"Our main objective is to reach at least four million barrels a day of production capacity by 2020 and most of this extra output will be from heavy oil,'' Farouk al-Zanki, chairman of Kuwait Oil Co., said in an interview in Abu Dhabi with Bloomberg News. "We expect heavy oil production to reach 900,000 barrels a day at full capacity.''
Heavy, or sour, oil is higher in sulfur and less viscous than sweet crude, making it more expensive for refiners to process into marketable products such as gasoil, naphtha, and gasoline.
A little bit extra, may be a little too late.
