The Houston company said in its weekly report Friday that 1,382 rigs were exploring for oil and 374 for gas. One was listed as miscellaneous. A year ago there were 1,763 active rigs.

Of the major oil- and gas-producing states, Alaska gained two rigs and Louisiana and Pennsylvania each gained one.

Texas declined by 10 rigs, West Virginia was down by four and Oklahoma by two. Arkansas, California, Colorado, Kansas, New Mexico, North Dakota, Ohio, Utah and Wyoming were unchanged.
