Offshore activities will return on 'dollars not dimes'. Once oil has set in at about $80, for some period of time (so oilers can make some $), and if there is confidence of higher prices for longer, then future investments in the offshore project space should be made.

I'm not an advocate of The Motley Fool tho the US version is a bit better. Good to read about Transocean to get a feel of the general offshore space... No green shoots yet... One article attached.
