Petrobras has confirmed a new oil discovery in the pre-salt layer of Campos Basin, reinforcing its reserve replacement strategy in mature offshore areas in Brazil.
Oil Discovery at Marlim Sul Field
First, the discovery occurred at exploratory well 3-BRSA-1397-RJS, located in the Marlim Sul field, approximately 113 kilometers off the coast of Campos dos Goytacazes. Drilling was performed at a water depth of 1,178 meters.
According to the company, excellent quality oil was identified, increasing the technical and economic interest of the reservoir. This type of crude is typically associated with greater efficiencies in production and processing.
Confirmation Through Technical Analysis
Furthermore, the presence of hydrocarbons was confirmed through electric logs, gas indicators, and fluid sampling. These techniques enable precise validation of oil presence in deep geological formations.
Likewise, the collected samples will be sent to the laboratory to characterize reservoir and fluid properties. This process will be key to determining the productive potential of the area.
Reservoir Potential Assessment
At this stage, Petrobras will advance with more detailed studies to define the development viability of the reservoir. The assessment includes analysis of permeability, pressure, and crude composition.
Additionally, this data will be fundamental for designing future drilling and development campaigns in the pre-salt zone.
Reserve Replacement Strategy
For its part, the company maintains as its primary objective the reinforcement of its reserves in mature basins such as Campos. This approach seeks to ensure operational sustainability in an energy transition context.
The Marlim Sul field, originally discovered in 1987, remains a key asset for Petrobras, which currently holds 100% participation and operates the area.
Finally, the company emphasized that drilling was performed under strict safety standards, with respect for the environment and the people involved in offshore operations.
