Madoes

Location and Geographical Context

The Madoes field is situated within a 35km area that includes several other fields, all part of the ETAP development. It is located around 19km south-west of the Central Processing Facility (CPF).

Field Characteristics

• The Madoes field is a subsea cluster that is tied back to the CPF through a 10-inch pipeline.
• It is characterized as a pressurized Eocene reservoir.

Development and Production

• The Madoes field began production in 2002, along with the Mirren field, as part of the ETAP expansion.
• The field is developed as a subsea tie-back to the CPF, which is shared among the various fields within the ETAP project.

Production Facilities

• The CPF, located over the Marnock field, serves as the central hub for processing and drilling operations for all the fields in the ETAP project, including Madoes.
• The CPF consists of a Processing, Drilling and Riser (PDR) platform and a Quarters and Utilities (QU) platform, linked by two bridges. This design separates the production risers and wellheads from the accommodation facilities.

Production Capacity and Reserves

• While specific reserves for the Madoes field alone are not detailed, the combined reserves for the ETAP project are estimated to be around 490 million barrels of oil equivalent, along with significant natural gas and condensate reserves.
• The CPF has the capacity to handle up to 120,000 barrels per day (bpd) of oil and approximately 440 million standard cubic feet (Mscf) per day of gas.

Operational and Investment Context

• The ETAP project, including the Madoes field, is undergoing a $1 billion investment program aimed at upgrading operations until the 2030s.
• BP operates the Madoes field as part of its responsibilities within the ETAP project, which also includes other fields such as Marnock, Mungo, Monan, Machar, Mirren, and others.

Safety and Environmental Considerations

• While specific environmental and safety details for the Madoes field are not provided, the ETAP project as a whole adheres to stringent safety and environmental standards. The project's design and operations are intended to minimize environmental impact and ensure safe working conditions.

In summary, the Madoes oil project is an integral part of the ETAP development, leveraging shared infrastructure and operational efficiencies to extract oil from a pressurized Eocene reservoir in the Central North Sea.
