HOUSTON — The number of rigs exploring for oil and natural gas in the U.S. dropped by nine this week to 406, another all-time low amid depressed energy prices.
A year ago, 888 rigs were active.
Houston oilfield services company Baker Hughes Inc. said Friday 328 rigs sought oil and 86 explored for natural gas. One was listed as miscellaneous.
Among major oil- and gas-producing states, Texas declined by seven rigs; Louisiana, three; and North Dakota, Oklahoma and Wyoming, one each.
New Mexico gained two rigs and California one.
Alaska, Arkansas, Colorado, Kansas, Ohio, Pennsylvania, Utah and West Virginia were all unchanged.
The previous low of 488 set in 1999 was eclipsed March 11, and has continued to slide.
