Operations, expected to resume during late 2024, followed “major site upgrades” during last year and 2025.
“The newly installed equipment and facilities are working well and continue to be fine-tuned to optimise production,” said the company.
Union Jack added that during June 2025, Keddington produced 992 barrels of oil over 23 days of timed pumped production, averaging 10.4 hours per day with an average flow rate of 43 barrels per day gross during the period.
“As expected, current flow rates from Keddington are exhibiting a material increase in oil production to those seen prior to the site upgrades,” said executive chairman David Bramhill.
“Over 1,450 barrels of high-quality oil have now been produced and sold from Keddington since recommissioning.”
The company holds a 55% interest in Keddington and Egdon Resources (UK) Ltd owns 45%.
Union Jack’s other interests are the onshore Wressle JV (40%) and Oklahoma, USA.
