Baker Hughes published its monthly report on global rig counts. The data reflect the number of rigs actively exploring for oil or natural gas.
The oil services company said there were an average 1,861 rigs active in the United States in June, up two from the number counted in May but up 100 from June 2013.
For Canada, Baker Hughes said the average rig count for June was 240, up 78 from May and 57 more than were counted in June 2013.
North American production is increasing to the extent its markets are relying less on energy imports from outside the region. The Paris-based International Energy Agency in June said global oil supplies rose largely because of output from countries outside the Organization of Petroleum Exporting Countries.
Baker Hughes said that outside North America, the average rig count for June was 1,336, down 14 from May but up three from the number counted in June 2013.
