PetroRio SA is planning a 35 km tieback from Wahoo field in exploratory block C-M-101, offshore Brazil, to the Frade field FPSO, with the associated gas used for power generation on the platform.
Wahoo is in the presalt of Campos basin in 1,400 m of water. PetroRio plans to drill four producer wells in Wahoo in 2022 (OGJ Online, July 14, 2021).
Production at Wahoo, initially estimated at 10,000 b/d per well, could exceed 40,000 b/d, based on the results of the drill test carried out in an exploratory well. Wahoo could produce more than 140 million bbl and contains an estimated 126 million bbl recoverable reserves within a carbonate reservoir.
PetroRio is operator at Wahoo with 64.3% interest.
