NEW YORK, Nov 29 (Reuters) - U.S. crude oil production in September rose to a new record of 12.46 million barrels per day (bpd) from 12.397 million bpd in August, the U.S. government said in a monthly report on Friday.

The United States has become the world’s largest oil producer as technological advances have increased production from shale formations.

Oil output in Texas rose 72,000 bpd in September, while production in North Dakota and the Gulf of Mexico fell during the month. Production also climbed in Oklahoma and Alaska.

U.S. gasoline demand fell 652,000 bpd in the month to 9.2 million bpd. U.S. demand for distillate fuels, including diesel, fell 87,000 bpd to 3.9 million bpd, according to the report.

Meanwhile, monthly gross natural gas production in the lower 48 U.S. states rose to an all-time high of 104.8 billion cubic feet per day (bcfd) in September from the prior record of 104.2 bcfd in August, according to the EIA’s 914 report.

In Texas, the biggest gas producing state, output increased 1% to a fresh record high of 29 bcfd in September.

In Pennsylvania, the second-biggest gas-producing state, output rose 0.1% to a record 19.24 bcfd in September from the prior all-time high of 19.22 bcfd in August. (Reporting By Jessica Resnick-Ault Editing by Marguerita Choy)
