The portion of heavy oil having an API gravity of less than 10°. Extra-Heavy oil Natural bitumen: Also known as "oil sands," bitumen shares the attributes of heavy oil but is even more dense and Transporting heavy crude often requires the addition of diluting agents, particularly in pipeline transport. These diluents are referred to as Heavy Oil Drag Reducing Agents or DRAs. Most pipelines were initially designed for light crude and thus cannot accommodate heavy crude unless it is modified. Often times, heavy and light crude are mixed Heavy crude oil evaporates slowly and contains material that will be used to make heavy products like asphalt. The standard unit of measurement is API Gravity. Sweetness of Crude Oil. You’ve probably heard people referencing “sweet” and “sour” oil. What makes a particular crude sweet or sour is the amount of sulfur it contains. Sweet crude has very low levels of sulfur, well under 1% The transportation of heavy and extra-heavy crude oils from the head-well to the refinery is becoming important since their production is currently rising all over the world. Such oils are characterized by a low API gravity (< 20) and high viscosity (> 10 3 cP at 298.15 K) that render difficult oil flow through pipelines. Conventional

equivalent to 50-100% of worldwide conventional oil reserves 5 to 10 times (?) the ultra-deep offshore potential reserves mainly (80%) in extra heavy oil, tar sands and bitumens mainly (80%) in North and South America less than 1% produced or under active development 310 260 Heavy Oil Reserves On the other hand, heavy crude oil or extra heavy crude oil is any type of crude oil which does not flow easily. It is referred to as “heavy” because its density or specific gravity is higher than that of light crude oil. Heavy crude oil has been defined as any liquid petroleum with an API gravity less than 20°. Extra heavy oil is defined Heavy crude can’t be produced, transported, and refined by conventional methods because it has high concentrations of sulfur and several metals, particularly nickel and vanadium. Heavy crude has density approaching, or even exceeding, that of water. Heavy crude oil is also known as “tar sands” because of its high bitumen content. 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 10° °API. Bitumen is the heaviest, thickest form of petroleum.

oil and not a bitumen; that is, a crude oil of less than 10° API is extra-heavy oil, regardless of the viscosity. Page 3. Prospects for heavy crude oil development 29 .
9 Sep 2016 Mixing heavy oil with light oil as well as ultrasound treatment are viable solutions to this problem. In this study, extra heavy crude oil samples were
World's energy challenges would be greatly improved upon if half of the world's heavy oil and extra heavy oil could be made to ow in pipelines. Viscosity Thus, in the near future, refineries will be obliged to replace light crudes by heavy /extra-heavy crude oils as feedstock. But, what is the real problem of this change 3 Jul 2019 Venezuelan state-owned energy company Petroleos de Venezuela (PDVSA) will begin blending light and extra heavy crude oil for export to 20 Sep 2017 Therefore, heavy crude oil is generally sold at a discount to light crude oil to account for the extra operating costs and larger investments made
16 Sep 2015 Therefore, isolate AS5 was used for heavy crude oil recovery additional 16 % extra heavy oil recovery after 5 days incubation at 40 °C. There
Production of crude from extra-heavy oil and bitumen was. 1.4 Mbbl/d in 2003 ( 1.8% of the world oil production), split approximately between Canada (2/3) and 14 Feb 2017 Biotransformation of heavy crude oil to light aliphatic and aromatic The most abundant compound in the extra recovered crude oil was 9 Sep 2016 Mixing heavy oil with light oil as well as ultrasound treatment are viable solutions to this problem. In this study, extra heavy crude oil samples were 10 Sep 2019 Ample global supply of light sweet crude oil doesn't necessarily bode price for its Arab Extra Light crude and Arab Heavy crude bound for The proposed model is applied to heavy and extra heavy crude oils in the presence of nanoparticles, considering the effects of nanoparticles concentration and
