RNS Number:7817L
EnCore Oil PLC

PRESS RELEASE

For immediate release: 15 January 2008

EnCore Oil plc ("EnCore" or the "Company")

EnCore Acquires Operatorship and Increases Interest in UKCS Block 9/27a

EnCore Oil plc (LSE: EO.) is pleased to announce that it has signed an agreement
with Century Exploration (UK) Limited to increase its equity in UKCS Block 9/27a
from 10 per cent. to 87.5 per cent. In addition to increasing the equity held in
the block, EnCore will be assuming block operatorship. The other co-venturer on
the licence is Granby Oil & Gas plc.

EnCore's interest is subject to a revised overriding royalty of 1.2 per cent.
(previously 2.75 per cent.) of its share of revenues.

This agreement is subject to the usual regulatory approvals.

Alan Booth, Chief Executive Officer, commented:

"EnCore's regional work in this area suggested that there may be overlooked
potential in the block. It is particularly pleasing to see the recent success
announced by Fairfield Energy in adjacent block 9/28. We believe that any
redevelopment of the Crawford field will significantly reduce the threshold for
commercial developments in block 9/27a."

Notes to Editors:

EnCore Oil plc (LSE:EO.) is an oil and gas exploration and production (E&P)
company quoted on AIM.

At EnCore, it is not the Company's aim to build a full cycle E&P company. The
principal strategy is to create shareholder value through the successful
exploration and appraisal of prospects and discoveries. The Company will seek to
monetise or exchange the asset at the appropriate point in its life cycle and
return value directly to shareholders wherever possible.

EnCore has an experienced and proven management team, a number of whom were
responsible for the discovery of the Buzzard field in the UK North Sea, which
currently produces 10 per cent. of the UK's total oil production.

All EnCore's commercial and material technical evaluations are undertaken
in-house by the EnCore team. This brings both continuity to the management and
development of the assets and an ownership that is vital to unearth the best and
most creative new ideas and opportunities.

EnCore currently holds a balanced portfolio of interests in licences both on and
offshore, primarily focused on the UKCS. EnCore expects to participate in the
drilling of nine wells before the end of 2008.
