The offshore Gavea A1 appraisal well has been classed a success by partners, Repsol Sinopec, Statoil and Petrobras, after producing high flows.
An initial flow test on a 32/64” choke, has shown production rates to be in the region of 16 million standard cubic feet (scf) of gas and 4,000 barrels of oil per day.
Success At Offshore Pre-Salt Well
Located in block BM-C-33 offshore Brazil, Gavea A1 has been drilled in the ultra-deep pre-salt Campos Basin.
Ultra deepwater drillship, the Ocean Rig Mylos, completed the well, drilling the well to a total depth (TD) of 20,440 feet (6,230m); encountering a hydrocarbon column of 574 feet (175m) in a good-quality reservoir of silicified carbonates of the Macabu formation.
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).Last updated on 07:04PM - 19/04/16
