Pazflor Oil Field

Pazflor includes the Perpetua, Acacia, Zinia and Hortensia fields, which lie in the eastern portion of Block 17 approximately 150 kilometers from the Angolan coast.
At 325 metres long and 62 metres wide and weighing 120,000 tons, the Pazflor FPSO is the world’s largest floating production, storage and offloading vessel. Held in position by 16 subsea mooring connectors, the FPSO can store up to 1.9 million barrels in its hull and accommodate a total of 240 people
A water depth of up to 1,200 metres and an aggregate depth of 2,700 metres
The gigantic subsea gathering system covers 600 square kilometres
With 49 wells, 180 kilometres of flowlines and 10,000 tons of equipment on the seabed, the system is remarkable not only for its size, but also for its technical complexity
Pazflor’s 590 million barrels of proved and probable reserves make it an “elephant”.
Begonia Oil Field
- The Begonia development consists of five wells tied back to the Pazflor FPSO
- First oil is expected in 2024 and production volumes are expected to be 30,000 bpd

2000 - The Pazflor adventure begins with the discovery of the Perpetua field, the first of the four ones that make up Pazflor. This discovery is yet another exploration success for Total in Block 17.
2002-2003: discovery the three other fields, Hortensia, Zinia and Acacia.
December 2007: Total launches development of Pazflor.
2008 - KBR Awarded Contract to Provide Engineering, Procurement and Design Interface Services for Pazflor FPSO Topsides
March 2009: first development wells drilled.
Summer 2010: installation of the subsea equipment begins. The process takes a year and at times requires up to 6 pipe-lay vessels and 40 support vessels.
January 18, 2011: the FPSO departs its South Korean shipyard for Angola, a journey of more than 20,000 kilometres.
2011 - The giant Pazflor development was inaugurated by Angola's Minister of Petroleum, Chairman and CEO of Sonangol and Chairman and CEO of Total,
Final investment decision for Begonia oil field

A key technical challenge is to produce two very different grades of oil from four distinct fields: Perpetua, Hortensia and Zinia (reservoirs of Miocene age) and Acacia (reservoir of Oligocene age).
Producing the heavy, viscous oil from the three Miocene reservoirs, which account for two-thirds of the reserves, and the related fluid flow requirements represents a major technological challenge
