I think the LNG stake is the most likely candidate that swayed the deal in favor of Total. 30% versus, well, what? Do we know any stake in the plant (or train) was on the table?
This actually speaks highly of IOC's belief in finding more significant fields in PRL 15, with a significant stake in the plant, they get to earn big bucks on these (as well as on EA gas).
Let's not forget that this is where most of the money is, even if it takes a lot longer. Gas in the ground sells for what $1/mcf. LNG sells for close to $20/mcf these days. Remains to be seen whether that still holds at the end of the decade, but marginal costs are not likely to decline..
But does it, I find the possibility of putting up a CSP and pumping the dry gas to Exxon until Total's plant is up and running rather interesting.
