Anyala-Madu

Anyala-Madu Oil and Gas Field Profile

Location and Geology

The Anyala-Madu oil and gas field is located offshore in the central Niger Delta, Nigeria. Specifically, it is situated in the shallow waters of OML 83 and OML 85, approximately 30 to 40 kilometers offshore, where water depths range from 15 to 50 meters.

Field Composition

The Anyala-Madu project encompasses two main fields:

• Anyala Field: Located in OML 83, it includes three hydrocarbon compartments: Anyala West, Anyala Central, and Anyala East.
• Madu Field: Located in OML 85, it is developed in conjunction with the Anyala field as part of the Anyala-Madu project.

Operators and Ownership

The field is operated by FIRST Exploration & Petroleum Development (FIRST E&P), which holds a 40% stake. The Nigerian National Petroleum Corporation (NNPC) holds the remaining 60% stake.

Discovery and Development

• Discovery Year: The fields were discovered in 1972, but the development was initiated much later.
• Final Investment Decision (FID): Although the exact FID year is not specified, the project saw significant development milestones in recent years.
• Production Start: Oil production from the Anyala West field began in November 2020.

Reserves and Production

• Reserves: The combined reserves of the Anyala and Madu fields are estimated to be around 193 million barrels of oil and 0.637 trillion cubic feet (Tcf) of gas.
  • Crude oil reserves: Approximately 170-193 million barrels.
  • Gas reserves: Approximately 18.037 billion cubic meters (or 637 Bcf).
• Production: The peak production is estimated to be around 60,000 barrels of oil per day. The field currently accounts for about 2% of Nigeria's daily oil output.
  • Production design capacity: 18.24 million barrels of crude oil and condensate per year, and 1,219.6 million cubic meters of gas per year.

Infrastructure and Facilities

• Production Platform: The fields are being developed using an unmanned conductor-supported platform (CSP).
• FPSO: The Abigail-Joseph Floating Production Storage and Offloading (FPSO) unit is used to process the production. It is a 274-meter long converted Suezmax trading tanker with a storage capacity of 700,000 barrels, a processing capacity of 60,000 barrels of oil per day, 25,000 stock tank barrels of water per day, and 39 million standard cubic feet per day of gas.

Development Phases

• Phase 1: This phase involves the drilling of seven development wells in the Anyala West field. The objective is to develop 142 million barrels of oil and 98 billion standard cubic feet of gas from the fields.

Economic and Operational Aspects

• Investment: The total investment for the development of the fields is approximately $724 million, with Schlumberger acting as the technical service provider and financier.
• Production Life: Production is expected to continue until the field reaches its economic limit in 2068.
• Gas Monetization: The project includes plans for gas monetization, with gas delivered through the Nigerian Gas Company to various power distribution companies and independent power plants.

Environmental and Regulatory Considerations

• The project is subject to the regulations of the Petroleum Industry Act in Nigeria, which influences the fiscal and regulatory framework of the project.
