How is oil API calculated?
The official formula used to derive the gravity of petroleum liquids from the specific gravity (SG), as follows:API gravity = 141.5/SG – 131.5.RD at 60oF = 141.5 / (API gravity + 131.5)Barrels of crude oil per metric ton = 1 / [141.5 / (API gravity + 131.5) x 0.159].
Does API gravity change with temperature?
API gravity increases with increasing temperature, while specific gravity decreases with increasing temperature. … This means that the volume of a petroleum liquid increases with increasing temperature, and that a density number always must be given with the measurement temperature.
Why is API gravity important?
The API Gravity of a product is very important in determining the characteristics of the petroleum product. To learn more about this property, let’s apply the AmSpecapproach. API Gravity, or The American Petroleum Institute gravity, is a measure of how light or heavy a petroleum liquid is compared to water.
What is the API gravity of crude oil?
API gravity is measured as the inverse of the density of a petroleum liquid relative to water. The higher the API gravity, the lower the density of the petroleum liquid, so light oils have high API gravities.
What is API unit?
1. n. [Formation Evaluation] The unit of radioactivity used for natural gamma ray logs. This unit is based on an artificially radioactive concrete block at the University of Houston, Texas, USA, that is defined to have a radioactivity of 200 American Petroleum Institute (API) units.
What is standard API?
The Standard API is a REST API between client apps and the EVRYTHNG Platform. It is used to create and manage projects, applications, products, thngs, actions, and more platform resources. This API Reference section of the Developer Hub contains sections for each module of the API.
What is API oil classification?
The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. … It specifies the viscosity grade required for your car’s engine.
How many types of crude oil are there?
fourThe four primary types of oil are: (1) The Very Light Oils / Light Distillates which include: Jet Fuel, Gasoline, Kerosene, Light Virgin Naphtha, Heavy Virgin Naphtha, Petroleum Ether, Petroleum Spirit, and Petroleum Naphtha.

What is the API of heavy oil?
Light oil is characterized by an API gravity of at least 22°, and extra-heavy oil has an API gravity of less than 10°. Natural bitumen, also known as oil sands, shares the characteristics of heavy oil but is even more dense and viscous – with a viscosity greater than 10,000 cP.
What is the highest quality crude oil?
Sulfur content and weight are the two qualities by which crude oil is typically judged. High-sulfur, heavy oils are the lowest quality and the least expensive on the global market. Low-sulfur, light oils bring the highest price because they are of the highest quality.
Who owns most of the oil in the world?
However, in 2019, five countries accounted for about half of the world’s total crude oil production.The top five crude oil producers and their percentage shares of world crude oil production in 2019 were.United States15%Russia13%Saudi Arabia12%Iraq6%Canada5%

What does API in oil mean?
American Petroleum Institute gravityFrom Wikipedia, the free encyclopedia. The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water: if its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks.
What does API SG mean?
American Petroleum InstituteCheck owner’s manual to assure appropriate service category and viscosity grade. With regards to “API SG,” The American Petroleum Institute (API) Says: Status: “Obsolete” Service: “For 1993 and older engines” Example of an SG label: XCEL XHD TURBO 5W-30.
