U.S. crude oil output hit an all-time high of more than 11.5 million barrels per day (bbl/d) in October, according to government data released on Dec. 31.
Crude production rose 79,000 bbl/d in October to 11.537 million bbl/d, the U.S. Energy Information Administration (EIA) said in a monthly report. The EIA revised its September oil production figure down by 17,000 bbl/d to 11.458 million bbl/d.
U.S. oil production broke its 1970 record of 10.04 million bbl/d in November 2017 and has set monthly record highs for five straight months since June. The U.S. has become the world's leading crude producer, surpassing Russia and Saudi Arabia.
Production rose to 4.7 million bbl/d in Texas, 1.37 million bbl/d in North Dakota and 772,000 bbl/d in New Mexico. Output in the offshore Gulf of Mexico fell to 1.74 million bbl/d.
Meanwhile, gross natural gas production in the lower 48 U.S. states rose to an all-time high of 96.7 billion cubic feet per day (Bcf/d) in October, up from the prior record of 96 Bcf/d in September, according to EIA's 914 production report.
In Texas, the nation's largest gas producer, production increased to 25.2 Bcf/d, up 0.1% from September. That compares with output of 22.3 Bcf/d in October 2017.
In Pennsylvania, the second-biggest gas producing state, production rose to 17.9 Bcf/d in October, up 1.1% from September. That compares with output of 14.4 Bcf/d in October 2017.
Production cuts have given a sustained boost to U.S. crude suppliers.
Gas supplies have been tight in Southern California for years due to the pipeline limitations and reduced availability of the utility's biggest storage field at Aliso Canyon.
The total oil production from the seven major shale basins in the U.S. was expected to rise 113,000 bbl/d, driven largely by increases in the Permian Basin, the EIA said.
