Petróleo Brasileiro SA (Petrobras) will assess dimensions and commerciality of a discovery in Aram block after having successfully completed a drill-stem test (DST) of exploration well 1-BRSA-1381-SPS (Curaçao). The discovery lies 240 km from the city of Santos, State of São Paulo, in the southwest portion of Santos basin presalt at a water depth of 1,905 m.
Hydrocarbons had been previously identified in the well through wireline logging and fluid samples (OGJ Online Nov. 22, 2021). The DST investigated a thick interval of petroleum-bearing pre-salt carbonates, whose productivity was evaluated by dynamic production data. Oil samples were collected during the DST to be further characterized by laboratory analyses.
Petrobras is operator of Aram block (80%) with partner China National Petroleum Corp. (CNPC, 20%).
