The Brent crude contract for August, which expired on Wednesday, ended the session up 37 cents, or 0.5% at $75.13 a barrel. The September contract rose 34 cents to settle at $74.62 a barrel. U.S. West Texas Intermediate crude (WTI) settled up 49 cents, or 0.7% at $73.47 a barrel.

Both benchmarks are just below highs last reached in 2018, and are set to record their seventh monthly gain in the past eight months. WTI rose more than 10% in June while Brent rose over 8%.

A Reuters poll showed that Brent was seen averaging $67.48 a barrel this year and WTI $64.54, both up from May's poll.

Inventories at Cushing, Oklahoma, the delivery point for WTI, slid to their lowest since March 2020, EIA data showed.

"With continued decline of Cushing crude oil inventories and an upcoming OPEC+ meeting tomorrow, I expect crude oil prices will rise as the market has been crying out for more supplies," said Andrew Lipow, president of Lipow Oil Associates in Houston.

The Organization of the Petroleum Exporting Countries and its allies, an alliance known as OPEC+, meet on Thursday. The group is expected to discuss extending its deal on cutting oil supply beyond April 2022.

An internal OPEC report seen by Reuters said the oil market would be in deficit in the short term but a glut was on the horizon once the OPEC+ supply cuts ended.

Hopes for a broad recovery received a boost from OPEC Secretary General Mohammad Barkindo, who said on Tuesday that demand is expected to rise by 6 million barrels per day (bpd) in 2021, with 5 million bpd of that coming in the second half of the year.

Goldman Sachs forecasts that demand will rise by a further 2.2 million bpd by the end of 2021, leaving a 5 million bpd supply shortfall.

"Our hypothesis is that we are going to have global travel-geddon to Europe, more demand for jet fuel that will drive us to $80 a barrel," said Jay Hatfield, portfolio manager for Infracap MLP ETF.

"But the real fly in the ointment for the bull case is the UK."

Britain recorded a further 26,068 cases of COVID-19 on Wednesday, the highest daily figure since Jan. 29 and sending the seven-day tally up 70% from the week before, official data showed.
