"The fall of the House of Saud seems the most far-fetched of the six possibilities, and it's the one that generates that $262 a barrel. More realistic -- and therefore more chilling -- would be the scenario where Iran declares an oil embargo a la OPEC in 1973, which Browder thinks could cause oil to double to $131 a barrel. Other outcomes include an embargo by Venezuelan strongman Hugo Chavez ($111 a barrel), civil war in Nigeria ($98 a barrel), unrest and violence in Algeria ($79 a barrel) and major attacks on infrastructure by the insurgency in Iraq ($88 a barrel)."
