**[Union Jack Oil](https://www.directorstalkinterviews.com/company/union-jack-oil-plc/ujo.l)
plc** ([LON:UJO](https://www.directorstalkinterviews.com/company/union-jack-oil-plc/ujo.l)),
an onshore hydrocarbon production, development and exploration company, principally
focused in the UK, has provided its summary of the Competent Person’s Report for
the Wressle field and Broughton North Prospect, dated 31 December 2023, prepared
by ERC Equipoise Ltd.

The Executive Summary from ERCE’s Report has been published on the Company’s website
www.unionjackoil.com.

Union Jack holds a 40% economic interest in PEDL180 and PEDL182.

**HIGHLIGHTS**

·    263% increase in 2P Reserves compared to 2016 CPR

·    Reclassification of 1,883 mboe in Penistone Flags Contingent Resources to 2P
Reserves

·    59% upgrade to the Ashover Grit and Wingfield Flags Estimated Ultimate Recoverable(“
EUR”)

·    23% upgrade to Broughton North Prospective 2U Resources

**David Bramhill, Executive Chairman of Union Jack Oil commented:** “Based on the
information contained within the Wressle CPR, a 263% increase in 2P Reserves is 
indicated.

“Today’s announcement marks the successful conclusion of the detailed technical 
programme that has been undertaken on Wressle and the wider PEDL180 and PEDL182 
licence areas. This comprehensive programme has involved the reinterpretation of
the reprocessed 3D seismic, integration of the results of the well testing programme
and production data developed in the period to July 2023.

“The additional data and enhanced understanding have led to the material upgrades
in the Reserves of the Ashover Grit, Wingfield Flags and Penistone Flags, and the
increase in Broughton North’s Prospective Resources.

“The increase in Wressle’s Reserves vindicates the focus by the JV partners management
of the field’s production to maximise recoverable volumes. This provides further
support to the development approach we have undertaken to date.

“The installation of artificial lift on the Wressle-1 well marked the start of the
next phase of Wressle’s development, which will also focus on the export of gas 
production to the UK National Transmission System, recently approved by the JV.

“Following the identification of the material increase in Reserves and Resources,
we look forward to 2024 with enthusiasm, where we expect to be able to continue 
to crystallise the potential additional value of Wressle for the benefit of UJO’s
shareholders.”

**Competent Person’s Report**

ERCE has made an independent estimate of the hydrocarbon Reserves and Resources (
Contingent and Prospective) associated with Wressle and the Broughton North Prospect,
located in onshore licences PEDL180 and PEDL182 on the western margin of the Humber
Basin in Lincolnshire.

The CPR was prepared on behalf of the Operator, [Egdon](https://www.directorstalkinterviews.com/company/egdon-resources-plc/edr.l)
Resources U.K. Limited, Union Jack and Europa Oil & Gas Limited.

In the preparation of the Report, ERCE has adopted the June 2018 SPE/WPC/AAPG/ SPEE/
SEG/SPWLA/EAGE Petroleum Resources Management System (“PRMS”) as the standard for
classification and reporting. A glossary of all technical terms used is included
in the Report.

ERCE has produced the CPR as at 30 June 2023 (the “Effective Date”). The Report 
was based on information provided by the Operator up to 24 July 2023, which has 
included updated seismic interpretations and production data.

Estimates of recovery factors were prepared, based on consideration of the results
of production performance analysis, reservoir simulation models, classical reservoir
engineering calculations and the performances of analogue fields. ERCE has derived
independent estimates of Reserves and prepared forecasts of production of oil and
gas.

Production profiles have been generated by ERCE for both Reserves and Contingent
Resources. The forecasts generated for Reserves have then been used as input to 
an economic model to undertake an Economic Limit Test (“ELT”) and assess commerciality.
The economic model has been provided to ERCE by the Operator and has been reviewed
by ERCE to confirm the fiscal regime is correctly represented.

**Broughton North Oil and Gas Prospective Resources**

The Broughton North prospect lies within Licence PEDL180 and is located immediately
northwest of the Wressle field, across a northeast-southwest trending fault. The
majority of the prospect is covered by the same 3D seismic survey that covers the
Wressle field.
