Repsol Sinopec同挪威和巴西国家石油公司合作共同建设完成了Gavea A1 超深井，该井位于巴西海上Campos 盆地的BM-C-33区块，属盐下层系。
该井在油藏条件较好的Macabu硅化碳酸盐储层钻遇到厚度为175m的碳氢化合物。
挪威国家石油公司在一份声明中表示该井总深度达6230米，试采结果良好，使用32/64的油嘴，产气量可达1600万立方米，日产油可达4000桶。
该井为公司所钻的第四口具有许可协议的评价井，前三口分别为在2013-2015年进行钻进和测试的Seat-2, PdA-A1 and PdA-A2 评价井。
Gavea A1评价井的完成标志着该公司已经完成在BM-C-33区块的评价任务，现正着手于地下数据和高效开发的评估工作。
Repsol Sinopec Brasil (份额占35%)是BM-C-33的运营商，挪威国家石油公司(份额占35%)和巴西国家石油公司(份额占30%)是其合作伙伴。
挪威国家石油公司计划将在第三季度接管许可经营权。

RIO DE JANEIRO — Repsol Sinopec, with partners Statoil and Petrobras, has completed the Gavea A1 well in the ultra-deep pre-salt Block BM-C-33 in the Campos basin, offshore 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 6,230 m and was tested successfully, producing around 16 MMscf of gas and 4,000 bopd on a 32/64 in. choke, Statoil said in a statement.
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 sub-surface data and assess lean and cost-effective development concepts.
Repsol Sinopec Brasil (35%) is operator of BM-C-33. Statoil (35%) and Petrobras (30%) are partners.
Statoil is to take over operatorship of the license, a transition which is expected to take place in the third quarter.
