据普氏能源资讯2019年5月16日休斯顿报道，根据标准普尔全球普氏能源资讯分析公司的最新统计数据，美国在用石油和天然气钻机总数在周四结束的当周减少了6部至1065部，延续了过去6个月的稳步下降趋势，期间偶尔会出现曲折。
统计数据显示，本周美国在用石油钻机数大幅减少了14部至838部，而本周在用天然气钻机数增加了6部至224部。此外，未指定用于石油或天然气的钻机数增加了2部。
去年同期，美国在用钻机总数为1117部。上周在用油气钻机总数平均为1071部，而此前一周为1084部。
2018年11月中旬，美国国内在用钻机总数达到了1223部，创下了近期新高，此后逐渐减少，不过也出现了一些周期性的显著增长。然而，总体而言，趋势是小幅下滑。
