Egina

Egina Oil Field Profile

Location and Geology

• The Egina oil field is located approximately 150 kilometers off the coast of Nigeria in the Gulf of Guinea, within the Oil Mining Lease (OML) 130 block.
• It is situated at water depths ranging from 1,400 to 1,750 meters, making it one of the deepest offshore projects operated by Total.

Discovery and Reserves

• The Egina oil field was discovered in December 2003 by the Egina-1 well. This was followed by appraisal wells Egina-2 in October 2004, and additional wells Egina-3, Egina-4, and Egina-5 drilled between 2006 and 2007.
• The field is estimated to hold around 550 million barrels of oil reserves in Miocene sands, with the oil rated at 28° API.

Partners and Ownership

• The project is operated by Total Upstream Nigeria Ltd. with a 24% interest.
• Other partners include China National Offshore Oil Corporation (CNOOC) with 45%, Petrobras with 16%, and South Atlantic Petroleum (Sapetro) with 15%.

Project Development and Infrastructure

• The project began construction in December 2013, following approvals from the National Petroleum Investment Management Services (NAPIMS) in 2008 and final approval from Nigerian authorities in 2009.
• The field was initially planned to be developed as a subsea tieback to the Akpo FPSO, but due to significant discoveries, it was developed as a standalone project.
• The development includes 44 subsea wells drilled by the West Jupiter drillship, tied back to a Floating Production, Storage, and Offloading (FPSO) unit.
• The FPSO measures 330 meters in length, 61 meters in width, and 34 meters in height, with a topside weight of 47,500 tonnes. It has a production capacity of 208,000 barrels of oil per day and a storage capacity of 2.3 million barrels of oil.

Subsea Infrastructure

• The subsea production system includes risers, 52 kilometers of oil and water injection flowlines, 12 flexible jumpers, 20 kilometers of gas export pipelines, 80 kilometers of umbilicals, and subsea manifolds.
• TechnipFMC was responsible for the full subsea production system (SPS), including subsea trees, wellheads, manifolds, and associated control systems. They also supplied flexible piping and steel tube umbilicals.

Contractors and Suppliers

• Samsung Heavy Industries (SHI) was awarded a turnkey EPCIC contract for the FPSO in 2013, worth $3 billion. SHI subcontracted Vallourec for pipeline segments and other steel supplies.
• Saipem was awarded a $3 billion EPCI contract for the subsea production system in June 2013. They performed fabrication work at the Saipem Rumoulumeni Yard in Port Harcourt, Nigeria.
• TechnipFMC received a $1.2 billion EPCI contract for the subsea production system and subcontracted Aveon Offshore for fabrication services.
• Dover Engineering, along with J P Kenny Engineering and MCS Kenny, completed the front-end engineering and design (FEED) work for the subsea production systems and umbilicals in July 2010.
• LADOL Integrated Logistics Enterprise provided logistics services during the construction of the FPSO unit.

Production and Impact

• The Egina oil field commenced production in December 2018 and is expected to produce 200,000 barrels of oil per day, accounting for approximately 10% of Nigeria’s total oil production.
• The project has significant local content, with a focus on technology transfer and training of the local workforce. Locally worked hours reached about 75% during the project, and it employed around 1,500 people at its peak construction period.

Economic and Social Impact

• The Egina project is the first major deepwater development in Nigeria since the Nigerian Content Act was signed into law in 2010. It has contributed significantly to local development, including infrastructure upgrades and job creation.
• The project has also led to the establishment of new facilities, such as a subsea services workshop in Onne, Port Harcourt, which serves as a service base for the region.

In summary, the Egina oil field is a landmark ultra-deepwater project that showcases advanced engineering and local content integration, contributing significantly to Nigeria's oil production and economic development.
