Petrobras has announced a new hydrocarbon discovery in the pre-salt area of the Campos Basin offshore Brazil, following drilling activity in deepwater block C-M-477.
The discovery came from exploratory well 1-BRSA-1404DC-RJS in Sector SC-AP4. The well is located 201 km off the coast of Rio de Janeiro state in water depth of 2,984 m.
According to the company, the hydrocarbon-bearing interval was identified through electric logs, gas shows and fluid sampling. The collected samples will now be sent for laboratory analysis to define reservoir conditions and the characteristics of the fluids. That work will support the next stage of evaluating the block’s potential.
Block C-M-477 is operated by Petrobras, which holds a 70% working interest, while BP holds the remaining 30%. The block was awarded in the 16th Bidding Round conducted by Brazil’s National Agency for Petroleum, Natural Gas and Biofuels under the concession regime.
Petrobras said operations in C-M-477 form part of its strategy to renew oil and gas reserves through exploration in frontier areas carried out with partners. The company added that the approach is intended to help secure domestic energy supply during the energy transition.
The company has also moved to expand its hydrocarbon portfolio through recent rig deals with Valaris, Seadrill, Transocean, Ventura Offshore and Constellation.
