Brent had touched $US67.76 a barrel on Wednesday, its highest since November 16.

US West Texas Intermediate (WTI) crude futures were at $US58.29 per barrel, up 3 US cents, or 0.1 per cent, from their last settlement.

WTI hit a high of $US58.48 a barrel on Wednesday, the highest since November 13.

“OPEC continues to cut output amid ongoing supply issues, while the situation in Venezuela remains bleak,” ANZ Bank said in a research note.

Two storage tanks exploded at a heavy-crude upgrading project in eastern Venezuela on Wednesday, according to an oil industry source and a politician, while the country’s main oil terminal resumed shipments after a prolonged blackout.

US crude stocks also fell last week as refineries hiked output, the Energy Information Administration said.

Crude inventories fell by 3.9 million barrels in the last week, compared with analysts’ expectations for an increase of 2.7 million barrels.
