If Greenland were to sell leases for petroleum exploration it would probably go to European oil companies. My first thought is Norway. But, the idea a Texas company decided to occupy Greenland is an outrageous injury to that country.
Denmark is phasing out it's petroleum industry. I believe Denmark will no longer produce oil for domestic use or for sale. The country has a conscience. They value the future of their children. To think Greenland would allow oil production is an outrage, insult, and injury.
