U.S. crude oil production rose 231,000 barrels per day (bbl/d), or 2%, to a record 10.674 million barrels per day (MMbbl/d) in June, the U.S. Energy Information Administration said in a pair of monthly reports on Aug. 31.

The agency also revised its estimate for May up by 1,000 bbl/d to 10.4 MMbbl/d.

U.S. crude production has been increasing, nearing top producers Russia and Saudi Arabia. Saudi Arabia produced 10.5 MMbbl/d in August, according to a Reuters survey. Russian output was seen at 11.2 MMbbl/d in July, and was expected to hold that level in August.

U.S. output has been closely watched by crude oil markets, which have contended with concerns about oversupply as oil production ramps up and trade tensions between the United States and China weigh on global demand forecasts.

The gains reflected growing production onland in Texas, where output climbed 165,000 bbl/d, or 3.9%, to 4.4 MMbbl/d. Output also rose in the Gulf of Mexico, climbing 10.3%, or 154,000 bbl/d to 1.7 MMbbl/d.

Crude and refined products exports rose from a month earlier. Crude oil exports rose nearly 200,000 bbl/d in the month, hitting a fresh record of 2.2 MMbbl/d, more than twice the level seen in June a year ago.

Gasoline demand in June increased 0.3%, or 32,000 bbl/d, from a year earlier to 9.8 MMbbl/d, compared with a 0.4% decline in May. Distillate demand fell 0.4%, or 15,000 bbl/d to 4 MMbbl/d, compared with a 7.7% rise in May, according to the Petroleum Supply Monthly report.

U.S. natural gas production in the lower 48 states rose to an all-time high of 90.8 billion cubic feet per day (Bcf/d) in June, up from the prior record of 89.9 Bcf/d in May, according to EIA's 914 production report.

Output in Texas, the country's largest gas producer, increased 1.5% in June to 23.9 Bcf/d.

In Pennsylvania, the second biggest gas producing state, production rose 2.2% to 16.5 Bcf/d in June. The United States has been the world's biggest producer of gas since 2009, ahead of Russia.
