Houston's Baker Hughes said Friday that 564 rigs were seeking oil and 193 explored for natural gas. A year ago, with oil prices almost double the prices now, 1,929 rigs were active.
Among major oil- and gas-producing states, Louisiana and Oklahoma each lost four rigs, Colorado and Wyoming each declined by three, West Virginia lost two and Ohio declined by one.
Texas gained four rigs, Pennsylvania gained two and North Dakota increased by one.
Alaska, Arkansas, California, Kansas, New Mexico and Utah were unchanged.
The U.S. rig count peaked at 4,530 in 1981 and bottomed at 488 in 1999.
