Eni appraisal increases Agogo resource estimates

Oilfield Technology,

Eni has drilled Agogo-3, the second appraisal well of Agogo discovery in Block 15/06, offshore Angola, increasing by about 40% the estimate of oil in place, which is now of 1 billion bbl with further upside to be tested in the Northern sector of the field.

Agogo-3 has been drilled by the Libongos drillship 1.5 km North-West of the Agogo-2 and 4.5 km North-West of Agogo-1 wells. Agogo field is located approximately 180 km from the coast and 23 km from the West Hub (N’Goma FPSO). This appraisal well is located in a water depth of 1700 m and reached a total measured depth of 4321 m.

Agogo-3 encountered up to 120 m of net pay of light oil (31°API) in sandstones of Miocene and Oligocene age with excellent petrophysical properties. An intense data acquisition has been carried out in the well; the data confirm the communication with Agogo-2 reservoirs and the further extension of the Agogo discovery to the North. Agogo 3 has been planned and drilled as a highly deviated well to reach the sequences below the thick blanket of salt, leveraging on Eni’s advanced proprietary seismic imaging technologies and confirmed the existence of oil charged and connected reservoir also in this subsalt sector of Agogo megastructure. The data acquired indicate a production capacity in excess of 15 000 bpd.

The Block 15/06 joint venture (Eni, operator, 36.8421%; Sonangol P&P, 36.8421%; SSI Fifteen Limited, 26.3158%) announced in January 2020 the production start-up of Agogo field with a subsea tie back to N’Goma FPSO of Agogo 1, only 9 months after the discovery. Eni and JV partners have already started the studies to exploit the full potential of the field through a third production hub, targeting an FID in 2021.
