Brazil’s Petrobras will invest $9 billion in development activities on the Buzios field through 2023, increasing its upstream focus on core assets in the Santos basin pre-salt province, writes Gareth Chetwynd.

The Buzios project will absorb major investments in drilling and well completion to serve the first five floating production, storage and offloading vessels, four of which are already installed in the field, according to Petrobras production development and technology director Rudimar Lorenzatto.
