I don't see it effecting BAS, management has always worked well with the local government, infact in their last Presentation in May they state "Supportive local oil market & highly regarded by PT Pertamina and the regulator" also "Established and well-understood investment regime promoting foreign investment with stable fiscal terms"
Indonesia would be committing financial suicide by kicking out foreign investment, there would be sanctions put in place against them. They need outside experience/investment to bring these fields online plus they receive hefty tax payments from these foreign owned companies. Even Pertamina are struggling "No matter how you slice it, politically popular or no, economic nationalism has put Indonesia in a bit of a financial bind. Reviewing the H1 results, it certainly looks like Pertamina has taken on more than they can handle, but of course they are quite unlikely to get any foreign money without ceding control of production"
This is all a political stunt with a bit of hot air IMO.
