Canadian Superior Confirms Endeavour Well as Natural Gas Discovery

Canadian Superior announced that after extensive preparations, flow testing of the "Endeavour" well offshore Trinidad on the "Intrepid" Block 5(c) commenced on March 1, 2009.

During the initial flowing period of approximately 16 hours, a peak flow rate of 60.1 MMscf/d was obtained, which is the maximum rate allowed under the testing equipment specifications. A final flow rate of 56.4 MMscf/d was measured with a 48/64 inch choke with a FWHP of 4122psi. Multiple flow rate testing will be conducted over the next few days. The well has flowed "dry" natural gas with a gas gravity of approximately 0.584, approximately 0.3% CO2 with no production of water, condensate or solids, during this initial flow period.

The "Endeavour" discovery well was spudded on August 28, 2008 and was drilled by the Kan Tan IV semisubmersible drilling rig in about 1,000 feet of water, which also drilled the "Victory" and "Bounty" natural gas discovery wells on Block 5(c); and is the 3rd well, in an initial 3 well program, being drilled by Canadian Superior and its partners on the "Intrepid" Block, located approximately 60 miles offshore, off the east coast of Trinidad. In 2008, Canadian Superior announced two separate natural gas discoveries on Block 5(c); in the "Victory" well, announced on January 14, 2008; and, in the "Bounty" well, announced on August 13, 2008. "Endeavour" now is a confirmed natural gas discovery; making this program, 3 out of 3.
