Prood continuing to fall. A real question here with the over supply under surveillance this morning, earnings from the oil giants crossing this hour. Exxon shares our lower with the plans for major expansion projects, Chevron rising after posting strong results, joining us now, Goldman Sachs's head of oil research down Stroy van Dan. Thank you so much for being here. What a year on all the commodity fronts. I'm just wondering with the oil giants, what this tells you about the path of production in the months and years to come.
