Nzanza-1 and Cinguvu-1 wells, located in Block 15/06 some 350km North-West of Luanda, were drilled in a water depth of 1400mt. They reached a total depth of respectively 3008mt and 3023mt. Both wells encountered oil pay in sands of Lower Miocene age with good reservoir characteristics.
During production tests, Nzanza-1 well produced an 18° API oil at rates above 1600 barrels per day (b/d). An analysis of the results indicates a potential for future production wells in excess of 5000 b/d per well, when associated to artificial lift. At the Cinguvu-1 well, the production test, limited by surface facilities, reached a flow of 6400 b/d of a 23° API oil.
After the Sangos-1 and N’Goma-1 discoveries in 2008 and Cabaca Norte-1 in 2009, these new discoveries confirm the potential of Block 15/06 in Angola, the company said. Tepa (Block 15/06) holds a 15% interest in the Block 15/06, operated by Eni.
These two recent discoveries, together with the former ones at Ngoma-1 and Sangos-1, all located in the north-western part of the permit, are being evaluated in view of the proceeding with a first development hub in Block 15/06.
In Angola, Total operated 491,000 barrels of oil equivalent per day (boe/d) in 2009, and its SEC equity production amounted to 191000boe/d. This equity production comes essentially from blocks 17, 0 and 14.
