Drillers cut two oil rigs in the week to May 10, bringing the total count down to 805, General Electric Co's Baker Hughes energy services firm said in its closely followed report on Friday.
That put the US rig count, an early indicator of future output, below the 844 drilling a year ago.
The rig count has declined over the past five months as independent exploration and production companies cut spending on new drilling as they focus more on earnings growth instead of increased output.
Major oil companies, like Exxon Mobil Corp and Chevron Corp, however, are boosting their presence, particularly in the Permian, the largest US shale oil field.
The Energy Information Administration this week raised its forecast for US crude output, projecting it would reach a record 12.5 million barrels per day in 2019, and 13.4 million bpd in 2020, up from the current all-time high of 11.0 million bpd.
US crude futures, meanwhile, were trading around $62 per barrel on Friday, leaving the contract little changed for the week as tightened global supplies overshadowed trade tensions stoked by a US move to hike tariffs on Chinese goods.
Looking ahead, crude futures were trading just below $62 a barrel for the balance of 2019, and above $59 in calendar 2020.
US financial services firm Cowen & Co this week said that projections from the exploration and production (E&P) companies it tracks point to a 5 percent decline in capital expenditures for drilling and completions in 2019, versus 2018.
Cowen said independent producers expect to spend about 11 percent less in 2019, while major oil companies plan to spend about 16 percent more.
In total, Cowen said all of the E&P companies it tracks that have reported will spend about $81.9 billion in 2019 versus $86.4 billion in 2018.
Year-to-date, the total number of oil and gas rigs active in the United States has averaged 1,031.
Most rigs produce both oil and gas.
Analysts at Simmons & Co, energy specialists at US investment bank Piper Jaffray, however, forecast the average combined oil and gas rig count will slide from 1,032 in 2018, to 1,019 in 2019, before rising to 1,097 in 2020.
That is the same as Simmons predictions since early April.
