WebHeavy Oil or Extra Heavy Oil is any type of crude oil that does not flow easily. It is called “heavy” because its density or specific weight is higher than that of light crude oil. While … In 2010, the World Energy Council defined extra heavy oil as crude oil having a gravity of less than 10° and a reservoir viscosity of more than 10,000 centipoises. When reservoir viscosity measurements are not available, extra-heavy oil is considered by the WEC to have a lower limit of 4° API. See more 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 See more Heavy crude oil is closely related to natural bitumen from oil sands. Petroleum geologists categorize bitumen from oil sands as ‘extra-heavy oil’ due to its density of less than … See more Production of heavy oil is becoming more common in many countries, with 2008 production led by Canada and Venezuela. Methods for … See more Most geologists agree that crude becomes ‘heavy’ as a result of biodegradation, in which lighter oils are preferentially consumed by bacterial activity in the reservoir, leaving … See more Heavy crude oils provide an interesting situation for the economics of petroleum development. The resources of heavy oil in the world are … See more With current production and transportation methods, heavy crudes have a more severe environmental impact than light ones. With more difficult production comes the employment of a variety of enhanced oil recovery techniques, including steam flooding and tighter … See more Heavy oil is asphaltic and contains asphaltenes and resins. It is "heavy" (dense and viscous) due to the high ratio of aromatics and naphthenes to linear alkanes and high levels of … See more
