Offshore staff

STAVANGER, Norway – Statoil together with operator Repsol Sinopec and partner Petrobras has completed the Gavea A1 well in the ultra-deepwater presalt block BM-C-33 in the Campos basin offshore Brazil.

The well encountered a hydrocarbon column of 175 m (574 ft) in a good-quality reservoir of silicified carbonates of the Macabu formation.

The well reached a total depth of 6,230 m (20,440 ft) and was successfully tested producing around 16 MMcf/d of gas and 4,000 b/d of oil through a 32/64-in. choke.

This is the fourth appraisal well in the license, 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 finalized the appraisal activities in BM-C-33 and will now evaluate the subsurface 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 license. This is expected to happen in 3Q 2016, subject to the approval from Brazilian authorities (ANP).
