3)....and face unrest in Nigeria,Angola ,Guinea and consequent disruption of ExxonMobil plants. Africa has become "interesting" since they found exploitable oil fields there
Funny how you missed the fact that those are primarily European and Chinese supplier
I should have added some clarifications about oil industry.
Worldwide oil exploration, extraction ,transportation, refining, distribution is dominated by 8-9 Oil Majors of wich ExxonMobil is the biggest. Developments of oil fields in remote areas are usually made by joint ventures including local oil cos' (if there are) plus 2-3 majors. So while industrial nations tend to be supplied by the nearest oil producing areas, it has no implications about the nationality of the Majors doing the job.
I add another irritating ranking, of the world biggest publicy traded oil companies by market value, according Yahoo Finance:
1) ExxonMobil ((U.S.) 372.5 B
2) British Petroleum (Britain) 244.1 B
3) Petrochina (China) 154.6 B
4) Total (France) 152.0 B
5) Royal Dutch (Netherlands) 131.5 B
6) Chevron (U.S.) 126.8 B
7) Eni (Italy) 109.3 B
8) ConocoPhillips (U.S.) 89.4 b
Aggregate data:
1) Europe 636.9
2) U.S. 588.7 B
3) China 154.6 B
