真实翻译：During the week ending May 12, the number of active drilling rigs in the US decreased by 17, indicating that oil and gas producers have started to shut down rigs in response to the recent sharp drop in the Henry Hub natural gas price. Of the 17 rigs, 16 were for natural gas and two were for oil, while one was a mixed rig. The Haynesville, Marcellus, and Permian shale regions saw the biggest declines in rig count, with five, three, and three rigs respectively. Eagle Ford and Cana Woodford both lost two rigs. Since the beginning of the year, the US rig count has fallen by 6% to 731. The latest onshore drilling model predicts that there will be 825 active drilling rigs in the US by the end of the year, a 13% increase from current levels.
