Canadian Superior Temporarily Suspends Work at Mariner Well

Canadian Superior Energy reports that well operations at the Canadian Superior El Paso "Mariner" I-85 well have been temporarily suspended due to a large patch of pack ice, located 40 kilometers (25 miles) north of Sable Island, approaching the well site area from the north. Ice concentrations within the patch are at 60% coverage of medium to thin first-year ice of approximately 70 - 120 cm (28 - 47 inches) in thickness. Floe size within the patch range from 10 - 30 m (33 - 100 feet) in diameter.

Mike Coolen, Canadian Superior's Director of East Coast Operations, said, "This is a rare occurrence near Sable Island, but not unknown; and we have been monitoring it very closely. We are well prepared for such an eventuality and have implemented the Ice Management component of our 'Mariner' Block Exploration Well Emergency Response Plan. This situation is under control and all appropriate steps to safe guard the personnel, rig and well are being taken. Appropriate emergency procedures are being fully implemented and the response to this emergency is going well."

On Sunday, March 7, 2004 El Paso and Canadian Superior declared a Level II Severe Weather (Pack Ice) Emergency for the Canadian Superior El Paso "Mariner" I-85 well site. As a precautionary measure, Operations at the Canadian Superior El Paso "Mariner" I-85 well have been temporarily suspended and the well secured. The necessary steps have been taken to remove all personnel from the Rowan Gorilla V drilling rig as a precautionary measure, in a safe and efficient manner; prior to any pack ice encroaching on the site. The "Mariner" Block Exploration Well Emergency Response Plan has been fully implemented and additional vessels, including the Canadian Coast Guard Icebreaker "Terry Fox", which has been dispatched to the site as an additional safety measure, are assisting in implementing the necessary ice management measures to prevent the pack ice from impacting the rig.

Speaking further, Coolen commented, "A full suite of electric wireline logs, Modular Dynamic Tests (MDT's) and a side wall coring program had been completed when the situation arose. This will provide us with additional time to fully evaluate this data. Although difficult to predict the weather with certainty, we would reasonably expect to be back in full operations within the next 7 days, just as soon as the pack ice is no longer a problem. We would expect our insurances to address this business disruption delay."
