Total announced that its subsidiary, TEPA (Block 15/06), Limited, and its partners have made two important oil discoveries in Angola at the Nzanza-1 and Cinguvu-1 wells, in the deep waters of the Angolan offshore.
Nzanza-1 and Cinguvu-1 wells, located in Block 15/06 some 350 kilometers North-West of Luanda, were drilled in a water depth of 1,400 meters. They reached a total depth of respectively 3,008 meters and 3,023 meters. 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 1,600 barrels per day (b/d). An analysis of the results indicates a potential for future production wells in excess of 5,000 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 6,400 b/d of a 23° API oil.
After the Sangos-1 and N’Goma-1 discoveries in 2008 and Cabaça Norte-1 in 2009, these new discoveries confirm the potential of Block 15/06 in Angola.
TEPA (Block 15/06), Limited, holds a 15% interest in the Block 15/06, operated by Eni.
Block 15/06 development hubs
These two recent discoveries, together with the former ones at Ngoma-1 and Sangos-1, all located in the nortwestern part of the permit, are being evaluated in view of the proceeding with a first development hub in Block 15/06.
Total Exploration & Production in Angola
Total is present in Angola since 1953. In Angola, Total operated 491,000 barrels of oil equivalent per day (boe/d) in 2009, and its SEC equity production amounted to 191,000 boe/d. This equity production comes essentially from blocks 17, 0 and 14.
Deep offshore Block 17, operated by Total with a 40% interest, is Total’s principal asset in Angola. It is composed of four major zones: Girassol-Rosa and Dalia, which are currently producing; Pazflor, a project under construction for a production start in 2011; and CLOV (based on the Cravo, Lirio, Orquidea and Violeta discoveries), a project for which the final investment decision should be taken soon.
Total is also the operator with a 30% stake in the ultra deep offshore Block 32, on which twelve discoveries were made, confirming the oil potential of the block. Development studies for a first production zone in the central south eastern portion of the block are underway.
In addition, the Angola LNG project for the construction of a liquefaction plant near Soyo is designed to bring the country’s natural gas reserves to market. This project, on which Total holds a 13.6% stake, will be supplied by the associated gas from the fields on blocks 0, 14, 15, 17 and 18. The project is underway with production expected to begin in 2012.
