Brent crude prices eased on Friday but hovered near $70 a barrel as production cuts by major oil producers constrained supply, with optimism about a recovery in demand for the resource in the second half of the year also lending support.
Front-month Brent is on track to post weekly gains for the eighth week after touching a 13-month high on Monday following attacks on Saudi Arabian oil facilities.
Sentiment was also buoyed by the decision of the Organization of Petroleum Exporting Countries (OPEC) and its allies, a group known as OPEC+, earlier this month to largely hold production cuts in April.
Investors have been pumping funds into commodities such as oil on expectations of a demand recovery in the second half of the year as the global economy grows while a wider rollout of vaccines against the Covid-19 pandemic allows more people to travel this summer.
"Assuming vaccination programmes are successful, we expect pent-up demand for gasoline to be released this summer during the U.S. and European driving season," FGE analysts said in a note.
RBC Capital analysts said the fundamentals for summer gasoline is the most bullish in nearly a decade.
"We think this will support the entire oil complex this summer and beyond."
The United States, world's largest oil consumer, saw a massive draw on U.S. gasoline stocks last week as the winter storm in Texas disrupted refining output.
OPEC said on Thursday a recovery in oil demand will be focused on the second half of the year.
