At the time, producing from satellite wells a mere 5 km away was the limit of what could be practically achieved with direct hydraulic controls. Extending beyond 5 km with existing technology raised significant concerns related to making wells safe in an emergency, while the manufacture and installation of large lengths of bundled umbilicals was also technically challenging. At the same time, the water depth and hostile environment of the Magnus field made two-platform field development prohibitively expensive. The operator needed an alternative approach. As development of the solution progressed, so too did the operator's business case which came to rely on the use of the multiplexed electrohydraulic control system.
