Natural gas producers are scaling back output, boosting historically low prices, the Wall Street Journal reported.
Natural gas production took its biggest percentage drop in a year in February, the paper said in a front-page story published Friday.
Futures prices jumped 18% since April 19, reaching $2.253 per million British thermal units on May 2.
Analysts told the paper the production decline could be the beginning of a trend that would alleviate what has been an oversupply.
Truck and engine makers at the Mid-America Trucking Show in March said they see natural gas becoming a more widely used alternative to diesel fuel.
