Kopernicus,
BLK have a 70% share of project so their net cash flow on your margin is $10.5B
even if you discount the price of oil to $60 a barrell and a cost of $45 a barrell to produce, that's a net cash flow of $3.486B to BLK
obviously a lot of water needs to pass under the bridge but there's big incentive for BLK to develop the asset
