Project Description
Discovered in 2000, the Akpo field is located in ultra deepwater of Nigeria. Situated on OML 130 approximately 124 miles (200 kilometers) from Port Harcourt, Akpo's water depths range from 3,609 to 5,577 feet (1,100 to 1,700 meters).

A gas and condensate field, Akpo is operated by Total, holding a 24% interest in the project. Other participants in the license include CNOOC with 45% interest, Petrobras with 16%, NNPC with 10% and Sapetro with 5%.

Field Development

Beginning in 2005, the Akpo field development project includes 44 wells -- 22 production wells, 20 water injection wells and two gas injection -- of which 22 have already been drilled, tied-back to an FPSO.

Discovered in 2000, the Akpo field is located in ultra deepwater of Nigeria. Situated on OML 130 approximately 124 miles (200 kilometers) from Port Harcourt, Akpo's water depths range from 3,609 to 5,577 feet (1,100 to 1,700 meters).

A gas and condensate field, Akpo is operated by Total, holding a 24% interest in the project. Other participants in the license include CNOOC with 45% interest, Petrobras with 16%, NNPC with 10% and Sapetro with 5%.

Field Development

Beginning in 2005, the Akpo field development project includes 44 wells -- 22 production wells, 20 water injection wells and two gas injection -- of which 22 have already been drilled, tied-back to an FPSO.

The subsea infrastructure consists of 110 kilometers of a complex array of high pressure-high temperature subsea flowlines connected by steel catenary risers to an FPSO.

In May 2005, Cameron was awarded the $340 million contract for the subsea systems on the field, including 44 subsea wells, xmas trees and manifolds. Cameron then subcontracted Roxar to provide the multiphase flow meters for the development, as well as the subsea sand monitors and pig detectors.

With a storage capacity of 2 million barrels of condensate, the Akpo FPSO has the capacity to produce 185,000 boepd. Measuring 1,017 feet (310 meters) long and 200 feet (61 meters) wide, the vessel includes two processing trains to separate gas and water, 17 topside modules, and accommodations for a crew of 240. Moored in 4,347 feet (1,325 meters) of water by 12 anchor lines, the Akpo FPSO has a dry weight of 100,000 tons (90,718 tonnes).

For a consideration of $1.8 billion, a Technip/Hyundai Heavy Industries consortium was awarded the engineering, construction, procurement and installation of the Akpo FPSO. Technip managed the overall project and engineering for the vessel, and HHI executed the FPSO's hull and topsides construction and integration. Nexan was subcontracted to provide the 736 miles (1,185 kilometers) of offshore cables for power and instrumentation on the FPSO.

In an $850 million contract, Saipem was awarded the engineering, procurement, construction, installation and commissioning of the umbilicals, flowlines and risers, as well as the oil loading terminal, the FPSO mooring system and the gas export pipeline from the Akpo FPSO to the Amenam AMP2 platform. Offshore installation is being carried out by the Saibos FDS and the Saipem 3000 vessels.

Production

Akpo achieved first production in March 2009, and peak production of 175,000 barrels of condensate a day and 320 MMcf/d of gas is expected in the summer of 2009. Nearly 80% of this output is in the form of condensate, which is exported via a buoy located just 1.2 miles (2 kilometers) from the FPSO. The gas is piped 90 miles (150 kilometers) to the Amenam Kpono gas production platform; from there, it is sent via pipeline to the Bonny liquefaction plant.

BJ Services Completes Major Subsea Ops Offshore Nigeria
Type: Subsea Equipment

Nov. 2009 - A subsea pipeline pre-commissioning operation performed by BJ Services Company was completed on the Akpo field in the Oil Mining Lease 130 Block, roughly 124 miles south of Port Harcourt, Nigeria in water depths of 3,936 to 4,593 feet (1,200 to 1,400 meters). The company performed a series of pre-commissioning services on the field's flowlines and umbilicals. Akpo achieved first production in March 2009, and peak production of 175,000 barrels of condensate a day and 320 MMcf/d of gas is expected during the fourth quarter of 2009.

Total Starts-Up of Production at Akpo Offshore Nigeria
Type: Production Start

Mar. 2009 - Total, operator of the OML 130 block, started production from its Akpo deepwater development offshore Nigeria. With proved and probable reserves estimated at 620 MMb of condensate and more than 1 Tcf of gas, Akpo is being developed through 44 subsea wells tied to the Akpo FPSO.
