Pazflor

Pazflor Oil Project Profile

Location and Geography

• The Pazflor oil project is located offshore Angola, specifically in Block 17, approximately 150 km (93 miles) off the coast of Luanda and 40 km (25 miles) northeast of the Dalia field.
• The project spans an area of over 600 square kilometers (232 square miles) with a north-to-south axis of more than 30 km (19 miles).

Water Depth and Reservoirs

• The project is situated in water depths ranging from 600 to 1,200 meters (1,968 to 3,937 feet).
• It targets two independent reservoir structures: the Oligocene reservoirs at depths of 1,000 to 1,200 meters, containing light oil (35°-38° API), and the Miocene reservoirs at depths of 600 to 900 meters, containing heavy oil (17°-22° API).

Fields Included

• The Pazflor project encompasses four fields: Acacia, Hortensia, Perpetua, and Zinia.

Operator and Ownership

• The project is operated by Total E&P Angola, a wholly owned subsidiary of TotalEnergies, with a 40% interest. Other partners include StatoilHydro (23.33%), Esso Exploration Angola (Block 17) Ltd (20%), and BP Exploration (Angola) Ltd (16.67%).

Production and Processing

• The project has a processing capacity of 200,000 barrels of oil per day (bpd) and 150 million cubic feet of gas per day (mmcf/d). The FPSO has a storage capacity of about 1.9 million barrels of crude oil.
• Production started in 2011 and is expected to ramp up to a full production capacity of 220,000 bpd over time.

Infrastructure and Technology

• The project features a vast subsea gathering network, the most complex ever built in Angola, including 180 km (111.8 miles) of lines tying in 49 subsea wells (25 producers, 22 water injectors, and two gas injectors) and three subsea separation units.
• The FPSO, built by Daewoo Shipbuilding and Marine Engineering (DSME), is the largest in the world, measuring 325 meters (1,066 feet) long, 62 meters (203 feet) wide, and weighing over 120,000 metric tons. It is held in position by 16 subsea mooring connectors.
• The project utilizes subsea gas/liquid separation and liquid boosting to handle the heavy, viscous oil from the Miocene reservoirs, a technological innovation that was a world first on this scale.

Subsea Systems

• FMC delivered 49 subsea trees, wellhead systems, production manifold systems, and other subsea equipment. The project also includes gas export and flowline connection systems, and ROV tooling for installation and start-up activities.
• Technip and Acergy were involved in the engineering, procurement, fabrication, and installation of the subsea infrastructure, including flowlines, umbilicals, and manifolds.

Reserves and Production

• The project has estimated proved and probable reserves of 590 million barrels of oil.
• The production design capacity is approximately 80.3 million barrels per year.

Development Timeline

• The project received sanction in 2008, with drilling starting in 2009 and oil production commencing in 2011.

Facilities and Personnel

• The FPSO has living quarters for 220 operation and maintenance personnel, designed for a 20-year service life.
• The facilities are planned to meet strict health, safety, and environmental standards.

Key Partners and Contractors

• Total E&P Angola is the operator, with key partners including StatoilHydro, Esso Exploration Angola, and BP Exploration (Angola) Ltd.
• Major contractors include Daewoo Shipbuilding and Marine Engineering (DSME) for the FPSO, Technip and Acergy for subsea work, and FMC for subsea equipment.

The Pazflor oil project is a significant deepwater development that showcases advanced technological innovations in subsea production and separation, highlighting TotalEnergies' expertise in complex offshore environments.
