CALGARY, ALBERTA--(Marketwire - Dec. 8, 2008) - Canadian Superior Energy Inc. ("Canadian Superior", the "Company") (TSX:SNG) (AMEX:SNG) announced today that Canadian Superior, along with its partners, BG International Limited ("BG"), a wholly owned subsidiary of the BG Group plc (LSE:BG.L) and Challenger Energy Corp. ("Challenger") (TSX VENTURE:CHQ) (AMEX:CHQ), having drilled the "Endeavour" well offshore Trinidad to a depth of approximately 16,921 feet subsea in the final section of the well, have temporary ceased drilling while part of the Kan Tan IV's drilling equipment, the travelling block, undergoes a mechanical repair. It is expected that the repair will be completed this week and drilling in the final section of the well will re-commence.

Speaking today, Mike Coolen, Canadian Superior's President & CEO, said, "This mechanical failure of the rig's drilling equipment is untimely and regrettable; particularly, as drilling had progressed to within a few days of reaching the expected final total depth (final "TD") for the well. We expect the rig owner, Sinopec Corp., and their managing contractor, A. P. Moller - Maersk A/S, to safely and efficiently complete this repair with essentially $0 daily rig rate and for the rig to get back to drilling promptly towards the end of this week, so that the drilling and evaluation of the "Endeavour" well can be properly completed."
