               Endeavour Announces Rochelle Field Offline

Revises Third Quarter Physical Production Guidance

HOUSTON, Sept. 15, 2014 -- Endeavour International Corporation (NYSE: END) (LSE:
ENDV) today announced that the Rochelle field is offline until repairs to the
dry gas export compressors on the Scott platform are completed.

In August, the previously announced planned shutdown of the Scott platform and
Forties Pipeline System was completed and the Rochelle field returned to
production on August 26, 2014. Production rates had ramped back up to over 100
million standard cubic feet of gas per day ("MMscf/d") before Rochelle was
shut-in on September 9, 2014 because of a mechanical problem on the Scott
platform. The Scott platform shutdown was caused by a failure of the export gas
compressor and repair work is ongoing. Endeavour has been informed by the
operator that production from the Rochelle field is expected to be back online
later in the month. Endeavour has a 44% working interest in the Rochelle field.

As a result of the unplanned downtime at the Rochelle field, the Company is
revising its third quarter 2014 guidance down 500 barrels of oil equivalent per
day ("boepd") to 9,000 - 10,000 boepd.

Endeavour International Corporation is an oil and gas exploration and
production company focused on the acquisition, exploration and development of
