Houston-based oilfield services company Baker Hughes Inc. reported that the number of rigs exploring for oil and natural gas in the U.S. dropped by 12 this week to 464, a record low amid continuing price woes in the energy industry.
A year ago, 1,048 rigs were active. At its peak in 1981, the U.S. rig count reached 4,530. It previously bottomed out at 488 in 1999.
