West Newton A-2 Update

Union Jack Oil plc (AIM: UJO), a UK focused on-shore hydrocarbon production, development and exploration company notes that Rathlin Energy (UK) Limited ("Rathlin"), the operator of PEDL 183, today communicated the following to local residents as part of its participation in the West Newton Community Liaison group. Union Jack holds a 16.665% interest in this licence containing the West Newton A-1 discovery well and the recently successful West Newton A-2 conventional appraisal well.

"Rathlin mobilised a wireline unit and associated equipment to the West Newton A-2 wellsite today.

"The wireline unit will be used to conduct some logging within the cased wellbore prior to the main phase of the testing operation.

"For safety reasons, Rathlin has enforced the Temporary Traffic Regulation Order, to close the extent of Piper's Lane and Fosham Road along with parts of the footpaths leading to the roads, which has been issued by East Riding of Yorkshire Council. 

"The testing operation is planned to take approximately 4-8 weeks and the road closure will remain in place for the duration of these works"
