Italy-based oil and gas firm Eni has completed drilling of Agogo-2, which is the first appraisal well of the Agogo discovery in Block 15/06, offshore Angola.

The results from Agogo-2 drilling have confirmed 650 million barrels of oil in place at the Agogo field and show further upside potential in the northern sector of the field that is expected to be assessed through new appraisal wells.

The well Agogo-2 drilled using the Poseidon drillship is located close to the north-west of the Agogo-1 discovery well, approximately 180km from the coast and 23km from the N’Goma West Hub floating production and storage facility (FPSO).

Agogo-2 well reached a total depth of 3,949 metres

The Agogo-2 well is drilled at 1,700 metres water depth and reached a total depth of 3,949 metres.

Agogo-2 drilling resulted in 58m net light oil (31° API) in sandstones of Miocene and Oligocene age with good petro-physical characteristics and confirming the extension of the Agogo reservoir to the north of the discovery well and below the salt diapirs.

Eni said that it has carried out the drilling for a highly deviated well, 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.

In addition, the Agogo-2 is expected to have a production capacity of more than 15,000 barrels of oil per day, according to the data acquired at the field.

Eni operates the Block 15/06 JV with a 36.8421% stake, along with Sonangol P&P holding 36.8421% and SSI Fifteen holds the remaining 26.3158%.

The first production from Agogo is expected to be started before the end of 2019 with a subsea tie back to the N’Goma FPSO, and the appraisal campaign is continued to estimate the full potential and size of the discovery.

Eni claims that it has been operating in Angola since 1980, and currently holds an equity production of approximately 150,000 barrels of oil equivalent per day in Angola.
