Eni confirms 650 million barrels of oil with Agogo’s first appraisal well

Italy’s Eni has successfully drilled Agogo-2, the first appraisal well of the Agogo discovery in Block 15/06, offshore Angola.

The well results confirm the 650 million barrels of oil in place at the Agogo field and indicate further upside in its northern sector that will be assessed with new appraisal wells, Eni said in a statement on Thursday.

Agogo-2 has been drilled by the Poseidon drillship, 3 kilometers north-west of the Agogo-1 discovery well, approximately 180 kilometers from the coast and 23 kilometers from the N’Goma West Hub floating production and storage facility (FPSO). The well was drilled in a water depth of 1,700 meters and reached a total depth of 3,949 meters.

Eni said that Agogo-2 encountered 58 meters net of light oil (31° API), in sandstones of Miocene and Oligocene age with excellent petro-physical characteristics. The result confirms the extension of the Agogo reservoir to the north of the discovery well and below the salt diapirs. The well has been planned and drilled as a highly deviated one, to reach the sequences below the salt diapirs and prove the existence of reservoir and oil charge also in this sector of the Agogo megastructure. Data acquired in Agogo-2 indicate a production capacity in excess of 15.000 barrels of oil per day.

The Block 15/06 JV is composed by Eni, the operator of the asset with a 36.8421% stake, Sonangol P&P which has 36.8421% and SSI Fifteen Limited who holds the remaining 26.3158%.

Eni plans to start first production from Agogo before the end of 2019 with a subsea tie back to the N’Goma FPSO. Meanwhile, Eni will continue the appraisal campaign to assess the discovery’s full potential and size its development.

The Poseidon drillship was previously owned by Ocean Rig until the driller was acquired by Transocean in December 2018. The drillship started working for Eni in Angola in November last year following a drilling campaign in Namibia where it had drilled for Chariot and Tullow. Eni hired the Poseidon for a firm four-well program.
