Canada's rig count jumped by 58 to 382 this week, up strongly from 289 last year.
In the US, the number of rotary rigs drilling for oil declined by 9 to 133, while drilling for natural gas increased by 6 to 711.

Worldwide, drilling contractors registered a net increase of 4 mobile offshore rigs under contract to 544 out of a total fleet of 656. That raised global utilization of mobile offshore rigs to 82.9%
