Petrobras has discovered light oil and gas accumulation in the Tambuata prospect in Brazil’s offshore Espirto Santo basin. Well 4-GLF-31-ESS was drilled in 1.520 metres water depth in the Golfinho Concession (4-BRSA-1001-ESS).
The location is 74 km offshore and 7 km from the FPSO, floating production, storage and offloading vessel, Cidade de Vitória, on the eastern side of the Golfinho field.
“Drilling will continue to a planned depth of 6,100 metres in order to test deeper formations” said the Petrobras release.
“Cretaceous period, Santonian-age reservoirs have been identified at a depth between 4,530 and 4,670 metres with good conditions for production”.
The well is part of Petrobras’ Varredura project designed to boost the production of hydrocarbons in new finds close to existing offshore production systems.
It added its preliminary analysis of the well indicated excellent quality oil, condensate and natural gas.
The Golfinho field has previously been estimated to hold reserves at close to 300 million barrels of oil equivalent
