** EBITDA is calculated by taking profit/loss from operations before tax and
finance income/(costs) and adding back depletion (adjusted for depletion of fair
value uplift), depreciation, impairment, write-off of intangible oil and gas
assets and foreign exchange movements.  This foreign exchange adjustment for
2013 is a change to the definition used previously and the prior year EBITDA
figure has been restated accordingly.   *** Net (debt)/cash represents cash and
cash equivalents less borrowings as at the reported cash flow statement date of
31 December.

EnQuest CEO Amjad Bseisu said:

"EnQuest has delivered another good year of growth in production and a
significant increase in reserves, supported by strong cash flow.  Production
growth of over 6% represents an excellent operational and reservoir performance
from our existing assets, particularly in the second half.

Companies like EnQuest are the future of the UK North Sea.  Having strong and
technically focused operations gives us the ability to maximise hydrocarbon
recovery.  Our objectives are fully aligned with the goals and the
recommendations of the recent Wood Review. Our business model is sustainable and
is set to deliver a material increase in cash flow from operations over the
coming years."

Summary and 2014 Outlook

2013 was another good year of delivery and progress for EnQuest.  We continue to
demonstrate that by targeting maturing assets and undeveloped oil fields, we can
create value and deliver sustainable growth.

In 2014, EnQuest will continue to invest in its current producing assets, bring
Alma/Galia onstream, integrate the Greater Kittiwake Area ('GKA') acquisition
and make substantial investments in the Kraken development, with Kraken
scheduled to come onstream by 2017.  We are therefore on course for having six
producing operated hubs in the UK and for achieving our objective of annual net
production from the UK North Sea of around 50,000 Boepd.  Beyond that, we are
creating further new potential from our UK asset portfolio and making low cost
investments in international opportunities, securing EnQuest's growth for the
longer term.

  ·   Production guidance: Average production guidance for the full year 2014 is
an increase to between 25,000 Boepd and 30,000 Boepd, this excludes production
from Didon in Tunisia, as the acquisition has not completed.

  ·   Drilling programme: EnQuest plans to deliver over 15 wells in 2014.  The
drilling programme includes a new production well on Don Southwest, a workover
of a production well on GKA, an ongoing intervention programme on Thistle, three
production wells and one injection well on Alma/Galia and the recommencement of
drilling on Heather for the first time since 2006, with two sidetracks and two
workovers.  Two production wells are also planned for the non-operated Alba.

  ·   Exploration and appraisal: The 2014 exploration and appraisal drilling
programme includes wells on Cairngorm, a Kraken satellite and Avalon in the UK.
 Internationally, in H2 2014, a non-operated well is being matured for drilling
in the Sabah area, offshore Malaysia.

  ·   Assessment of the results of the Cairngorm appraisal well is underway;
preliminary analysis indicates a 173ft hydrocarbon column was encountered, with
evidence of good reservoir properties in the fractured granite.  With the
results of the previous well and seismic, the overall indications in the
structure are now of a total hydrocarbon column of 797ft.  Further evaluation is
ongoing.

  ·   Development opportunities:  Scolty/Crathes: Following the acquisition of
the GKA assets and the planned drilling of Avalon, options for a proposed
Scolty/Crathes development will be assessed. Don North East: Within the first
twelve months of the licence, it is intended to submit a field development plan
('FDP') in relation to Area 24, to include at least one production well.

  ·   Capital and operating expenditure: In 2014, capital expenditure on current
projects is expected to be approximately $1 billion with approximately $400
million being invested in the Kraken development and approximately $200 million
in Alma/Galia.  Production and transportation costs for 2014 are expected to be
in the range $415 million to $435 million, including c.$60 million for GKA and
c.$25 million for Alma/Galia.

  ·   Tax: The effective tax rate for 2014 is expected to be approximately 60%,
based on current oil prices; with continuing investment in the North Sea no
material cash tax is expected to be paid on UK operational activities before
2020.

By Production and Development Asset

Thistle/Deveron

  ·  In 2014, capital investment is continuing in the Thistle life extension
project; ongoing activities include; a control systems upgrade and significant
simplification of processes, jacket integrity improvements and topsides
structural integrity improvements.

Don fields

  ·   Production optimising projects continue on the Don fields, with a new
production well planned to be drilled in H1 2014 in Don Southwest.

