据普氏能源资讯2019年5月9日休斯敦报道，标准普尔全球普氏能源资讯分析公司周四公布的统计数据显示，尽管美国国内油价继续稳定在每桶60美元以上，然而，在截至5月8日的一周内，美国在用石油和天然气钻机总数环比仍下降了13部至1071部，从而恢复了6个月来的下降趋势。
在最近几周里，由于上游运营商——其中许多上游运营商在今年年初就制定了大规模的钻井活动计划——在完成一个项目或准备钻探新油井以后释放一部钻机，美国在用钻机数的下降出现了上下波动。上周，美国在用钻机数增加了18部，在4月份的大部分时间里每周都在下滑之后，目前已降至1084部。
美国在用钻机数在2018年11月中旬达到1233部的峰值，此后逐渐减少。今年2月中旬，这个数字跌破了1100部大关，自那以来一直保持在1100部左右的水平。
统计数据显示，本周美国在用石油钻机数减少了5部至852部，而天然气钻机数减少了6部至218部。此外，油气混合钻机数减少了2部。

US oil and gas rig count falls 13 US oil and gas rigs fell 13 to 1,071 the week ended May 8, S&P Global Platts Analytics said Thursday, resuming what has generally been a six-month downward trend despite domestic oil prices continuing firmly above $60/b.
The rig count drop has fluctuated up and down in recent weeks as upstream operators - many of whom have heavy early-2019 activity programs planned for the year - released a rig after finishing a program or prepared to drill new wells. Last week the rig count gained 18, landing at 1,084 after spending much of April slipping each week.
The US rig count peaked in mid-November 2018 at 1,233 and has gradually decreased since then. It dropped below 1,100 in mid-February and since then has generally stayed around the high 1,100s.
This week's rig count decrease was for both oil and gas. Oil-directed rigs were down by five to 852, while rigs chasing gas fell by six to 218.
In addition, a two-rig decline was posted for rigs not specified for either oil or gas.
