Oil prices fell on Thursday, extending their previous session’s decline of more than 2%, as investors and traders look ahead to the OPEC+ meeting at the weekend, where producers are expected to consider another increase in production targets.

Brent crude dropped 27 cents, or 0.40%, to $67.33 a barrel by 01:14 GMT, while U.S. West Texas Intermediate crude fell 28 cents, or 0.44%, to $63.69 a barrel. Two sources familiar with the discussions told Reuters that eight members of the Organization of the Petroleum Exporting Countries (OPEC) and its allies—collectively known as OPEC+—will consider another production increase in October at the Sunday meeting as the group seeks to regain market share.

Phil Flynn, senior analyst at Price Futures Group, said the likelihood of an OPEC+ production increase had risen ahead of the meeting. Traders had been expecting no change from the group.

OPEC+ had already agreed to raise production targets by about 2.2 million barrels per day from April to September, in addition to increasing the United Arab Emirates’ quota by 300,000 barrels per day.

Over the past few months, despite accelerated production increases, oil prices in the Middle East have remained the strongest among regional prices globally. This has boosted the confidence of Saudi Arabia and other OPEC members in increasing production, according to a report by Haitong Securities.

Market participants are now awaiting U.S. government data on crude inventories, scheduled for release on Thursday but delayed by a day due to a U.S. holiday on Monday. U.S. crude oil inventories rose by 622,000 barrels in the week ending August 29, according to market sources citing data from the American Petroleum Institute (API) released on Wednesday. The API’s estimate of the U.S. crude inventory increase contradicted analysts’ expectations surveyed by Reuters, who had forecast, on average, a decline of 2 million barrels.