  ·   In Q1 2014, EnQuest applied for and was offered an 'out of round' licence
('Don NE') in the Don North East area for blocks 211/18e and 211/19c, including
the Area 23 and Area 24 discovered oil accumulations and an undrilled extension
to the Don NE field.

Heather/Broom

  ·   Following the completion of the rig reactivation project, rig operations
commenced in Q1 2014 with a workover of the H56 well, due onstream in H1 2014,
to be followed by the sidetrack of H44 as a new injection well in the B2 block.
The 2014 programme also includes a sidetrack of H48 and a workover of the
crestal E-Block producer H47.

  ·   The Heather life extension project includes a three year infill drilling
campaign; there are nine wells in the initial programme, targeting 12 MMboe
reserves which are included in net 2P reserves.

Alma/Galia

  ·   Drilling and completion operations continue ahead of production start-up.
The field is set to generate a material increase to EnQuest's net production,
with initial net peak production of c.13,000 Boepd. Production start-up is
anticipated in H2 2014.

Kraken

  ·   In Q2 2014 the vessel to be converted to the Kraken FPSO will arrive at
the shipyard in Singapore for the conversion scope to commence. Further
appraisal drilling will be undertaken on a satellite to the west of the Kraken
field in Q3 2014 to assess the upside potential of the field.  Contracts for
over 60% of the project have now been signed.

Greater Kittiwake Area

  ·   Following completion of the acquisition in Q1 2014, EnQuest has taken over
as operator, an early workover programme is planned in 2014 and an assessment of
exploration opportunities in the area.  EnQuest has a working interest of 50% in
GKA, with an overall decommissioning liability of approximately 25%.

Further business development in Q1 2014

Norwegian North Sea

  ·   In January 2014, EnQuest was offered and accepted two licences in the
Norwegian 2013 Awards in Pre-defined Areas ('APA') licensing round, both located
in the Norwegian Sea.  EnQuest was offered production licence 758 ('Rosslyng'),
with EnQuest as the operator and having a 35% interest.  EnQuest was also
offered licence 760 ('Chinook'), with Total as the operator, both Total and
EnQuest having a 50% interest each. In both cases, the work commitments in the
initial two year period entail 3D seismic licensing and reprocessing.

Review of 2013
Financial

  ·   Strong levels of cash generation continued, with EBITDA of $621.3 million
and cash generated from operations of $562.7 million.  Net debt was $381.1
million at the end of 2013, after cash outflow of $984.3 million on capital
expenditure.  Cash generated from operations is slightly lower than the prior
year mainly due to costs associated with the new financing facilities put in
place in 2013.

  ·   Tax losses increased to $1,087 million at the end of 2013, reflecting the
investment programme.

  ·   2013 revenue of $961.2 million was 8.1% higher than in 2012, mainly due to
the increase in production, partly offset by the decrease in the realised
average price per barrel of oil sold.  There was a slight increase in revenue
for 2013 due to an overlift of $2.6 million in 2013, compared to an underlift of
$24.4 million in 2012.

  ·   Profit from operations before tax and net finance costs was $374.8
million, a 7.5% decrease over 2012.  This reflects the $84.1 million increase in
the cost of sales, partly due to a $27.2 million change in the lifting position
and also to an increase in transportation costs.  Production and transportation
costs increased due to increased production volumes, including those from the
Alba acquisition, but primarily due to an increase in costs per barrel at the
Sullom Voe terminal.  Unit production costs of $27.2 per barrel were flat
compared to the $27.4 per barrel equivalent costs incurred in 2012.

  ·   Profit after tax of $193.1 million was 25.6% lower than 2012 due to a
higher effective tax rate as a result of higher tax benefits in 2012.

  ·   In 2013, $984.3 million of cash capital expenditure was invested for the
future growth of the business; $460.5m was invested on the Alma/Galia
development and $171.5m on the Kraken development, with approximately $295m
invested on the existing producing fields.

  ·   In 2013, EnQuest put in place a new credit facility for up to $1.7 billion
and issued retail bonds totalling £155 million.

*Net production since the completion of the acquisition at the end of March
2013, averaged over all of 2013.

Thistle/Deveron

  ·   Production at Thistle/Deveron achieved a net 7,925 Boepd in 2013, with a
particularly strong performance in the second half of the year, with peak rates
over 16,000 Boepd.

