The US oil rig count was unchanged at a record high of 1,421. There were four miscellaneous rigs, also unchanged from the week before, according to Baker Hughes data.
The US oil and natural gas rotary rig count for the week fell by seven from last week to 1,959, but it was up 73 from 1,886 in the same week a year earlier.
Canada's rig count rose by 23 week on week to 261, that was also a rise of 21 from 240 in the same week a year ago. Canada's oil rig total was 214, up 19 from the prior week, and its gas rig count was 47, up four.
