PanCanadian Petroleum Ltd., Canada's No. 2 oil company, could soon be on track to develop an East Coast offshore gas project to rival the huge Sable Island project, its chief executive said. PanCanadian, the oil and gas arm of conglomerate Canadian Pacific Ltd., plans to drill two appraisal wells this year near its recent Deep Panuke gas discoveries, made at the site of the exhausted Copan oil project off Nova Scotia. The wells will give the company the geological data it needs to decide whether to pursue more drilling or full development, PanCanadian CEO David Tuer said. Two recent wells drilled into the gas formation beneath the old oil reservoir tested at more than 50 million cubic feet a day each.
