That won’t fly for a second. France’s Total and Schlumberger will fill that void in a NY city taxicab minute. Not to mention assorted state-owned oil companies and tech and support firms.
Anyone that does business with Russia under the present management is a fool.
Last time it took two or three years to make an impact on chip and software exports to the east. Then Ron and Yasu sat down and worked something out. After that the Koreans and Singapore fell in line. This may be a simpler program to implement as there are far fewer countries and far fewer companies producing really advanced oil recovery technology that Russia will need. Despite the historic confluence of interest it's possible that M. Sarkosi may be amenable to a deal. It will cost us but it may be possible to work something out.
All of this would have to be worked out as part of G7 strategy (yes, G7) to economically isolate Russia.
Disclosure, I hold shares of both BHI and SLB.
