1 Huge Reason : Weatherford shut down manufacturing in US & moved it to China .
Cheap Labor ... $.50 cents an hr.
US should only do business with Companies that doesn't move manufacturing overseas & heavily tax any imports of products SLB manufactured overseas . Also award contracts to their competitors still with manufacturing in US.
Of course we also know 1 huge trick SLB has been playing for decades ::: Import more foreigners to replace more US citizens still working for SLB here. Then they tell our Government they still employ a lot of people living in US.
Deception & Lies to get way ahead .
