The oil driller Baker Hughes reported that the number of active U.S. rigs declined by 4 rigs to 631 last week, the lowest weekly level since August 06, 2010. It was the 28th consecutive weekly fall.
Combined oil and gas rigs fell by 2 to 857. It was the lowest level since January 17, 2003.
Oil production in the U.S. continues to rise despite the decline in oil rigs.
The U.S. Energy Information Administration forecasts that U.S. crude-oil production would begin to fall from June until February 2016.
