Scotland's First Minister Alex Salmond has said that "cooperation between companies" is key to success in the North Sea.
Speaking to Radio 4's Today Programme, he said: "There has to be cooperation, as there is now for example between the Norwegian and the UK sectors of the North Sea. In fact there are some fields that straddle both sectors.
"The key aspect here is to get cooperation between the companies.
"The point that Sir Ian Wood is making is a critical point - is to get that integration between companies, to share infrastructure so as you can enhance recovery. The sums we are talking about are absolutely massive."
David Cameron is expected to claim that only the UK Government has the financial muscle to boost oil production in the North Sea.
Is it a coincide the Cabinets of both the UK and Scottish governments are meeting in Aberdeenshire on the same day? Of course not.
