The well will test a 37 square kilometer structural feature approximately 30 kilometers off the coast of Tanzania within the Nyuni Block. No exploration drilling has taken place in the block to date.
The primary target at Nyuni comprises Lower Cretaceous (Neocomian) sands at a depth of approximately 2400m. These sands form the main reservoir at the nearby Songo Songo gas field, located approximately 18 kilometers to the southwest.
Additional targets include Tertiary (Eocene) sandstones and limestones.
The Nyuni prospect may hold recoverable reserves of up to 260 million barrels of oil (mmbo) or if gas is present, 870 billion cubic feet (bcf).
A period of approximately 70 days has been estimated for the well to reached its programmed total depth of approximately 3018 meters. After Nyuni-1, the rig will mobilize approximately 10 kilometers north to commence a test of the Okuza prospect.
