Petrobras CEO Says Morpho Well Drilling Ends in About 15 Days, With Volume Still Unknown

Petrobras chief executive Magda Chambriard said on Monday 17 that the state-controlled company is "extremely optimistic" about the oil discovery at the Morpho pioneer well in the Foz do Amazonas basin, on Brazil's Equatorial Margin, while confirming the size of the find is not yet known.

Drilling at Morpho should be completed in about 15 days, according to Chambriard. Only after that does the appraisal work begin: the next step is to delimit the discovery, measuring the reservoir's extent and its recoverable volume.

"There is oil, there is a discovery. We still do not know how much," Chambriard said, adding that Petrobras will keep investing and exploring, and that the future will show how much Amapa can offer.

The reserve-replacement arithmetic behind that language is explicit. Chambriard said 80% of Brazil's oil output now comes from the pre-salt, and that pre-salt production will peak around 2034 and 2035, after which reserves must be replaced if the country is to hold its place among the world's ten largest oil producers. Brazil currently ranks as the seventh largest global producer.

"From the peak onward, if we do not act, we will be oil importers as in the past," Chambriard said.

That framing puts an unquantified frontier well at the center of a national production trajectory. Chambriard called the find "extremely relevant" because it signals the continuity of Brazil, and of Petrobras, as a heavyweight producer on the world stage. She also argued that there is no future for an oil company without exploration.

The exploration program does not stop at one well. Petrobras is waiting on licences to drill three more wells in the same exploratory block, and five further areas are earmarked for new wells on the Equatorial Margin.

Chambriard spoke at a press conference in Oiapoque, in the state of Amapa, where she accompanied President Luiz Inacio Lula da Silva on a visit to the ODN II drillship. The vessel is responsible for the discovery announced on Friday 14.

For global crude balances, the sequencing matters more than the announcement. A pioneer well establishes the presence of hydrocarbons; the delimitation phase Chambriard described determines whether the reservoir supports commercial development at a scale relevant to replacing pre-salt barrels. Until that measurement exists, the discovery carries no volume that can be set against the 80% share of output Chambriard attributed to the pre-salt.

The licence queue is the near-term constraint on how fast that measurement arrives across the wider play. Three pending permits in the same block and five additional planned areas define the scope of the drilling effort Petrobras intends on the Equatorial Margin, and the pace of approvals sets when appraisal data from those locations becomes available.
