A group led by Eni’s Angolan unit has reported two deepwater oil discoveries in Block 15/06 about 350 km northwest of Luanda, Angola.
Nzanza-1 and Cinguvu-1 found Lower Miocene oil pay with good reservoir characteristics in 1,400 m of water. Total depths are 3,008 m and 3,023 m, respectively.
Nzanza-1 made more than 1,600 b/d of 18° gravity oil on production tests. Analysis of the results indicates potential for future production wells in excess of 5,000 b/d/well on artificial lift.
Capacity of surface facilities limited Cinguvu-1’s production test rate to 6,400 b/d of 23° gravity oil.
Nzanza and Cinguvu follow the group’s Sangos-1 and N’Goma-1 discoveries in 2008 and Cabaca Norte-1 in 2009 in confirm the block’s potential.
Angola’s state Sonangol EP is the concessionaire for Block 15/06. Block interests are Eni 35%, SSI Fifteen Ltd. 20%, Sonangol Pesquisa e Producao SA 15%, Falcon Oil Holding Angola SA 5%, Petrobras International (Braspetro) BV 5%, and Statoil Angola Block 15/06 AS 5%.
