UPDATE 2-U.S. crude oil production hit all-time record in November -EIA

(New throughout, adds details and background)

NEW YORK, Feb 28 (Reuters) - U.S. crude oil production shattered a 47-year output record in November and retreated slightly in December, the U.S. Energy Department said, as oil production from shale continued to upend global supply patterns.

Oil output rose to 10.057 million barrels per day (bpd) in November, a revision from earlier estimates, the EIA said. December production fell 108,000 bpd to 9.949 million bpd, the it said.

November's figure exceeded the 10.044 million barrels of daily production in November 1970. Output has surged in the last several years thanks to the shale boom, pushing the United States past Saudi Arabia among top producers. Only Russia now has greater daily oil output.

The new record likely won't last. The U.S. government forecasts that production will hit 11 million barrels per day later this year.

"Weve got a lot more oil to produce and we'll be through that 11 million barrel-per-day threshold much sooner than expected," said Phillip Streible, senior market strategist at RJO Futures in Chicago.

The gains are primarily due to rising production in key shale regions in Texas and North Dakota, which ramped up sharply at the beginning of the decade as new techniques involving hydraulic fracturing, or fracking, allowed drillers to extract vast quantities of crude from oil fields.

The increase in crude output has cut U.S. oil imports by a fifth over a decade, and boosted energy exports.

Soaring U.S. production kept a lid on oil prices this year, even though the Organization of the Petroleum Exporting Countries and Russia have reduced output.

In December, production pulled back after three consecutive increases, according to the EIA's report, known as the 914 production report.

The production decline was largely driven by Gulf of Mexico output, which dropped by 131,000 bpd in the month, even as production from shale in Texas continued to grow. Four Gulf of Mexico platforms were shuttered throughout the month in the wake of a fire.

U.S. natural gas production in the lower 48 states rose to a monthly all-time high of 87.1 billion cubic feet per day in December, from the prior record of 86.4 bcfd in November, according to the report.

The increase was driven by a 3.1 percent gain in Pennsylvania to a record high of 16.2 bcfd, and a 3.7 percent gain in Louisiana to 7.0 bcfd, highest since March 2013.

Output in Texas, the largest U.S. gas producer, eased 0.2 percent to 22.7 bcfd.
