U.S. crude oil production unchanged last week

HOUSTON, Oct. 5 (Xinhua) -- U.S. crude oil production averaged 12 million barrels per day (b/d) during the week ending Sept. 30, unchanged from the previous week, the U.S. Energy Information Administration (EIA) said Wednesday.

The figure rose by 700,000 b/d from this time last year, according to the EIA.

More than 80 percent of the U.S. crude oil production growth comes from the country's Lower 48 states, which does not include production from Alaska and the Federal Offshore Gulf of Mexico, said the report.

The United States has become a major oil producer in the past years with the help of its shale oil production growth.
