Project development

The Southern Swamp area comprises 16 fields, of which 12 are currently producing. The fields lie in the coastal swamp area, 65 km south of Warri, with 100 oil wells and flow lines currently producing through four flow stations (Benisede, Opukushi, Ogbotobo and Tunu). A new field logistics base at Tunu is close to completion. Oil is transported via the Trans Ramos pipeline to the Forcados terminal.

Under the SSAGS project, gas will be exported to Escravos Lagos Pipeline System (ELPS) via the existing pipelines and a new pipeline that will be installed.

Final investment decision was taken for the project on April 16, 2012.  

Contracts for production facilities and gathering pipelines were awarded to Saipem Contracting Nigeria Ltd and to Daewoo Nigeria Ltd.


A system from technology firm Twister is used to remove any liquids from the natural gas to meet export specifications – a process called hydro-carbon dew pointing.

Environment and society

The project cuts across 23 communities and two states (Delta and Bayelsa) in the Niger Delta.

The project liaises with local communities on how they would like to benefit from social investment through so-called “freedom to operate” agreements guided by the global memoranda of understanding between SPDC and local communities.

SSAGS creates jobs for local people and generates business for local suppliers.
