Estimated volumes for the Calao South discovery are up to five trillion cubic feet (tcf) of gas and 450 million barrels (mbbl) of condensate, equating to approximately 1.4 billion barrels of oil.
Eni holds a 90% operating stake in Block CI-501, with Petroci Holding owning the remaining 10%.
The Murene South-1X well is situated around 8km south-west of the Murene-1X discovery well in the neighbouring CI-205 concession. It is the first exploration well in CI-501.
The Saipem Santorini drill-ship drilled the well to a depth of approximately 5,000m in waters 2,200m deep, where it was subjected to a comprehensive data acquisition programme.

By GlobalDataMurene South-1X identified hydrocarbon-bearing intervals with a gross thickness of around 50m, demonstrating its petrophysical properties.
The well underwent an extensive data acquisition process and will be subjected to a full conventional drill stem test to evaluate the Calao discovery’s production potential.
Calao South is the second-largest find in the country after the Eni-operated Baleine field.
Currently, the Baleine field produces more than 62,000 barrels (bbl) of oil and over 75 million cubic feet (mcf) of gas per day from its first two phases.
With phase three set to commence, daily production is forecast to increase to 150,000bbl of oil and 200mcf of gas.
Since 2015, Eni has operated in Côte d’Ivoire and holds interests in various exploration blocks, apart from CI-501.
These include nine other blocks in collaboration with Petroci Holding, and Baleine AEE in partnership with Petroci Holding, Vitol, and SOCAR, pending governmental approvals.
Recently, Azule Energy, a 50:50 joint venture between Eni and bp, reported a major oil discovery at the Algaita-01 exploration well in Block 15/06 offshore Angola, roughly 18km from the Olombendo FPSO.
Azule Energy operates Block 15/06 with a 36.84% interest, in collaboration with SSI (26.32%) and Sonangol E&P (36.84%).
Initial estimates suggest the presence of approximately 500mbbl of oil in place at the Angolan discovery.
