Producers were operating the fewest oil and natural gas drilling rigs on record in the United States at 339 on May 12, the lowest level in the Baker Hughes Company’s rig count data series that dates back to 1987. The number of active rigs began sharply decreasing in mid-March as crude oil prices fell: rigs have fallen by 56% (433 rigs) since March 17. Most of the decrease was in oil-focused geologic plays, but natural gas-focused plays also saw significant decreases.
