ENQUEST PLC, 29th May 2013

EnQuest announces its entry into North Africa through a 70% operating interest
in the producing Didon Oil field and the Zarat Permit in Tunisia
EnQuest PLC (together with its subsidiaries "EnQuest" or the "Company") today
announces that it has agreed with Swedish oil and gas company, PA Resources AB
and certain of its subsidiaries ("PA Resources") to acquire a 70% participating
interest in and operatorship of the offshore Tunisian assets of PA Resources,
including 2 MMboe of net producing 2P oil reserves in the Didon oil field and
over 40 MMboe of net contingent resources in the Zarat Field.  A further
programme of 2 infill wells in the Didon oil field should add additional
reserves in the near future.  This acquisition is part of the Company's strategy
to create value from maturing assets and new developments.  PA Resources will
retain a 30% participating interest in the offshore permits and 100% of the
onshore permits.

The acquisition will be effective upon satisfaction of certain conditions
precedent, and involves upfront cash consideration of US$23m payable upon
completion of the transaction. EnQuest has also offered carry consideration of
up to US$93m payable following its sanctioning of the Zarat field development.
Additional consideration of up to US$133m is payable in relation to the
potential developments in the Zarat and Elyssa fields if the capital cost of 2P
reserves is to be no greater than $18/boe, with the top end of the range of such
additional consideration achievable if such capital costs are to be no more than
$13/boe or upon achievement of certain project revenue targets. The maximum
amount of consideration above the initial US$23m completion payment will not
exceed US$226m.

EnQuest's CEO Amjad Bseisu said:

"I am pleased to announce our first international production acquisition giving
us an operating platform in Tunisia. I am also pleased to have PA Resources as a
partner in the Didon oil field and the potential developments at Zarat and
Elyssa, with over 100 MMboe of gross contingent resources and additional
exploration and appraisal opportunities.

This opportunity is ideal for EnQuest and our new partners, allowing us to
deploy our operating and development expertise in these Permits and also adds 2
MMboe of net 2P reserves, 41 MMboe of contingent resources, and approximately
1,000 Boepd net to EnQuest with additional production and 2P reserves coming
from a two well in-fill drilling programme in the Didon field in the near
future."
