In Canada, Alberta lost four rigs, as did Saskatchewan; Manitoba was down by one, but British Columbia gained two.
The U.S. count ended at 737, just 38% of the year-ago tally. Canada ended at 177, just 42% of the year-ago tally. North America stood at 914 rigs, down 1,428 from a year ago when there were 2,342 rigs running.