  ·   In H2 2013, production benefitted from strong performance from a new
production well which came onstream at the start of August.  Thistle's new D
turbine and fully rebuilt B turbine are resulting in significantly improved
power supply stability. Despite a two week scheduled platform shut down for
maintenance in October 2013, production in the second half of 2013 was almost
double the levels in the first half.

Don fields

  ·   Production at the Don fields achieved a net 11,014 Boepd in 2013, ahead of
the 10,992 Boepd produced in 2012.

  ·   Production benefitted from the West Don W6/W4 producer/injector pair,
following the tie in of the W6 injector  well in Q1 2013.  The Don South West
Area 6 producer, S12Z, was completed and brought onstream in June 2013, followed
by Area 6 injector, S13, in August.  Operational performance highlights in H2
2013 included a record water injection rate of 58,000 bwpd.

Heather/Broom

  ·  Production at Heather/Broom achieved a net 4,339 Boepd in 2013, up 15.6% on
2012, reflecting good well performance at Broom and improved operating
efficiency at both Heather and Broom.  An improvement in Heather operating
uptimes was achieved partly as a result of extensive work on the gas lift
compression system.  The Heather rig reactivation project was successfully
completed in H2 2013, with commissioning in early 2014.

Alma/Galia

  ·   In February 2013, EnQuest announced that it had approved an increase in
the scope and specification of the Alma/Galia project with the objective of
extending the field life, optimising operating costs and enabling a second
phase.  The extension of the field life increased gross 2P reserves to 34MMboe.

  ·   The EnQuest Producer is now at a yard on the Tyne to undertake finishing
yard scope and onshore commissioning.

  ·   By the end of 2013, subsea infrastructure was in place including trees,
pipelines, umbilicals and manifolds.  Risers and mooring systems were pre
-installed awaiting arrival of the EnQuest Producer FPSO.  The first electrical
submersible pump ('ESP') was successfully installed on Alma on Well K2, followed
by the installation of the second ESP, in well K3.

Kraken

  ·   In H1 2013, an appraisal well confirmed a second accumulation of oil north
of Kraken. In H2 2013, the Kraken Field Development Plan ('FDP') was approved by
the Department of Energy and Climate Change ('DECC') and sanctioned by EnQuest
and its partners.  At the time of project sanction, the major supplier
arrangements were already in place, including those for the FPSO vessel. First
production is anticipated in 2016/2017, with gross peak production of over
50,000 Boepd. Following the project's sanction, EnQuest has added over 60 MMboe
to its net 2P reserves.

Reserves

  ·   Audited net 2P reserves at the start of 2014 were 194.8 MMboe, a 51.6%
increase on the start of 2013; reflecting a reserves replacement ratio of over
850% and a reserve life of over 20 years.  Net 2P reserves include 7 MMboe that
will be consumed as lease fuel on the Kraken and Alma/Galia FPSOs.

Notes to editors
EnQuest is the largest UK independent producer in the UK North Sea.  EnQuest PLC
trades on both the London Stock Exchange and the NASDAQ OMX Stockholm.  It is a
constituent of the FTSE 250 index.  Its operated assets include the Thistle,
Deveron, Heather, Broom, West Don, Don Southwest, Conrie, Kittiwake, Mallard,
Gadwall, Goosander and Grouse producing fields and the Alma/Galia and Kraken
developments; EnQuest also has an interest in the non-operated Alba producing
oil field.  EnQuest had 31 UK production licences at the start of 2014. This
increases to 37 production licences with the inclusion of the assets from the
acquisition of the Greater Kittiwake Area which completed in Q1 2013 and the Don
North East area licence which was offered 'out of round' to EnQuest in Q1 2014;
these licences cover 47 blocks or part blocks in the UKCS, 30 of the licences
are operated by EnQuest.

EnQuest believes that the UKCS represents a significant hydrocarbon basin in a
low risk region, which continues to benefit from an extensive installed
infrastructure base and skilled labour.  EnQuest believes that its assets offer
material organic growth opportunities, driven by exploitation of current
infrastructure on the UKCS and the development of low risk near field
opportunities.

EnQuest has begun replicating its existing model in the UKCS by targeting
previously underdeveloped assets in a small number of other maturing regions;
complementing our operations and utilising our deep skills in the UK North Sea.
In which context, EnQuest also has interests in two blocks offshore Sabah, in
Malaysia and an interest in the Northwest October concession in Egypt.
