I am a Brit by birth an still own a home in the UK an live there several months each year, so I guess its only reasonable thet I know British culture ;-)
Now what is that truley Brit sayin, 'The boot is on the other foot' or somethin similar. WE, that is Sibir own the mineral extraction rights to Salym, Shell participation in thet extraction process is dependent on them providin the extraction costs...They don't payup an they are outta the scene! Sibir cant lose - every oil company is lookin to extract more than last year in order to stay in the peckin order, any one of which would step into Shells shoes without hesitation. Hope thet has put your mind at rest?
