Statoil together with operator Repsol Sinopec and partner Petrobras has completed the Gavea A1 well in the ultra-deep pre-salt block BM-C-33 in the Campos basin in Brazil.
The well encountered a hydrocarbon column of 175 m in a good-quality reservoir of silicified carbonates of the Macabu formation.
The well reached a total depth (TD) of 6230 m and was successfully tested producing around 16 million standard ft3 of gas and 4000 bpd of oil (32/64 in. choke).
This is the fourth appraisal well in the licence, which comprises the Seat, Gavea and Pão de Açucar (PdA) discoveries. In 2013-2015 the consortium drilled and tested the Seat-2, PdA-A1 and PdA-A2 appraisal wells.
With Gavea A1 the consortium has finalised the appraisal activities in BM-C-33 and will now evaluate the sub-surface data and assess lean and cost-effective development concepts.
Repsol Sinopec Brasil (35%) is operator of BM-C-33 with Statoil (35%) and Petrobras (30%) as partners.
As announced in December 2015, Statoil will take over operatorship of the licence. This is expected to happen in the third quarter of 2016, subject to the approval from Brazilian authorities (ANP).
