Endeavour Shows Significant Progress in 3Q 2012 (USA)

Endeavour International Corporation today, November 1, reported third quarter 2012 Adjusted EBITDA of $51.6 million compared to $2.4 million for the same quarter of 2011. On a GAAP basis, for the third quarter of 2012 net loss was $33.7 million as compared to net loss of $63.3 million for the same quarter in 2011.

Production for the quarter ending September 30, 2012 was up 370% from the comparable quarter in 2011, with U.K. crude oil accounting for 100% of the increase. For the first nine months of 2012 compared to the same period in 2011, sales volumes increased 215% from U.K. crude production. For the third quarter 2012, entitlement production averaged approximately 10,700 barrels of oil equivalent per day (“boepd”) compared to actual sales volumes for the period of approximately 11,000 boepd.

Business highlights include:

North Sea:

– At Rochelle, the installation of subsea pipelines and umbilicals has been completed ahead of schedule

– The first of the two planned production wells was drilled to a final casing point

– Awarded seven licenses covering ten exploration blocks in the U.K.’s 27th Licensing Round around existing core areas

“The Company enjoyed significant progress in the third quarter with strong increases in Brent priced crude oil production in the U.K. North Sea. We are focused on and making great progress to deliver first production at our Rochelle development,” said William L. Transier, chairman, chief executive officer and president. “For health and safety reason, drilling and infrastructure implementation cannot occur in the same area simultaneously. By making the difficult decision to suspend drilling before final completion, we were able to keep our service contractor on schedule to complete the necessary subsea infrastructure. This decision preserves the option to achieve first production at Rochelle in early 2013.”

The contracted rig at Rochelle, the Diamond Ocean Nomad, completed the drilling on the first of two planned development wells to the final casing point before moving the rig off location to allow for the hook-up of the pipelines and flow-lines to the subsea manifolds. Final drilling and completion of this first development well will be done by the Transocean Prospect which is scheduled to arrive in field in December. Due to the change in the timing of completion of the first well, first production at the field is now expected in January 2013 assuming the rig arrives as scheduled. The Rochelle subsea infrastructure installation has been substantially completed. Endeavour is the operator of the Rochelle development project and holds a 44% ownership interest in the Rochelle development which is comprised of Blocks 15/26b, 15/26c and 15/27.

During the 27th Licensing Round, the U.K. government awarded the Company seven new licenses, covering ten exploration blocks located around existing core areas. All the licenses, which have a traditional four year term, will be operated by the Company and offer additional growth opportunities in the future. There are no firm well obligations on any of the licenses and minimal upfront capital commitments.
