Doing this analysis is definitely given me a slightly awed sense of respect for the oil industry. They deliver dozens of new projects a year and each of those is a massive multi-billion dollar engineering project in enormously challenging conditions.

Bravo!

Oh yeah. Kashagan (in the Kazakhstan part of the Caspian sea) is going to be a textbook example for years to come of the complexity of these projects (not sure in which year you put it in, but 2007 is possibly it)

  • extraordinarily high field pressure
  • very high sulfur content
  • located in shallow waters that are alternatively frozen, liquid (10m or so) or mud
  • the nearest town is 400 km away, and the nearest international airport 1,500 km away; winter lasts 10 months and summer is worse (mosquitoes and stifling heat)
  • you need to cross at least 2 countries to get the oil to any market
  • the sponsors include Shell, Exxon, ConocoPhillips and Total (plus others) as minority non-operating shareholders
  • China, Iran, Russia and the USA (well, the West) want the oil to come to (or via) them.

Should be fun to watch.
Yes, and then there's the political environment in Kazakhstan itself. I have Kashagan for 2008 but the risks are considerable as you note. It is enormous, however.
Re: "the nearest town is 400 km away..."

It's not for nothing that the whole region is sometimes called pipelanistan....
