The oil and gas rig count, an early indicator of future output, rose two to 752 in the week to July 8, energy services firm Baker Hughes Co said in its closely followed report on Friday.
Baker Hughes said that puts the total rig count up 273, or 57%, over this time last year.
U.S. oil rigs rose two to 597 this week, their highest since March 2020, while gas rigs were unchanged at 153.
With oil prices up about 39% so far this year to about $104 a barrel after soaring 55% in 2021, the total rig count has grown for a record 23 months.
But weekly rig increases mostly have been in the single digits as many companies focus more on returning money to investors and paying down debt rather than boosting output.
U.S. crude oil production slid in April to 11.6 million barrels per day (bpd), its lowest since February and still far below its record high of 12.3 million bpd in 2019, according to a monthly government report.
In contrast, monthly gross natural gas production rose to 107.3 billion cubic feet per day (bcfd) in April, its highest since December 2021. That compares with an all-time high of 108.2 bcfd in November 2021.
