The facts
Morpho lies in block FZA-M-59, in a water depth of 2,886 metres. The three reported discoveries concern intervals within one well. [1][2]
Petrobras said continued evaluation after discoveries announced in August and early October identified the additional oil-bearing interval. [1][2]
The company said remaining well-closure operations would be completed before the drilling rig moves to the Potiguar Basin, off Rio Grande do Norte, to drill the Mãe de Ouro prospect. [1][2]
Petrobras describes the exploration as part of its long-term strategy to replenish oil and gas reserves. That strategy is distinct from a quantified reserve estimate for this discovery. [1]
Still unconfirmed
- The commercial recoverable volume, final development decision, production timing and financial value were not established in the checked announcements.
