Offshore staff

KUALA LUMPUR, Malaysia – Hibiscus Petroleum has issued an update on its development plans for the Marigold and Sunflower oil fields in the UK central North Sea.

Late last year,Anasuria Hibiscus UK entered an agreement to acquire a 50% interest from Caldera in blocks 15/13a and 15/13b, containing the two discoveries, for $37.5 million.

The location is 250 km (155 mi) northeast of Aberdeen in 140 m (459 ft) water depth. Consultant AGR TRACS International estimates contingent (2C) oil resources across the blocks at 60 MMbbl.

Since completing the transaction, Anasuria Hibiscus UK has established a dedicated project team in Kuala Lumpur to undertake subsurface field development and engineering studies.

Petrofac Facilities Management is providing support for the concept select phase which is targeted to be completed in mid-2019. Concepts under review include a fixed platform, floating solutions, and a tieback to nearby infrastructure.

Elsewhere in the central UK sector, Anasuria Hibiscus UK is a partner in the Ithaca Energy-operated Cook field water injection project.

This will involve drilling a water injector well into the field in mid-year to raise its reservoir pressure, leading to increased production and enhanced oil recovery.

An associated subsea pipeline is due to be installed in the second half of the year linking the well to the Hibiscus-operated Anasuria FPSO.

Offshore North Sabah, Malaysia, Petronas and Hibiscus have budgeted RM142.6 million ($35 million) for the St Joseph field infill drilling development.

This entails drilling of three producer wells from a triple splitter wellhead on the St Joseph Jacket-A platform, with associated topsides facilities modifications (to the flowlines, wellhead control panel, chemical pump system and chokes).

Drilling is slated to start in April with oil flow beginning in June. The program should increase production at peak by around 2,600 b/d.
