Oil prices rose to near three-week highs on Tuesday after OPEC said it was sticking to its agreement to cut production and hoped compliance with the deal would be even higher as it expects other producers join its efforts to curb a global glut.
OPEC Secretary General Mohammad Barkindo told an industry conference in London that January data showed conformity from participating OPEC nations with output curbs had been above 90 percent and oil inventories would decline further this year.
"All countries involved remain resolute in the determination to achieve a higher level of conformity," Barkindo said.
Benchmark Brent crude oil jumped 48 cents a barrel, or 0.9 percent, to $56.66 by 2:46 p.m. ET (1946 GMT). It hit a high of $57.31 earlier in the day.
U.S. light crude settled up 66 cents, or 1.2 percent, at $54.06, off a session peak of $54.68.
U.S. gasoline futures were the biggest drag on the energy complex, falling 1.5 percent to $1.4942 a gallon. That pushed gasoline crack spreads, an indicator of refining margins, to a fresh one-year low.
