North Sea

Amjad Bseisu, Chief Executive, said

EnQuest continues to deliver on our targets with a successful 14 well programme
for 2012. Our execution in all of our major programmes at Thistle, the Dons and
Alma is on track, which is a testament to the skills and technical strength of
our people.  Our financial performance, production and cash generation are on
track for another strong year. The execution of our major development projects
Alma and Kraken will secure our medium term production and reserves growth.

We have also announced today our first steps outside of the UK North Sea,
preparatory moves to replicate our existing model 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.

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.
