[Angola] Pazflor

Unread post by escveritas »

August 26, 2011: Total, operator of Block 17, today announced that the giant Pazflor field offshore Angola has come on stream ahead of the initial schedule. The Pazflor field lies 150 kilometres off Luanda in water depths ranging from 600 to 1,200 metres and has estimated proved and probable reserves of 590 million barrels. The field will gradually ramp up to its full production capacity of 220,000 barrels per day over the coming months.

“Pazflor’s start-up, several weeks ahead of schedule and within budget, is a remarkable achievement of the teams involved. The support and trust of Sonangol, our concession holder and partner, also made an invaluable contribution to our efficiency” says Yves-Louis Darricarrère, President Exploration & Production at Total. “Pazflor required a development effort on the same scale as the field. Paving a way with new technologies, the project showcases Total’s expertise in highly complex environments. The project facilities have been designed and thoroughly tested in accordance with the strictest health, safety and environmental standards. This is another step in the ongoing saga of our deep offshore feats, begun right here in Angola. Deepwater developments are a core driver of our future production growth.”

Pazflor comprises a vast subsea gathering network, the most complex ever built in Angola: 180 kilometres of lines tying in 49 subsea wells, 10,000 metric tons of subsea equipment and the giant Pazflor floating production, storage and offloading (FPSO) vessel. Held in position by 16 subsea mooring connectors, with its 325 metres long, 62 metres wide and a weight of more than 120,000 metric tons, the FPSO is the largest in the world. It can store up to 1.9 million barrels of oil that is then exported to tankers via an offloading buoy. The associated gas is reinjected into the reservoir, but could also be exported to the Angola LNG plant once the latter becomes operational.

A key technical challenge was producing two very different grades of oil from four separate reservoirs. Producing the heavy, viscous oil from the three Miocene reservoirs, which account for two-thirds of the reserves, and the related flow assurance constraints, represented a major challenge. The gas has to be separated from the liquids on the seabed so that the viscous liquids can then be pumped to the surface. The design and installation of subsea gas-liquid separation units and pumps are a world first on this scale. The pumps were purpose designed and tested for Pazflor.

Total’s wholly owned subsidiary Total E&P Angola operates Block 17, with a 40% interest, while Sonangol is the concession holder. The other partners are Statoil ASA (23.3%), Esso Exploration Angola (Block 17) Limited (20%) and BP Exploration (Angola) Ltd (16.67%).

November 22, 2011: The giant Pazflor development, which lies 150 kilometres offshore Luanda in Angola, was inaugurated today at a ceremony attended by José Botelho de Vasconcelos, Angola's Minister of Petroleum, Christophe de Margerie, Chairman and CEO of Total, Yves-Louis Darricarrère, President of Exploration & Production at Total; and representatives of Total and the local authorities.

“We are very proud to be inaugurating Pazflor today. With this bold project, Total has pushed back the boundaries of technology. I would like to congratulate all of our teams for making it possible to successfully complete one of the world’s most outstanding oil developments. I would also like to thank our concession holder Sonangol and our partners for their support. Following on from Girassol and Dalia, Pazflor is a new chapter in the remarkable twinned story of Total, its contractors and Angola, allowing us to successfully pursue the Block 17 adventure” Christophe de Margerie commented during the ceremony.

The field came on stream on the 24th of August. Output will reach 220,000 barrels per day and will make Total the leading oil operator in Angola and the African deepwater industry. This position should be cemented when the CLOV project begins production, scheduled for 2014.

Sonangol is the concession holder for Block 17, which is operated by Total E&P Angola, a wholly owned Total subsidiary, with a 40% interest. The other partners are Statoil ASA (23.33%), Esso Exploration Angola (Block 17) Limited (20%) and BP Exploration (Angola) Ltd (16.67%).

Pazflor facts and figures: a people-led technological feat

As many as 4,500 people on four different continents were involved in the project at the same time, for a total of 32 million hours worked, including 3.6 million in Angola. The global investment was approximately $9 billion.

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, six times the area of Paris.

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”.

Pazflor milestones: the history of a giant

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.

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.

August 24, 2011: Pazflor comes on stream several weeks ahead of schedule and on budget.

