I'm not sure how the N Sea is going to pan out in the future - there has been a significant change there and would need a big upturn in exploration to drive a higher demand for helicopters and pilots. The oil companies are shying away from deep sea exploration for the time being
I notice that the price of photo-voltaic cells has been falling consistently for decades and is predicted to fall further for the foreseeable future. Elon Musk and Samsung (probably others) are both I believe rapidly increasing the production rate for solar cells and have been for some time. They are made from sand and the price depends on the efficiency of production which in turn depends on the production volume. Volumes are rising rapidly.

Various countries have set dates for the end of petroleum powered car sales.
I am sorry to say for North Sea people that I do not see much prospect of an Oil Price recovery anytime soon.
I am however not an oil industry expert so what do I know?
Good luck to you all.
