Feb 22 (Reuters) - U.S. shale producer Marathon Oil Corp on Monday posted a smaller fourth-quarter loss compared with the third, helped by cost cuts and a recovery in commodity prices from pandemic lows on vaccine hopes.

Marathon, which postponed its earnings last week due to the harsh winter weather in Texas, said its adjusted loss was $98 million, or 12 cents per share, in the fourth quarter ended Dec. 31, compared with a loss of $219 million, or 28 cents per share, in the third quarter.