September 3, 2011: the first subsea separation unit is successfully commissioned, a world first.

Subsea separation, a world technological first

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. The gas has to be separated from the liquids on the mudline so that the viscous liquids can then be pumped to the surface.

The design and installation of subsea gas-liquid separation and pumping units on this scale constituted a world first. The pumps were purpose designed, tested and fabricated for Pazflor.

Total Exploration & Production in Angola

Total has been present in Angola since 1953. In 2010, the Group’s operated production in Angola averaged 460,000 barrels of oil equivalent per day and its SEC* equity production amounted to 163,000 barrels of oil equivalent per day, accounting for 7% of Total's output. Most of this production comes from Blocks 17, 0 and 14.

Total's main asset in Angola is deepwater Block 17, which it operates with a 40% interest. The deep offshore block contains four major hubs: Girassol-Rosa, Dalia, Pazflor, which are currently in production, and CLOV (Cravo, Lirio, Orquidea and Violeta), whose is currently under development.

The Group also operates the ultra-deepwater Block 32, in which it holds a 30% stake. Twelve discoveries have confirmed the block's potential for oil production, and conceptual development studies are underway on a first production area in the central southeastern sector of the block.

In addition, the Angola LNG project is building a liquefaction plant near Soyo to bring the country’s natural gas reserves to market. Total has a 13.6% interest in the project. The plant will initially be supplied with associated gas from fields on Blocks 0, 14, 15, 17 and 18.It is expected to come on stream in 2012.

After validation of the helideck by the INAVIC offshore Luanda and the site visit on April 11th of the Angolan authorities (Health, Customs, Immigration and Port Authorities), the activities for the three coming weeks will mainly be focused on the mooring operations of the FPSO. During these few weeks of travel, nearly 200 people continued to work on the FPSO to optimize the on board facilities preparation for the mooring activities and commissioning.
In all, more than 180,000 work hours without lost time accident. These good results join up with those of the offshore installation campaign, since the one million working hours has been exceeded recently, also without a lost time accident.

The FPSO is a floating production, storage and offloading vessel. The FPSO Pazflor will be shortly connected to subsea separation units (SSU), in 800 meters of water in Block 17 offshore Angola.
Pazflor is the first-ever project anywhere to deploy a development plan based on gas/liquid separation at the mudline spanning several reservoirs.

ANGOLA: TOTAL STARTS PRODUCTION FROM ZINIA PHASE 2, SUCCESSFUL SHORT-CYCLE DEVELOPMENT ON BLOCK 17

Paris, May 6, 2021 – Total, operator of Block 17 in Angola, together with the Angolan National Oil, Gas and Biofuels Agency, announce the start of production from Zinia Phase 2 short-cycle project, connected to existing Pazflor’s FPSO (Floating Production, Storage and Offloading unit). The project includes the drilling of nine wells and is expected to reach a production of 40,000 barrels of oil per day by mid-2022.

Located in water depths from 600 to 1,200 meters and about 150 kilometers from the Angolan coast, Zinia Phase 2 resources are estimated at 65 million barrels of oil.

The development of this project was carried out according to schedule and for a CAPEX more than 10% below budget, representing a saving of 150 million dollars. It involved more than 3 million manhours of work, of which 2 million were performed in Angola, without any incident.

“The successful start-up of this project, despite the challenges that have arisen as a result of the pandemic, demonstrates Total’s commitment to ensure a sustainable output on Block 17, for which the production license was recently extended until 2045. Zinia Phase 2 project reflects the quality of short cycle projects in Angola with high return on investment”, said Nicolas Terraz, President Africa, Exploration and Production at Total.

Paulino Jerónimo, CEO of the National Oil, Gas and Biofuels Agency, commented as follows, “Zinia Phase 2 is a key project for Angola that comes at the right time to sustain the production of the country. We welcome our collaboration with Total in Angola, that keeps investing with its partners in the development of the country oil resources”.

Block 17 is operated by Total with a 38% stake, alongside with Equinor (22.16%), ExxonMobil (19%), BP Exploration Angola Ltd (15.84%) and Sonangol P&P (5%). The contractor group operates four FPSOs in the main production areas of the block, namely Girassol, Dalia, Pazflor and CLOV.
