The number of rigs actively exploring for oil and natural gas in the U.S. was unchanged this week from a week ago, at 1,830.
Houston-based Baker Hughes Inc. reported Friday that 954 rigs were exploring for oil and 866 for gas. Ten were listed as miscellaneous. A year ago, the count was 1,518.
Of the major oil- and gas-producing states, California gained four rigs while Pennsylvania and Texas picked up two apiece. Arkansas, North Dakota and West Virginia each gained one.
Oklahoma lost eight rigs, Louisiana lost four and Alaska lost one. Colorado, New Mexico and Wyoming were unchanged.
The rig count peaked at 4,530 in 1981, the height of the oil boom. The record low of 488 was in 1999.
