U.S. crude oil settled higher on Friday to end the week in positive territory following a choppy trading session.
U.S. West Texas Intermediate (WTI) futures settled up 79 cents, or 1.7 percent, at $45.70 a barrel.
Brent futures were up 45 cents at $48.62 per barrel shortly by 2:36 p.m. EDT (1839 GMT). It had risen almost $1 at the session high, before turning negative prior to the rig count release.
Global rude markets seesawed around break-even much of Friday, jumping 2 percent in early trade on a boost from a Wall Street rally before slipping to near the day's lows.
Prices ticked back up after the latest weekly reading on the U.S. oil rig count from industry firm Baker Hughes showed a drop of 4 rigs, marking the fourth consecutive drop. A lower U.S. rig count is usually a bullish signal for oil as it suggests potentially lower production in the future.
