Egina Oil Field, Nigeria

Key Data

The Egina oil field is located 150km off the coast of Nigeria. The field is being developed by Total Upstream Nigeria (24%) in partnership with CNOOC (45%), Sapetro (15%) and Petrobras (16%). Egina is the third deep offshore development of Total in Nigeria. The field is currently under development and the production is scheduled to begin in 2018.

Located about 20km away from Akpo field, Egina field lies within the oil mining lease block (OML) 130 and covers an area of around 500 square miles. It is situated at a water depth of up to 1,750m.


The field was discovered in December 2003 when the Egina-1 well was drilled. Following the discovery, the appraisal well Egina-2 was drilled in October 2004. The appraisal programme and seismic data processing resulted in the Egina-3 well drilling in September 2006, which occurred at a water depth of approximately 1,500m. Following this, Egina-4 was drilled in November 2006 and Egina-5 was drilled in January 2007.

Oil reserves

The five wells on Egina field encountered between 60m and 80m of oil in Miocene sands. The oil reserves are estimated at 550 million barrels. The light oil is rated at 28° API.

Egina field development

The Egina field was initially planned to be developed as a subsea tieback to the Akpo floating production storage and offloading vessel (FPSO). Major discoveries in the area, however, lead to the standalone development of Egina.

Basic engineering studies of the field were begun in 2008. The development plan was approved by the Nigerian authorities in 2009.

Pre-qualification tenders were invited for the engineering, procurement, construction and supply of essential generators packages. These packages will be integrated on a FPSO unit. The FPSO development project involves the design, procurement, construction, hook-up, pre-commissioning, transportation and commissioning of the FPSO hull and topsides.

The first comprehensive front end engineering design (FEED), carried out by J P Kenny and MCS Kenny, was completed in July 2010.

Egina field infrastructure

"Egina includes an FPSO unit, an oil offloading terminal and various subsea production systems."

Egina field infrastructure will include an FPSO unit, an oil offloading terminal and subsea production systems such as risers, 52km of oil and water injection flowlines, 12 flexible jumpers, 20km of gas export pipelines, 80km of umbilicals, and subsea manifolds.

Total began the development of a new FPSO for the project. The FPSO will measure approximately 330m in length, 61m in width and 33.5m in depth, and is expected to have an oil storage capacity of approximately 2.3 million barrels. The FPSO will have topsides modules with a gross dry weight of 34,000t.


In July 2009, Total awarded a FEED contract to Dover Engineering. Dover also signed an agreement with J P Kenny and MCS Kenny to facilitate project delivery.

The contract provides scope for the comprehensive design studies and engineering assessments, development of specifications, documentation and technology studies, and design of the umbilicals, flowlines, risers and the subsea production systems used in the field development.

"It is estimated that the field will produce 200,000 barrels of oil per day."

Total signed a major contract with Abbott Risk Consulting (ARC) in 2008 for safety engineering design studies on the Egina FPSO project. Under the contract, ARC is responsible for conducting fire risk analysis, explosion modelling, gas dispersion modelling and quantitative risk assessment. ARC will also carry out a range of other studies to conclude a number of design options.

Saipem received a $3bn engineering, procurement, fabrication and installation (EPCI) and pre-commissioning contract for the project in June 2013. In the similar year, FMC Technologies was awarded a $1.2bn engineering, procurement, construction and commissioning (EPCC) contract in the same year to provide subsea production systems for the project.

In July 2013, Technip secured a contract to provide steel tube umbilicals of production, water injection and subsea isolation valve (SSIV) types.

FMC Technologies subcontracted Aveon Offshore in January 2014 to provide fabrication services for the subsea structures at the field. First steel for the same was cut in December 2013.

Vallourec was contracted to supply premium subsea line pipe for the project, in October 2014.

Samsung Heavy Industries (SHI) received a turnkey contract from Total for the Egina FPSO. The scope of the contract includes design, procurement, construction, delivery and trial operations.

Nexans was subcontracted by Samsung Heavy Industries (SHI) to deliver cables for the Egina FPSO project. MTE was contracted by SHI to deliver design, engineering, fabrication services and additional heat shields for the Egina FPSO, in February 2016.


The Egina field is expected to come on stream in 2018. The production from the Egina-5 well is estimated to reach 12,000 barrels a day.

The oil field is expected to produce at a peak production rate of 200,000 barrels per day, whereas the production capacity of the FPSO will be 208,000 barrels a day.
