The Abo oil field is located in the North-Western sector of the Nigerian Deepwaters, specifically within the Oil Mining Lease (OML) 125.
Operator and Partners
The operator of the Abo oil field is ENI.
The partners in the project include ENI with a 50.19% stake and Shell Nigeria Exploration and Production Company (SNEPCO) with a 49.81% stake.
Production and Reserves
The Abo Central field is the first producing Nigerian deepwater oil field.
Production at the Abo field began in 2003.
While specific reserve estimates are not provided in the source, the field is part of the broader Nigerian deepwater oil and gas reserves.
Field Development
The field development plan was approved in 2001, followed by the Final Investment Decision in the same year.
The project involved the conversion of a Floating Production, Storage, and Offloading (FPSO) vessel by Keppel, which was delivered in 2002.
Technical Specifications
The ABO FPSO has a storage capacity of 900,000 barrels of oil.
It has an oil treatment capacity of up to 45,000 barrels per day (bopd), a water injection capacity of 30,000 barrels per day (bwpd), and a gas injection capacity of 35 million standard cubic feet per day (MMSCFD).
Contractors and Service Providers
Key contractors involved in the project include:
Keppel: FSPO conversion.
Saipem: Abo Field Development feasibility and conceptual design, Front-End Engineering Design (FEED).
Technip: Engineering, procurement, and installation of flexible lines, umbilicals, and the FPSO mooring system.
Ceona: Installation work on the ABO 12 well.
Geology and Water Depth
The Abo Central field is developed in water depths ranging between 500 meters and 800 meters.
Production and Operations
The associated gas from the field is re-injected into the reservoir.
The field's production infrastructure includes the FPSO and associated subsea facilities.
Additional Developments
In 2008, Oando acquired a share of the licence for OML 125, which includes the Abo field.
