CLOV development in Angola approved
The development of the CLOV project on Block 17 in Angola has been approved by the partners and the principal contracts awarded. Statoil has a 23.33% stake in Block 17. The CLOV project is the fourth development pole in this deepwater block after Girassol, Dalia and Pazflor. In the plan now approved by the partners, drilling is scheduled to commence in 2012 and first oil is expected in 2014.
Located around 140 kilometres from Luanda and 40 kilometres northwest of Dalia in water depths ranging from 1,100 to 1,400 metres, the CLOV development will bring on stream four fields: Cravo, Lirio, Orquidea and Violeta.
The overall development plan for CLOV uses technologies that have already proven effective on Girassol, Dalia and Pazflor. A total of 34 subsea wells will be tied back to the CLOV Floating Production, Storage and Offloading (FPSO) unit, which will have a processing capacity of 160,000 barrels of oil per day at plateau and a storage capacity of 1.78 million barrels.
The CLOV FPSO will handle two types of oil: light oil with an API gravity between 32 to 35° API from Oligocene reservoirs (Cravo-Lirio) and a 20 to 30° API gravity oil (more viscous) from Miocene reservoirs (Orquidea-Violeta). Both oil streams will be commingled and processed in one single train before storage.
The installations have been designed to limit the FPSO’s environmental impact. Measures include eliminating flaring under normal operating conditions, recovering heat from turbine exhaust and recovering vent gases.
Total E&P Angola operates Block 17, with a 40% interest, alongside Statoil (23.33%), Esso Exploration Angola (Block 17) Limited (20%) and BP Exploration (Angola) Ltd (16.67%).
