The number of rigs drilling for oil in the U.S. fell by one in the past week to 788, the lowest level since February 2018, according to oil-field services company Baker Hughes.
The nation's gas-rig count declined by five to 181 in the past week, according to Baker Hughes, a GE company.
The U.S. offshore-rig count rose by one from last week at 24 rigs, which is four more than a year ago.
Oil prices were 0.84% higher at $52.71 a barrel in Friday afternoon trading.
The U.S. oil-rig count is typically viewed as a proxy for activity in the sector. After peaking at 1,609 in October 2014, low oil prices put downward pressure on production and the rig count fell sharply. The oil-rig count has generally been rising since the summer of 2016.
