ENI strikes Lower Miocene oil offshore Angola with Nzanza-1, Cinguvu-1

Eni has announced two new oil discoveries in Block 15/06, Nzanza-1 and Cinguvu-1, offshore Angola. Statoil has a 5% interest in this block. Both of the discovery wells, located around 350 km northwest of Luanda in 1,400 m of water, successfully reached the objectives in the Lower Miocene targets, where oil pay sands with good reservoir characteristics were encountered. Operations were completed in December 2009 for Nzanza-1 and in February 2010 for Cinguvu-1. The discoveries will allow the operators to proceed with the currently ongoing pre-development phase of the “Western hub.”

The success of these two wells follow the recent success of Cabaça Norte-1, which had three consecutive oil discoveries in the block in 2009, and five, including Sangos and N’Goma, in 2008.
