Indefatigable South West

Location and Geology

• The Indefatigable South West gas field is situated in block 49/23a of the UK Continental Shelf, in the Southern North Sea.
• The field is located in shallow water, with a water depth of approximately 96 feet.

Ownership and Operation

• The field is owned by Perenco Holdings and Viaro Energy.
• Perenco UK Limited is the operator of the field, and the company is primarily involved in crude petroleum production.

Production History

• The Indefatigable South West field was discovered as part of the broader Indefatigable gas field complex, which was initially discovered in 1966. However, the specific South West segment has its own production profile.
• Production from the Indefatigable South West field began after the initial development of the broader Indefatigable field. The peak production for the South West field was achieved in 1997.

Production and Reserves

• The field has recovered 99.67% of its total recoverable reserves as of the latest data. Based on economic assumptions, production is expected to continue until the field reaches its economic limit in 2027.
• The field has been a significant contributor to the UK's gas production, although specific current production rates are not provided in the available sources.

Infrastructure

• While detailed infrastructure specifics for the Indefatigable South West field alone are not extensively documented, it is part of the larger Indefatigable field infrastructure. The broader Indefatigable field includes several platforms, such as Juliet-D, Juliet-P, Kilo, Lima, Mike, and November, although these are primarily associated with the original Indefatigable field rather than the South West segment.

Decommissioning and Current Status

• The original Indefatigable field, operated by Shell and Esso, ceased production in 2005 and underwent decommissioning. However, the Indefatigable South West field, operated by Perenco, is still in production and is expected to continue until 2027.

Transportation and Processing

• Gas from the Indefatigable South West field is transported to the Bacton Gas Plant for processing, similar to the original Indefatigable field. This aligns with the broader infrastructure used in the Southern North Sea for gas production and processing.

In summary, the Indefatigable South West gas field is an active production field in the Southern North Sea, operated by Perenco UK Limited, with ownership shared between Perenco Holdings and Viaro Energy. It is expected to continue production until 2027 and is part of the larger gas production infrastructure in the UK Continental Shelf.
