The Baker Hughes North American rig count was down 3 at 802 in the Oct. 18 week from 805 a week ago and fell 20 from 822 a year ago.

The U.S. rig count is down 1 from last week at 585 and down 39 rigs from 624 last year at this time. The Canadian count is down 2 from last week at 217 and compared to last year is up 19 from 198. The Gulf of Mexico rig count is unchanged at 16 in the latest week from last week and down 6 from a year ago.

For the U.S. count, rigs classified as drilling for oil are up 1 at 482, gas rigs are down 2 at 99, and miscellaneous rigs are flat at 4. For the Canadian count, oil rigs are down 1 at 153, gas rigs are down1 at 64, and miscellaneous is flat at 0.

The Baker Hughes North American rig count tracks weekly changes in the number of active operating oil & gas rigs. Used for drilling wellbores for wells that may eventually produce oil or gas, active rigs are essential for the exploration and development of oil and gas fields. Rigs that are not active are not counted. Components in the data are the United States and Canada with a separate count for the Gulf of Mexico (which is a subset of the U.S. total). The count includes only rigs that are significant users of oilfield services and supplies.

Changes in rig counts point to changes in the supply of oil & gas. The higher the rig count, the greater the upward pressure is on oil & gas supply and in turn the greater the downward pressure is on oil & gas prices. The reverse applies when rig counts turn lower, as they did during the oil price collapse of 2014-15 when lower counts contributed to a subsequent decline in domestic oil inventories. Data on the Gulf of Mexico offer indications on production disruptions during the hurricane season (June 1st to November 30th).
