Exploration giants Statoil have called to tender a new type of drilling rig, which they claim will improve efficiency of extraction by 20%. The new category J rigs will operate at water depths from 70 to 150 metres and drill wells down to 10,000 meters. It is a tailor-made rig for operations in harsh environment on both surface- and subsea wells on the Norwegian Continental Shelf.
Improving efficiency of drilling could be important to maximising the potential of the NCS say the Norwegian firm. Øystein Arvid Håland, head of drilling at Statoil said: “The key to maintain today’s production level on the NCS towards 2020 is improved recovery from existing fields and fast and effective development of new fields. We need to drill more wells to deliver on our production ambitions.”
The rig design is currently being developed in collaboration with various industry players such as hull designers, topside suppliers, construction yards and drilling contractors.
