US rig count up 20 this week

HOUSTON (AP) — The number of rigs exploring for oil and natural gas in the U.S. increased by 20 this week to 588.

A year ago, 757 rigs were active. Depressed energy prices have curtailed oil and gas exploration, although the rig count has been rising.

Houston oilfield services company Baker Hughes Inc. said Friday that 471 rigs sought oil and 116 explored for natural gas this week.
