2012 production and major projects on track.
Unless otherwise stated, all figures are before exceptional items and depletion
of fair value uplift and are in US dollars.

Highlights

  · EnQuest performed well in H1 2012, delivering production of 20,253 Boepd and
revenue of $440m
  · 2012 production is on track for EnQuest’s full year target of between 20,000
Boepd and 24,000 Boepd, with further drilling in the second half, including S10
and S11 coming on stream at Don Southwest
  · Cash flow from operations continued to be strong, with $240m generated in H1
2012
  · Cash capex of $504m was mainly invested in the six well drilling programme
and the procurement and re-fit of the floating, production, storage and
offloading (‘FPSO’) vessel for Alma/Galia
  · Profit after tax increased by 87% to $129m, mainly due to a reduction in
income tax expense compared with H1 2011
  · The Alma/Galia development project is on track for first oil in Q4 2013 as
planned. EnQuest entered into an agreement to farm out 35% of the development to
KUFPEC
  · Significant business development momentum in H1 2012; including agreements
to acquire 60% of the proposed Kraken development, a further 20% of the
Kildrummy discovery, the remaining 50% of the Cairngorm discovery and an
additional 18.5% of the producing West Don field
  · A new credit facility of up to $900m was finalised in Q1 2012

EnQuest CEO Amjad Bseisu said:

“In the first six months of the year, EnQuest made significant progress in
business development, project execution and production. Strong productivity from
Thistle has helped to ensure that our 2012 full year production estimate remains
on target, despite adverse weather conditions in Q1 2012 and third party
pipeline shutdowns in Q2 2012. Our Alma/Galia development is on track and we
entered into an agreement to farm out 35% to KUFPEC. In addition, we are also
working well with our partners to advance the Kraken development to Field
Development Plan (‘FDP’) submission.

In the first half of 2012, we agreed six asset acquisition transactions and
applied for a number of new blocks through the UK’s 27th licensing round. We
have grown our development capability significantly, with employee numbers now
approaching four times the level of two years ago. We will continue to bring
material new development projects to sanction, both from our existing portfolio
of discoveries and new ones, where we aim to be the development partner of
choice.”

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 assets include the Thistle, Deveron,
Heather, Broom, West Don, Don Southwest and Conrie producing fields and the Alma
and Galia development.  At the end of June 2012, EnQuest had interests in 29
production licences covering 36 blocks or part blocks in the UKCS, of which 22
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.
