KUALA LUMPUR, MalaysiaHibiscus Petroleum plans to develop the Marigold and Sunflower oil discoveries in the UK central North Sea via flexible flowlines and umbilicals connected to an FPSO.

The project is set to proceed in two phases in order to mitigate subsurface uncertainties and minimize capex to first oil.

Under Phase 1, three wells will likely be drilled on Marigold and tied back to the FPSO via a production manifold.

Additional wells on Marigold, Sunflower, and the recently acquired Crown field could be developed in the second phase.

Recently the company brought onstream a newly drilled side track from the GUA-P1 well on the Guillemot oil and gas field in the Anasuria cluster in the same region.

The final part of the project entailed installing a gas-lift jumper to enhance production.

Hibiscus believes the new data, obtained from this well, will allow it to revise its geological model of Guillemot following a more detailed subsurface study.
