For each of the last two containment caps, as they were installed there was a boast of ability to trap more oil & gas for recovery into tankers.
Instead, the daily reports were about how much oil & gas was captured and how much was burned off. The numbers were always equal, that I have seen.
Has any oil actually been loaded onto tankers/barges?
Yes. The Enterprise Inspiration was capturing oil from the cap and transferring it to a tanker ship that carried to the depot. I want to say the first load was 300,000 barrels. They were burning off the natural gas. I posted an update a few weeks ago about it. The Helix and the other ship that were connected to the BOP directly were just burning everything off.
