Petroleum geologists categorize bitumen from oil sands as ‘extra-heavy oil’ due to its density of less than 10° API. Bitumen is the heaviest, thickest form of petroleum. According to the U.S. Geological Survey, bitumen is further distinguished as … Ver mais Heavy crude oil (or extra heavy crude oil) is highly-viscous oil that cannot easily flow from production wells under normal reservoir conditions. It is referred to as "heavy" because its density Ver mais Heavy crude oils provide an interesting situation for the economics of petroleum development. The resources of heavy oil in the world are more than twice those of conventional light crude oil. In October 2009, the United States Geological Survey updated the Ver mais Most geologists agree that crude becomes ‘heavy’ as a result of biodegradation, in which lighter oils are preferentially consumed by … Ver mais Heavy oil is asphaltic and contains asphaltenes and resins. It is "heavy" (dense and viscous) due to the high ratio of aromatics Ver mais Production of heavy oil is becoming more common in many countries, with 2008 production led by Canada and Venezuela. Methods for extraction include Cold heavy oil production with sand Ver mais With current production and transportation methods, heavy crudes have a more severe environmental impact than light ones.
