The number of rotary drilling rigs operating in the United States remained flat this week, Baker Hughes Co. (NYSE: BKR) reported Friday.

Against figures from a week ago, the latest 397-rig U.S. count reflects a one-unit drop in oil rigs (to 305) and a one-unit increase in gas rigs (to 91). Baker Hughes also noted the number of miscellaneous rigs held steady at one.

The total U.S. rig count is down 394 drilling units from last year at this time, Baker Hughes continued. It pointed out that oil rigs are down 374, gas rigs are down 19, and miscellaneous rigs are down one.

Baker Hughes added the U.S. offshore rig count fell by one this week to 16. A year ago, the U.S. boasted 22 operating offshore rigs.
