Canadian Superior Energy Inc. announced, as Operator of the “Intrepid” Block 5(c), that on August 28, 2008, it successfully spudded the “Endeavour” well with the Kan Tan IV semi-submersible drilling rig. The “Endeavour” well is located approximately 5.2 miles north from the recently announced “Bounty” natural gas discovery on the “Intrepid” Block 5(c). As of September 2, 2008, the “Endeavour” well has been spudded (August 28th), successfully drilled to a depth of 1,227 feet subsea where the 30″ surface conductor casing was run and cemented in place; and, the next section of the hole, the 26″ section, has been drilled to approximately 2,305 feet subsea (06:00 EDT).

The “Endeavour” well is planned to be drilled to a total vertical depth of approximately 18,000 feet subsea in about 940 feet of water and is expected to take approximately 100 days to drill. The Kan Tan IV semi-submersible drilling rig, which recently drilled the “Victory” and “Bounty” natural gas discovery wells on Canadian Superior’s “Intrepid” Block 5(c), is drilling the “Endeavour” well, in this initial 3 well program.
