Endeavour Announces Rochelle Field Offline

-- Revises Third Quarter Physical Production Guidance

HOUSTON, Sept. 15, 2014 /PRNewswire/ -- 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.
