The rally received a boost from the International Energy Agency (IEA), which said the world's oil supply cushion "might be stretched to the limit" due to production losses.
Benchmark Brent crude oil rose $1.70, or more than 2.3 percent, to a high of $75.10 a barrel before easing back to trade around $74.30 by 1210 GMT. On Wednesday, Brent had slumped $5.46 or 6.9 percent.
U.S. light crude gained 50 cents to $70.88 a barrel, after falling 5 percent the previous session.
"Warnings from the IEA of a potential spare capacity crunch are helping the energy complex regain some ground following yesterdays bloodbath," said Stephen Brennock, analyst at London brokerage PVM Oil Associates.
An announcement by Libya's National Oil Corp that four oil export terminals were reopening, ending a standoff that had shut down most of Libya's oil output, was a key catalyst for the price fall on Wednesday, analysts said.
The reopening will allow the return of up to 850,000 barrels per day of high quality crude oil to international markets.
"Rising production from Middle East Gulf countries and Russia, welcome though it is, comes at the expense of the world's spare capacity cushion, which might be stretched to the limit," the Paris-based agency said in its monthly report.
"This vulnerability currently underpins oil prices and seems likely to continue doing so," the IEA added.
Prices also found support from a U.S. stocks report showing U.S. crude inventories fell by nearly 13 million barrels last week, the most in nearly two years, reducing overall crude stocks to their lowest point since February 2015.
The decline in U.S. inventories was partially due to a fall in stocks at the Cushing, Oklahoma delivery hub for U.S. crude futures, which dropped 2.1 million barrels.
Supply to the U.S. market has also been squeezed by the loss of some Canadian oil production.
