Sentence examples for api gravity from inspiring English sources
noun
A specific gravity scale measuring the relative density of various petroleum liquids, expressed in degrees.
Extra-heavy oils are heavy crude oil with API gravity <10° API.
The measured API gravity and viscosity of the oil were 32.84° API and 8.54 cP at 20 °C, respectively.
On the basis of their API gravity, crude oils can be classified as heavy, medium, and light as follows: Heavy: 10 20° API gravity Medium: 20 25° API gravity Light: above 25° API gravity Crude oil also is categorized as "sweet" or "sour" depending on the level of sulfur, which occurs either as elemental sulfur or in compounds such as hydrogen sulfide.
The petroleum industry, however, uses the American Petroleum Institute (API) gravity scale, in which pure water has been arbitrarily assigned an API gravity of 10°.
API gravity of heavy crude oil is 21.27°, so it can be classified as heavy crude oil according to API convention.
The widely used American Petroleum Institute (API) gravity scale is based on pure water, with an arbitrarily assigned API gravity of 10°.
Heavy oil and tar sand, crude oils below 20° on the American Petroleum Institute (API) gravity scale that require mining or thermal recovery.
Tar sands, which are less than 10° API gravity and contain immobile bitumen, will not flow into a well bore even under thermal stimulation and thus require mining.
Oil API gravity (American Petroleum Institute).
