Approaching the winter drilling season, activity in Western Canada is surging, reports FirstEnergy Capital Corp. Rigs at work grew 10% in mid-October from the week before and 2% from a year earlier, totaling 477 active rigs or 67% of those in the region. If this winter season is as busy as last year, more than 600 rigs will be at work or some 86% of those available, the Calgary-based firm reports. The most active drillers in the region are EnCana Corp., with 50 rigs at work; Husky Energy and Talisman Energy, with 25 each; Devon Energy Corp. and Petro-Canada, 21 each; Burlington Resources, 20; Canadian Natural Resources and Apache Corp., 14 each; EOG Resources, 12; and Anadarko Petroleum, 11. Western Canadian drilling companies' utilization varies. Total Energy Services' eight rigs are all busy and Savannah Energy Services' 19 rigs are also all under contract. Others have some idle rigs: Western Lakota Energy Services reports 93% of 14 rigs are at work; Trinidad Drilling, 84% of 37; Precision Drilling, 68% of 227; Ensign Resource Service, 63% of 147; Patterson-UTI Energy, 59% of 17; and Akita Drilling, 57% of 37. The current rig count of 477 rigs at work is in contrast to as few as 214 at work at this time in 2002; 338 in 2001; 408 in 2000; and 306 in 1999, according to FirstEnergy. Among rigs at work, 71% are rated to drill less than 1,850 meters; 63% to up to 2,450 meters; and 67% to more than 2,450 meters. -Petroleum Finance Week
