EnQuest PLC Announces Update on the Central North Sea drilling programme

Encouraging results from Eagle exploration
ENQUEST PLC, 1 July 2016.

Central North Sea drilling programme

The implementation of EnQuest's 2016 drilling programme in the Central North Sea
has been excellent. Drilling of the Scolty/Crathes development wells was
completed ahead of schedule and under budget. The Scolty reservoir was on
prognosis and the Crathes reservoir exceeded expectations, with a small reserves
upgrade.

In Q2 2016, EnQuest undertook the drilling of an Eagle exploration well on a
100% working interest basis. Eagle was acquired along with EnQuest's other
interests in the Greater Kittiwake Area ('GKA') in 2014. The Eagle exploration
well was completed recently and confirmed as a discovery. Assessment of the
results is underway and preliminary analysis indicates Fulmar oil bearing
reservoir was encountered with a vertical thickness of 67ft and excellent
reservoir properties. Additionally no oil water contact was encountered,
representing potential upside volumes on the flank of the structure. The
encouraging results of the initial analysis lead EnQuest to anticipate gross
total recoverable reserves to be a similar size to those in the nearby Gadwall
producing oil field. Gadwall is part of GKA and was successfully returned to
production by EnQuest in H2 2015; it is estimated that total gross ultimate
recovery from Gadwall will be approximately 6 MMstb. Further evaluation of the
Eagle results is ongoing.

Neil McCulloch, EnQuest's President, North Sea said:

"Drilling performance in the Central North Sea this year has been excellent,
both ahead of schedule and under budget; this builds on EnQuest's outstanding
North Sea drilling performance in 2015, also under budget. I am now also pleased
to confirm that the initial results of the drilling of the nearby Eagle
exploration well have confirmed a new discovery. Following last year's
production growth and unit operating cost reduction successes at GKA, this
latest success demonstrates EnQuest's ability to create value from maturing
assets and from near field exploration opportunities."

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. Its
operated assets include the Thistle/Deveron, Heather/ Broom, Dons area, the
Greater Kittiwake Area and Alma/Galia, also the Kraken and the Scolty/Crathes
developments; EnQuest also has an interest in the non-operated Alba producing
oil field. At the start of 2016, EnQuest had interests in 30 UK production
licences, covering 42 blocks or part blocks and was the operator of 25 of these
licences.

EnQuest believes that the UKCS represents a significant hydrocarbon basin, 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 is replicating its model in the UKCS by targeting previously
underdeveloped assets in a small number of other maturing regions; complementing
its operations and utilising its deep skills in the UK North Sea. In which
context, EnQuest has interests in Malaysia where its operated assets include the
PM8/Seligi Production Sharing Contract and the Tanjong Baram Risk Services
Contract.

The Greater Kittiwake Area: The Greater Kittiwake Area is located in UKCS blocks
21/12a (licence P.073), 21/12d (P.1786), 21/17a (P.1415), 21/17c (P.1415),
21/18a (P.351) and 21/19 (P.238); it includes the Kittiwake, Mallard, Gadwall,
Goosander and Grouse fields. The GKA fields have been developed as subsea tie
-backs to a steel platform located at Kittiwake.
