The Philadelphia Oil Service Index (OSXX) rose 2.6% to 128, led by a nearly 9% rise from Noble Corp (NE).

Weatherford (WFT) rose 4.5% to $11.33 after it managed to post a 5% increase in fourth-quarter net income despite losses throughout the sector.

Light, sweet crude for March delivery was last up $1.20 at $47.67 a barrel on the New York Mercantile Exchange, rebounding from an overnight low of $45.25 a barrel.
