Interesting. So Tupi represents something more real than Jack. However it still

represents globally, at its peak ... less than half a percent of the world oil production

which is the key metric.

If you were to reverse the marketing spin effect, that suggests you would need to hear claims of reserves in the +20Gb range to relate to a find which could hit the 1Mbpd level needed to make a change to the price of fish?

Plus "800 Km long by 200Km wide" suggests a fragmented field, pushing up costs.

Tupi does not cover that area entirely, it is just a small part of it and most likely a single reservoir.

That's why there's so much excitement about it, this could be just the first field of a larger complex.
