OSLO, Norway -- Petroleum Safety Authority Norway has authorized two drilling programs on the Norwegian shelf involving facilities owned and operated by North Atlantic Norway.

A/S Norske Shell has consent to use theWest Navigator vessel for drilling and well operations on Ormen Lange in the Norwegian Sea. The program, due to start this month, involves work on subsea template C, drilling of three production wells and drilling of a pilot well.

Statoil has permission to use the semisubmersible West Phoenix for drilling and well operations on Troll in the North Sea. Here the campaign involves permanent plugback and abandonment of wells on the Troll Oseberg Gas Injection (TOGI) subsea facility, and plugback and/or drilling and completion on production licenses 054 and 085 (Troll Olje), both of which Statoil operates.

The TOGI activity takes in wells 31/5-B-2 H, 31/5-B-3 H, 31/5-B-4 H, 31/5-B-5 H, and 31/5-B-6 H. Killing and temporary plugback of the wells, as well as pulling the christmas trees, will be performed via light well intervention.

Under the back-up,West Phoenix will drill well J-22 H on Troll Olje in well J-22 H.

Statoil’s program should take between six and eight months to complete.
