(Adds natural gas data)
NEW YORK, Sept 30 (Reuters) - U.S. crude oil output fell 276,000 barrels per day (bpd) in July to 11.81 million bpd, its third monthly decline from its record high in April at 12.12 million bpd, according to a U.S. Energy Information Administration monthly report released on Monday.
A majority of the drop in production came as federal offshore Gulf of Mexico production slid about 332,000 bpd to 1.58 million bpd, the data showed.
Output in North Dakota rose by 14,000 bpd to a record 1.41 million bpd while Texas production climbed by 40,000 bpd, rising above 5 million bpd for the first time since the agency began tracking output in 1981.
A shale boom, led by output increases in Texas and North Dakota, helped make the United States the biggest oil producer in the world, above Saudi Arabia and Russia.
However, the rate of growth has slowed this year as U.S. energy firms have reduced the number of oil rigs for a record 10th month in a row as producers follow through on plans to cut spending on new drilling this year.
Meanwhile, monthly gross natural gas production in the lower 48 U.S. states rose to a fresh record high 101.34 billion cubic feet per day (bcfd) in July, compared with a revised 101.19 bcfd in June, according to the EIA’s 914 report.
In Texas, the biggest gas producing state, output increased 1.8% to a record high of 27.96 bcfd from 27.46 bcfd in June.
In Pennsylvania, the second-biggest gas-producing state, output edged higher by 1.9% to 19.09 bcfd from 18.73 bcfd in June. (Reporting by Devika Krishna Kumar in New York Editing by Marguerita Choy)
