Canadian Superior Temporarily Suspends Drilling at Mariner W

Canadian Superior reported that on Tuesday, February 17, 2004, the Rowan Gorilla V is conducting regular drilling operations at the Canadian Superior El Paso "Mariner" I-85 well, in the 216 mm (8 1/2 inch) hole section of the well. The Total Vertical Depth (TVD) achieved to date is approximately 5,027m (16,493 feet).

When contacted in Halifax, Mike Coolen, Canadian Superior's Director of East Coast Operations, said, "Everything is going extremely well; but, we did need to temporarily suspend drilling on Thursday February 12, 2004 to address an obstruction in the well bore caused by a defective wellhead component. This potentially serious situation was addressed swiftly in a safe and efficient manner; and drilling operations recommenced on Monday, February 16, 2004 following equipment inspection and repair. We expect it will take the drill bit less than 2 more weeks to drill this well to its minimum targeted total depth of approximately 5,600 meters (18,370 feet) at a total budgeted cost of U.S. $30 million. Testing and evaluation of the well will take place upon the well reaching total depth and could take approximately another two weeks thereafter to complete."
