HOUSTON — The number of rigs exploring for oil and natural gas in the U.S. increased by 15 this week to 462.
A year ago, 876 rigs were active. Depressed energy prices have sharply curtailed oil and gas exploration.
Houston oilfield services company Baker Hughes Inc. said Friday that 371 rigs sought oil and 88 explored for natural gas this week. Three were listed as miscellaneous.
Among major oil- and gas-producing states, Texas gained 15, California was up by two and New Mexico gained one.
