Project development

The Southern Swamp area comprises of 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 gathering pipelines and a new evacuation pipeline that will be installed.

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

The project is being developed by three Engineering, Procurement, and Construction (EPC) contracts:

  • EPC for the production facilities – this was awarded to a consortium led by SAIPEM Contracting Nigeria Limited
  • EPC for the gas gathering lines – this was awarded to Daewoo Nigeria Limited
  • EPC for the evacuation line – this was awarded to SAIDEL Nigeria Limited


A system from technology firm Twister is being 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 lies 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 freedom to operate agreements guided by the global memoranda of understanding between SPDC and local communities.

SSAGS has provided employment opportunities for up to 1,000 local people also generates business for local suppliers.
