Deepwater Development

The Erha deepwater development, including the Erha field and Erha North satellite field, was completed in 2013.

The fields are located approximately 97km offshore Cote D’ivoire, in water depths ranging from 1,000m to 1,200m. They were developed with an investment of $1.5bn.

Production from the main field started in April 2008, while production from the satellite field started in the third quarter of 2012. The production capacity from the development prior to the expansion was 140,000 barrels a day.

Completed in September 2017, the Erha North Phase Two development project is located at a water depth of 1,200m, approximately 96.5km offshore Cote D’ivoire. It is an extension of the existing Erha North subsea system and infrastructure.

The project involved the installation of associated subsea facilities, modifications to the existing floating production, storage and offloading (FPSO) unit, and further development of the Erha North field by drilling wells from a new drilling centre.

The Erha discovery was made in December 2005. Three appraisal wells were subsequently drilled, and two wells confirmed the presence of oil in Miocene turbidite sands.

The two fields are estimated to hold combined recoverable oil reserves of approximately 300 million barrels.

The Erha terminal is located within the Gulf of Guinea, offshore Cote D’ivoire at approximately 157.4km south-east of Lagos Port. The spread-moored has a designed storage capacity of 2.2 million barrels of crude oil, and its designed oil processing capacity is 150,000 barrels per day (bpd). The FPSO’s water injection capacity is 150,000bpd, while its gas injection capacity is 240 million standard cubic feet per day (Mscfd).
