The U.S. April crude contract , the new front-month future, was up 3 cents at $54.36 a barrel at 0028 GMT. On Tuesday, the March contract expired up 66 cents, or 1.2 percent, at $54.06, after peaking at $54.68, the highest since Jan. 3.
Brent crude was yet to trade after ending the previous session at $56.66 a barrel, up 48 cents or 0.9 percent. It earlier reached its highest since Feb. 2 at $57.31.
Mohammad Barkindo, OPEC secretary general, told an industry conference in London that January data showed conformity from member countries participating in the output cut had been above 90 percent. Oil inventories would decline further this year, he added.
Russia and the other outside producers have so far delivered a smaller percentage of cuts, but Barkindo said this would increase.
It was too early to say if the supply cut, which lasts for six months from Jan. 1, would need to be extended or deepened at the next OPEC meeting in May, he said.
