How Is API Measured?

What is API oil?

The API designation in motor oil stands for the American Petroleum Institute.

The API is the largest oil and gas industry trade organization.

API’s outreach covers not only the oil and gas industry, but also any industry that has an impact on the petroleum interests..

What is an API report?

The American Petroleum Institute (API) and the U.S. Energy Information Administration (EIA) both provide weekly crude oil inventory reports. Oil inventory reports are indicators of the supply and demand for oil which impacts oil prices. The API is a trade association whereas the EIA is a governmental agency.

How do you calculate API?

Add 131.5 to the API gravity. The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured.

What is API gravity and how is it calculated?

API gravity is gradated in degrees on a hydrometer instrument and was designed so that most values would fall between 10° and 70° API gravity. The arbitrary formula used to obtain this effect is: API gravity = (141.5/SG at 60°F) – 131.5, where SG is the specific gravity of the fluid.

What is API gravity used for?

API gravity is short for American Petroleum Institute gravity, an inverse measure that is used to determine the weight of petroleum liquids in comparison to water.

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 unit?

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.

Is higher API oil better?

A crude oil will typically have an API between 15 and 45 degrees. Higher API indicates a lighter (lower density) crude. Lower API indicates a heavier (more dense) crude. Generally, lighter (high API) crudes are more valuable because they yield more high-value light products when run through a refinery.

What is API gravity of oil?

From 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.

Which country has best quality oil?

The 10 Most Influential Oil CountriesSaudi Arabia. As the world’s leading oil exporter, Saudi Arabia shipped 7.5 million barrels per day in 2016, according to data published by the Organization of Petroleum Exporting Countries (OPEC). … Russia. … Iraq. … Canada. … United Arab Emirates. … Kuwait. … Iran. … Venezuela.More items…•

What is API gravity of diesel?

The API gravity at 60°F (15.6°C) for No. 2 diesel fuel is between 30 and 42. The specific gravity, at 60/60°F, and the density, at 15.6°C, are between 0.88 and 0.82. (See Chapter 4 – Diesel Fuel Refining and Chemistry for an explanation of fuel blending, density, and API gravity.)

Why is light crude oil more expensive?

It generally has a low wax content. Light crude oil receives a higher price than heavy crude oil on commodity markets because it produces a higher percentage of gasoline and diesel fuel when converted into products by an oil refinery.
