Canadian Superior 'Optimistic' at Trinidad's Endeavour Well

Canadian Superior Energy Inc., as Operator of the Intrepid Block 5(c), has successfully drilled the 26" hole section of the well and has run and cemented in place the 20" casing string to a depth of 3,030 feet subsea.

The Endeavour well was spudded on August 28, 2008 and, as reported previously, the 36" surface hole section was drilled successfully and the 30" surface conductor casing was run and cemented in place. Following necessary drilling operations, including the installation of the marine riser and the blowout preventer (BOP), drilling will re-commence. The next section of the well to be drilled will reach just over 5,000 feet subsea.

Speaking today, Craig McKenzie, Canadian Superior's Chief Executive Officer, said, "I am pleased to report our good drilling progress at Endeavour. Considering the significant exploration success we have already achieved on Intrepid Block 5(c), we are excited to be drilling Endeavour and are optimistic that it will meet expectations. As in the previous wells, the Endeavour targets a large separate structure determined from the analysis and evaluation of extensive 3D seismic. The primary objective includes proving up higher pressure horizons like seen in Bounty with a secondary objective including at least one of the productive horizons penetrated in the Victory well."

The Endeavour well is planned to be drilled to a total vertical depth of approximately 18,000 feet subsea in about 1,000 feet of water and is expected to take approximately 100 days to drill. The Endeavour well is being drilled by the Kan Tan IV semisubmersible drilling rig, which drilled the Victory and Bounty natural gas discovery wells on this block in this initial 3 well program.
