The number of rigs actively exploring for oil and natural gas in the U.S. increased by 28 this week to 1,800.
Houston-based Baker Hughes Inc. reported that 913 rigs were exploring for oil and 878 for gas. Nine were listed as miscellaneous. A year ago, the count was 1,482.
The report was issued Thursday, a day early because of the Good Friday holiday.
Of the major oil- and gas-producing states, Texas gained 22 rigs and Oklahoma picked up four. Pennsylvania added two, and Wyoming and North Dakota gained one apiece.
Alaska, Arkansas, Louisiana and New Mexico lost one rig each. California, Colorado and West Virginia 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.
