It resulted in an oil discovery with a size estimated between 200 and 250 million barrels of oil in place.
The Cuica-1 NFW has been drilled as a deviated well by the Libongos drillship in a water depth of 500 m, and reached a total vertical depth of 4100 m, encountering an 80 m total column of reservoir of light oil (38°API) in sandstones of Miocene age with good petrophysical properties. The discovery well is going to be sidetracked updip to be placed in an optimal position as a producer well. The result of the intensive data collection indicates an expected production capacity of around 10 000 bpd.
Cuica is the second significant oil discovery inside the existing Cabaça Development Area.
The well-head location, intentionally placed close to East Hub’s subsea network, will allow a fast-track tie-in of the exploration well and relevant production, while extending the Armada Olombendo FPSO production plateau. It is expected that production will start within six months after discovery.
Pursuant to the discoveries of Kalimba, Afoxé, Ndungu, Agidigbo, Agogo and appraisals achieved between 2018 and 2020, Cuica represents the first commercial discovery in Block 15/06 after the re-launch of the exploration campaign post-2020 COVID-19 pandemic and the drop in the oil price. A three-year extension of the exploration period of Block 15/06 has been recently granted until November 2023.
The Block 15/06 Joint Venture is composed of Eni (operator, 36.8421%), Sonangol P&P (36.8421%) and SSI Fifteen Limited (26.3158%).Besides the operated Block 15/06, with two producing hubs, and the development of a third hub on Agogo field, Eni currently operates in exploration phase Block 1/14 (offshore Lower Congo Basin), Blocks Cabinda Norte and Cabinda Centro (onshore) and will soon increase its operated areas with Block 28 in the offshore Namibe Basin. The current equity production is about 120 000 boe/d.
