2. API gravity - Wikipedia

   en.wikipedia.org/wiki/API_gravity

   Heavy crude oil has an API gravity below 22.3° (i.e., 920 to 1000 kg/m 3) Extra heavy oil has an API gravity below 10.0° (i.e., greater than 1000 kg/m 3) However, not all parties use the same grading. [9] The United States Geological Survey uses slightly different ranges. [10] Crude oil with API gravity less than 10° is referred to as extra ...

3. Light crude oil - Wikipedia

   en.wikipedia.org/wiki/Light_crude_oil

   The clear cut definition of light and heavy crude varies because the classification is based more on practical grounds than theoretical. The New York Mercantile Exchange (NYMEX) defines light crude oil for domestic U.S. oil as having an API gravity between 37° API (840 kg/m 3) and 42° API (816 kg/m 3), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m 3 ...

4. Heavy crude oil - Wikipedia

   en.wikipedia.org/wiki/Heavy_crude_oil

   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 Orinoco deposits (Venezuela) recoverable value to 513 billion barrels (8.16 × 10 10 m 3), [16] making this area one of the world's largest recoverable oil deposits. However ...

5. List of crude oil products - Wikipedia

   en.wikipedia.org/wiki/List_of_crude_oil_products

   The three most quoted oil products are North America 's West Texas Intermediate crude (WTI), North Sea Brent Crude, and the UAE Dubai Crude, and their pricing is used as a barometer for the entire petroleum industry, although, in total, there are 46 key oil exporting countries. Brent Crude is typically priced at about $2 over the WTI Spot price ...

6. Fuel oil - Wikipedia

   en.wikipedia.org/wiki/Fuel_oil

   An oil tanker taking on fuel, or "bunkering". Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating ...

7. SAE J300 - Wikipedia

   en.wikipedia.org/wiki/SAE_J300

   SAE J300. SAE J300 is a standard that defines the viscometric properties of mono- and multigrade engine oils, maintained by SAE International. [1] Key parameters for engine oil viscometrics are the oil's kinematic viscosity, its high temperature-high shear viscosity measured by the tapered bearing simulator, and low temperature properties ...
