Project Profile
Value: US$40.7 million
Location: 40 km offshore from the Nigerian coast, western edge of the Niger Delta, Nigeria
Production: ~22,000 bpd (net to Eni) - 2015
FPSO storage capacity: up to 900,000 bopd
FPSO oil treatment capacity: up to 45,000 bopd
Area: 1,983 km2 (490,010 acres)
Depth: 550 - 1,000 m
Start-up year: Q1 2015
OML 125 is located approximately 40 km offshore from the Nigerian coast on the western edge of the Niger Delta, at a water depth of 550 m to 1,000 m. Production began from the Abo field in 2003 and the field currently has four producing wells, two water injection wells and two gas injection wells. Oando Energy Resources acquired a 15% participating interest in OML125 and OML 134 blocks in 2008 and the project is operated by Nigeria Agip Exploration (NAE). Together with NAE, the work-over of Abo-9 well was completed, in the First Quarter of 2013. Abo-9 is a gas injection that will provide pressure support for the Anom01 and Anom02 producing reservoirs. Gas injection is due to commence in Q1 2014. The partners commenced the Abo phase 3 development with the sidetrack of Abo-4 well, which drilled and completed on the B207 reservoir and was producing light and medium oil at a rate of 1,380 bbls/d (gross, WI) on 31 December, 2013. Followed by an up-dip sidetrack of Abo-3 on B200, which only flowed for ~72 hours during testing due to a significant sand blockage in the flow line, on which repairs are underway. Finally, the Abo-8 well was completed as an oil producer on the Anom01 and Anom02 reservoirs. Production has not commenced from Abo-8 as the required flow line is a long lead item, delivery of which is expected to be Q1 2015.
Abo field
Abo, Nigeria\'s first deepwater oil field is located in the southeastern part of Oil Mining Lease (OML) 125, about 34 miles (55 kilometres) off the coast in water depths ranging from 1,476 to 2,461 feet (450 to 750 metres). The oil field is estimated to hold more than 700 million barrels in reserves. Development of the field consisted of several subsea wells connected to the Abo FPSO, which processes, stores and discharges oil into export tankers. The FPSO has a storage capacity of 900,000 bopd and an oil treatment capacity of up to 45,000 bopd, a water injection capacity of 30,000 bwpd and a gas injection capacity of 35 MMcf/d. Due to the Government\'s regulations of zero flaring, the associated gas is re-injected into the reservoir. Prosafe received a contract for the provision of an FPSO for the Abo field. The company supplied the Suexmax Grey Warrior tanker, and converted, operates and owns the unit on a 100% basis. Measuring 919 feet (280 metres) in length, the tanker was converted in 2002, and was deployed to the field in the first quarter of 2003. The Abo field came online in April 2003, and produces about 40,000 bopd.
Future Plans:
- Drilling of the Abo-12 well, which has commenced. This is a development well with an exploration tail. The well is planned to further drain the Anom02 reservoir and explore the shallow A197 reservoir and the deeper Anom3 reservoir.
- Until the re-processed seismic data for OML 125 has been reviewed, and prospectivity re-assessed, there are no further plans to drill exploration wells on any of the other prospects in OML 125 after 2015.
