          Endeavour Provides Operational Update on the Rochelle Field

HOUSTON, Feb. 26, 2014 -- Endeavour International Corporation (NYSE: END) (LSE:
ENDV) ("Endeavour" or the "Company") today announced that the valve in the
Rochelle field that had been stuck in the 'shut' position has now been opened
and production is expected to re-commence in the next few days.

Following the tie-in of the East Rochelle E2 well, production from Rochelle
could not be restarted due to a valve on the outlet side of the East Rochelle
production manifold that was stuck in the 'shut' position. A diving support
vessel was mobilized on February 22, 2014 and reported this morning that the
valve had been successfully opened. This was confirmed by the observed pressure
response. The East Rochelle E2 well is expected to be brought on production in
the next few days, followed by the restart of production from the West Rochelle
W1 well.

The Rochelle field came on-line in October of 2013. Endeavour has a 44% working
interest and the field is located in UKCS Blocks 15/26b, 15/26c and 15/27.

Endeavour International Corporation is an international oil and gas exploration
and production company focused on the acquisition, exploration and development
of energy reserves in the North Sea and United States. For more information,
