Union Jack Oil has provided a positive update on the extended well test operations at the Wressle Oilfield development, located within licences PEDL180 and PEDL182 in North Lincolnshire, on the Western margin of the Humber Basin.

Union Jack holds a 40% economic interest in this development.

Further to the announcement on 29 July 2021, the coiled tubing operation has been completed safely and successfully and the Ashover Grit reservoir has been returned to flow under well test conditions.

Initial well test measured flow rates, under a restricted choke, have exceeded 500 barrels of oil per day which was the forecast rate following the proppant squeeze operation.

The Wressle-1 well is continuing to clean up and has not yet reached its optimum potential.

Executive Chairman of Union Jack, David Bramhill commented:
"I am, of course, delighted with the outcome of the proppant squeeze operation which has enabled the Wressle-1 discovery to deliver the expected production rate of 500 barrels of oil per day from the Ashover Grit reservoir, the lowest reservoir interval in the original discovery well.

'At a full production rate of 500 barrels of oil per day, Wressle, at current oil prices would transform  the economics of the Company with a materially positive impact on our revenues and operating cashflow.

'Union Jack Management are of the opinion that Wressle is still at a very early stage in its development and that considerable upside potential remains given the higher Wingfield Flags and Penistone Flags reservoirs, that are not part of this test programme, have both already demonstrated their ability to flow oil to surface during testing of the original discovery well, as well as other opportunities within the licence areas.

'We would like to thank Egdon Resources’ (Operator) and their contractors who have contributed to this landmark achievement in obtaining deliverability for the Wresssle Joint Venture and look forward to reporting further details once a stablised flow rate from the Ashover Grit reservoir is achieved in the coming weeks."
