Repsol Sinopec同挪威和巴西國家石油公司合作共同建設完成了Gavea A1 超深井，該井位于巴西海上Campos 盆地的BM-C-33區塊，屬鹽下層系。
該井在油藏條件較好的Macabu硅化碳酸鹽儲層鉆遇到厚度為175m的碳氫化合物。
挪威國家石油公司在一份聲明中表示該井總深度達6230米，試采結果良好，使用32/64的油嘴，產氣量可達1600萬立方米，日產油可達4000桶。
該井為公司所鉆的第四口具有許可協議的評價井，前三口分別為在2013-2015年進行鉆進和測試的Seat-2, PdA-A1 and PdA-A2 評價井。
Gavea A1評價井的完成標志著該公司已經完成在BM-C-33區塊的評價任務，現正著手于地下數據和高效開發的評估工作。
Repsol Sinopec Brasil (份額占35%)是BM-C-33的運營商，挪威國家石油公司(份額占35%)和巴西國家石油公司(份額占30%)是其合作伙伴。
挪威國家石油公司計劃將在第三季度接管許可經營權。

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 P?o de A?ucar (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.
