, 10% higher than the prior quarter (0.59 MMboe NRI). 2025 full year NRI production was
2.60 MMboe, which was in line with guidance, an improved facility uptime of 100%, well uptime of 83%, and the impact late in the quarter of the E6ST well coming online, which helped partially offset natural reservoir decline. Production for the quarter was 0.65MMboe on an NRI basis, 10% higher than the prior quarter (0.59 MMboe NRI). 2025 full year NRI production was
2.60 MMboe, which was in line with guidance, and compares to 2.90 MMboe for 2024.
The E6 well sidetrack operations, comprising drilling and completing a sidetrack from the E6 wellbore into a
reservoir that is producing in other Who Dat wells, were successfully completed during the quarter. Following
clean-up, E6ST flowed at an initial gross rate of approximately 4,000 bopd plus 2.2 MMscf/d associated gas
(approximately 1,050 boepd on an NRI basis), in line with expectations, prior to natural reservoir decline. The
program was completed under budget.
The average realised price for Who Dat liquids (including oil, condensate and NGLs) was 8% lower than the
previous quarter at US$57.06/bbl, in line with the decline in global oil prices and wider differentials for Mars-
benchmarked crudes. The Who Dat average realised gas price was US$4.29/mcf, up 3% on the previous
quarter, reflecting an increase in Henry Hub benchmark pricing due to early seasonal demand.
Technical studies to mature the A1 production well sidetrack opportunity took place during the quarter, with
activities expected to be completed during 2Q26, subject to Joint Venture approvals.
US GULF COAST - WHO DAT EAST (KAR: 40%), WHO DAT SOUTH (KAR: 30%), OPERATOR: LLOG
Who Dat East FEED studies progressed during the period, based on the preferred development concept of an
initial one well development connected via a subsea tieback directly to the Who Dat production facility. An
application was made in 4Q25 to the US Bureau of Safety and Environmental Enforcement (the US Federal
agency responsible for regulating offshore energy) to receive royalty relief for this development. A decision
on this filing is expected in 1Q26.
The Joint Venture will assess a Final Investment Decision on Who Dat East after the royalty relief decision is
known.
Studies to mature Who Dat South were also progressed, with the Joint Venture aiming to commence a seismic
reprocessing project shortly, to assist with the assessment of potential development options.
