Abu Dhabi said it's ready to increase oil output in line with guidelines set by OPEC and allied producers, echoing comments by Saudi Arabia that it will boost supply to meet demand.

ADNOC "has the ability to increase oil production by several hundred thousand barrels of oil per day, should this be required to help alleviate any potential supply shortage in the market," it said Tuesday in an emailed statement.

Adnoc, as the company is known, can pump as much as 3.3 million barrels of crude a day and will increase output capacity to 3.5 million barrels daily by the end of the year.

Abu Dhabi has most of the oil deposits in the United Arab Emirates and is the capital of the Middle Eastern crude producer. The U.A.E. pumped 2.89 million barrels of crude a day in June, 20,000 barrels a day more than in May, according to a Bloomberg survey. Crude and condensate exports rose to a nine-month high in June on demand from Japan and China.

Saudi Arabia and the U.A.E. are pledging to add barrels amid calls by U.S. President Donald Trump for more oil from the Organization of Petroleum Exporting Countries. Trump, in an interview on Fox News on Sunday, called on OPEC to add 2 million barrels of crude to the market.

Oil prices have gained more than 3 percent since OPEC and allies agreed on June 22 to raise output to meet production caps set in 2016. Some OPEC members, including Venezuela and Libya, haven't been pumping up to their limits, contributing to gains in prices over the past week. Brent crude increased 0.6 percent to $77.73 a barrel at 8:36 a.m. in London.
