Petrobras Discovers Hydrocarbons 201 km Offshore in Pre-Salt Campos Basin Well
Petrobras confirmed hydrocarbons in the pre-salt 1-BRSA-1404DC-RJS well in the SC-AP4 sector of the Campos Basin C-M-477 block, 201 km off Rio de Janeiro in ~3,000 m water depth. Petrobras, with a 70% stake alongside BP’s 30%, dispatched fluid samples for lab analysis to guide reservoir appraisal and development planning.
1. Discovery Details
Petrobras confirmed the presence of hydrocarbons in the 1-BRSA-1404DC-RJS exploratory well within the pre-salt layer of the Campos Basin. The well, located in the SC-AP4 sector of block C-M-477, lies roughly 201 kilometers off Rio de Janeiro in water depths near 3,000 meters.
2. Joint Venture Structure
Petrobras holds a 70% working interest in the C-M-477 block, with BP retaining the remaining 30%. The block was awarded through Brazil’s 16th ANP licensing round and operates under a concession regime.
3. Appraisal and Development Plans
Fluid and gas shows detected via electrical logs prompted the dispatch of fluid samples for laboratory analysis. These tests will determine reservoir quality and guide the design of upcoming appraisal drilling and development planning.
4. Strategic Significance
This discovery underlines Petrobras’ focus on replenishing reserves through frontier exploration in pre-salt territories, leveraging advanced seismic and drilling technologies. Success in the Campos Basin helps support long-term production growth while balancing upstream investment and energy transition objectives.
