Union Jack Oil Gaffney Cline report update

Union Jack Oil

Union Jack Oil plc (LON:UJO) a UK focused onshore hydrocarbon production, development and exploration company, has provided an update on the Gaffney Cline report in respect of the Wressle hydrocarbon 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 the Wressle development.

The Gaffney Cline report has been commissioned and paid for by Union Jack.

Gaffney Cline were originally commissioned to prepare a Competent Persons Report (“CPR”).

Over the course of the initial preparation of the CPR, particularly given the receipt of further positive information in respect of downhole pressures and the continued elevated production figures from Wressle-1, the decision was made to expand the scope of work from a CPR to a wider Reserves and Resources Report prepared in accordance with the Petroleum Resources Management System (“PRMS”), a standard developed by the Society of Petroleum Engineers.

The additional reporting in the expanded scope of work for the Gaffney Cline report will incorporate:

·    1P/2P/3P reserve values for the Ashover Grit and Wingfield Flags reservoirs

·    Highlight and discuss any additional potential reservoirs

·    Generation of an indicative 2C profile for the Penistone Flags reservoir

·    Preparation of a 2P+2C profile illustrating future field potential

Executive Chairman of Union Jack, David Bramhill commented: “Wressle continues to outperform over and above original prognosis and expectations.

“We are confident that the expanded Gaffney Cline report will assist in highlighting the true upside potential of this economically attractive conventional hydrocarbon development.

“Union Jack looks forward to sharing the results of this report once received.”
