We operate two macro-areas, East Hub and West Hub, in Block 15/06, about 350 km north-west of the city of Luanda. West Hub entered production at the end of 2014, while production at East Hub began in February 2017, five months ahead of schedule, giving it one of the best time-to-markets in the industry. Much of our focus in this area is developing offshore oil fields and the block has seen Eni's first work in the deep water off Angola’s coast. The first phase involves the development of six fields (Sangos, Cinguvu, Mpungi, Ochigufu and Vandumbu) in the West Hub, which will be linked by 31 subsea wells. Of these, 18 are producing and 13 injecting to the floating production, storage and offloading (FPSO) unit Ngoma. For the East Hub area, development involves production in the fields of Cabaça South East and Cabaça Central UM8. These have 11 wells, six producing and five injecting, linked to FPSO Olombendo. Including the four start-ups in 2018 and the ramp-up of Vandumbu in the first quarter of 2019, Block 15/06 now produces about 140,000 barrels a day.
In January 2020 we started producing oil from the Agogo offshore deposit, located in Block 15/06 in Angolan waters, barely nine months after it was discovered, thanks to the operational synergies developed with the Floating Production Storage Offloading (FPSO) Ngoma. Start-up involved the drilling of the Agogo-1 well, which achieved a flow rate of around 10 thousand barrels of oil per day. In the same year, in February, we have successfully drilled Agogo-3, the second appraisal well of Agogo discovery, increasing by about 40% the estimate of oil in place, which is now of 1 billion barrels with further upside to be tested, and pave the way for its full field development with a third production hub.
