Endeavour Provides Rochelle Drilling Update  
HOUSTON, Feb. 14, 2013 -- Endeavour International Corporation (NYSE: END) (LSE:  
ENDV) ("Endeavour" or the "Company") today announced a drilling update on the 
Rochelle well (15/27-E1y) in the U.K. Central North Sea.   
Following a severe storm lasting several days, the Company performed a routine 
inspection of the conductor, well head and blow out preventer systems using a 
Operated Vehicle (ROV). Inspection of the well revealed that the cement around 
top of the 36" conductor pipe, that anchors the well to the seabed floor, had 
removed creating a non- uniform hole around the conductor. The hole extended 
approximately 4 to 7 feet in diameter and 25 feet in depth. 
As a result of this finding, drilling operations have been suspended on the 
Rochelle well. The Company is conducting a thorough analysis to identify the 
of the cement loss and evaluate if there has been any potential fatigue damage 
the conductor itself. The work to repair the cementing around the conductor 
pipe has 
been completed.   
Preparations are now being made to move the Transocean Prospect rig to the West  
Rochelle area to commence drilling of the second production well, allowing for 
start- up of the Rochelle development.  The time to drill the West Rochelle 
production well is estimated at approximately 120 days. 
Once the investigation and fatigue analysis are concluded, the Company 
that drilling operations will re-commence at East Rochelle. Endeavour is the 
operator of the Rochelle development and has a 44% working interest in the 
located in Blocks 15/26b, 15/26c and 15/27.
