美国钻井人员运回9台抽油装置

Drillers put nine oil rigs back to work in U.S. fields last week, with the majority heading to the Permian Basin in West Texas, Baker Hughes said Friday. The increased drilling activity brings the fleet of U.S. oil rigs up to 450, up by 134 machines since the count fell to its annual low in late May.

Six oil rigs began work in the Permian Basin; two, in the Bakken Shale in North Dakota, and two others became active in the Eagle Ford Shale in South Texas and the Colorado’s DJ Basin. One oil rig went idle in an unnamed field, the Houston oil field services company said.
