Blackjack, there is NO WAY STO have simply "invested" in ESG. They want all that gas. To fully capitalise on GLNG, they need to throw as much GAS as quickly as possible at the project.
I predict SANTOS will have a go at ESG with one or more of their cashed up partners...
After ESG is re-rated after the reserves upgrade, they have to bring some serious money to the table ;)
