Brent crude rose 75 cents, or 1.1 percent, to $69.63 a barrel at 1155 GMT. US West Texas Intermediate (WTI) crude was up 67 cents, or one percent, to $66.36 a barrel, Reuters reported.
Both contracts hit the highest level since mid-March in intra-day trade.
"A return to $70 oil is edging closer to becoming reality," said Stephen Brennock of oil broker PVM.
"The jump in oil prices came amid expectations of strong demand as western economies reopen. Indeed, anticipation of a pick-up in fuel and energy usage in the United States and Europe over the summer months is running high," he said.
Crude prices were also supported by a large fall in US inventories.
The American Petroleum Institute (API) industry group reported crude stockpiles fell by 7.7 million barrels in the week ended April 30, according to two market sources. That was more than triple the drawdown expected by analysts polled by Reuters. Gasoline stockpiles fell by 5.3 million barrels.
The rise in oil prices to nearly two-month highs has been supported by COVID-19 vaccine rollouts in Europe and the United States where more than 40 percent of US adults have received a vaccine.
Eurozone business activity accelerated last month as the bloc's dominant services industry shrugged off renewed lockdowns and returned to growth.
"The partial lifting of mobility restrictions, the expectation that tourism will return in the near future, and the lure of the psychologically important $70 mark are all likely to have contributed to the price rise," Commerzbank analyst Eugen Weinberg said.
This has offset a drop in fuel demand in India, the world's third-largest oil consumer, which is battling a surge in COVID-19 infections.
"However, if we were to eventually see a national lockdown imposed, this would likely hit sentiment," ING Economics analysts said of the situation in India.
