There is a lot of oil to be had up there, just not 400 billion barrels. It’s a very tight formation from what I’ve read.
It is 400 MMMBO in place. Being an unconventional reservoir, the recovery factor is 5 to 10%, so that would be 20 to 40 MMMBO recoverable. A typical conventional oil field has a recovery that varies from 30 to 70%.
