The Brazilian state player confirmed the extension of the pre-salt discovery following the latest find at the Apollonia probe.
The appraisal well in Block BM-S-24, which has not yet finished drilling, threw up a 313-metre hydrocarbons column, Petrobras said on Wednesday.
Apart from a gas cap and condensates, an 87-metre oil column was struck in rocks of good porosity and permeability. The latest find was made below 5166 metres.
Petrobras is using the Queiroz Galvao Oil & Gas semi-submersible rig Gold Star to drill the well in 2183 metres of water some 296 kilometres off the coast of Rio de Janeiro.
The well, which is 8 kilometres south-west of the original discovery well at Jupiter, was spudded on 9 June and is expected to take four months to reach total depth of 5700 metres.
It aims to give Petrobras a better understanding of the oil-water contact and carbon dioxide content within the reservoir.
The Gold Star will then be moved to spud the Bracuhy NE appraisal well, also on BM-S-24, in the fourth quarter.
Petrobras also plans a drillstem test at Bracuhy NE, in a bid to help define the development project and to de-risk the deployment of additional production units in the area.
Petrobras and project partner Galp Energia plan to install a floating production, storage and offloading vessel at Jupiter in 2019, though more FPSOs may be allocated in the future.
Discovered in 2008, Jupiter is a massive carbonate reservoir composed of oil, condensates and a high concentration of CO2. Two appraisal wells were drilled a few years ago in BM-S-24.
