Oil prices added to overnight gains on Tuesday, buoyed as more US states eased lockdowns and the European Union sought to attract more travellers, which would help offset weakened fuel demand in India as Covid-19 cases soar.
Brent crude futures rose 14 cents, or 0.2%, to $67.70 a barrel at 0150 GMT, after climbing 1.2% on Monday.
US West Texas Intermediate (WTI) crude futures also rose 14 cents, or 0.2%, to $64.63 a barrel, after gaining 1.4% on Monday.
Prices are being supported by the prospect of a pick-up in fuel demand in the United States and Europe, as New York state, New Jersey and Connecticut were set to ease pandemic curbs and the European Union planned to open up to more foreign visitors who have been vaccinated, analysts said.
"This should boost holiday travel to coastal regions, as well as increase mobility in major cities," ANZ Research analysts said in a note.
For further signs of rising US oil demand, traders will be watching out for reports on crude and product stockpiles from the American Petroleum Institute on Tuesday and the US Energy Information Administration on Wednesday.
Five analysts polled by Reuters estimated on average that US crude inventories fell 2.2 million barrels in the week to April 30. Oil inventories rose in the previous two weeks.
The rate of refinery utilization was expected to have increased by 0.5 percentage points last week, from 85.4% of total capacity in the week ended April 23, according to the poll.
