I don't think you are correct on Polvo.
This from page 7--
"In early July, HRT entered into a purchase and sale agreement with Maersk Energia Ltda (“Maersk”) for the acquisition
of 40% in the exploration, development and production rights in the area of the Polvo Field, located in the Campos
Sedimentary Basin.
The conclusion of the purchase and sale transaction between HRT and Maersk is subject to certain conditions, among
them, ANP’s definite approval. Once the transaction is approved, HRT will become the holder of a 100% WI in the Polvo
Field."
Looks like the purchase has not been completed.
