That was 642 rigs, or 71.5%, below this time last year.
That total rig count fell to a record low of 244 rigs during the week ended Aug. 14.
U.S. oil rigs rose one to 181 this week, while gas rigs remained unchanged at 72, according to Baker Hughes data.
Even though U.S. oil prices are still down about 34% since the start of the year due to coronavirus demand destruction, U.S. crude futures have gained 140% over the past four months to below $40 a barrel on Friday mostly on hopes global economies and energy demand will snap back as governments lift lockdowns.
Analysts said those higher oil prices have encouraged some energy firms to start adding units.
Most firms, however, still plan to keep cutting costs.
U.S. financial services firm Cowen & Co said the 45 independent exploration and production (E&P) companies it tracks plan to slash spending by about 47% in 2020 versus 2019. That follows a capex reduction of roughly 9% in 2019 and an increase of around 23% in 2018.
Cowen also said that some E&Ps issued early estimates for 2021 that so far point to 8% drop in spending next year versus 2020.
