Oil up as OPEC cuts output, dollar dives

By Devika Krishna Kumar NEW YORK (Reuters) - Oil prices rose on Tuesday on a weak U.S. dollar and news that the world's top producers cut production this month more than forecasters had expected. "This is very high, a good number," an OPEC source said of the January compliance estimate. Prices pared gains slightly after Iraqi Prime Minister Haider al-Abadi said oil prices will not reach "levels desired" by Iraq before the end of 2018 or 2019.
