What is the API of heavy crude oil?

A medium crude is in the 25-35 API range, and a heavy crude is in the 15-25 API range. Anything below 15 API would be considered an extra-heavy crude.

How do I convert API to PPG?

The formula for API gravity is API = (141.5/SG) -131.5 where SG is the specific gravity of the petroleum liquid being measured. For example, for an API gravity of 50, add 131.5 to obtain 181.5. Divide 141.5 by (131.5 + API gravity) to obtain the specific gravity of the oil.

What does API mean in oil and gas?

American Petroleum Institute
The API (American Petroleum Institute) number is a unique number assigned to every oil and gas well. It is used by agencies to identify and track oil and gas wells.

What API is light oil?

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/m3) and 42° API (816 kg/m3), while it defines light crude oil for non-U.S. oil as being between 32° API (865 kg/m3) and 42° API (816 kg/m3).

Why API gravity is 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 of diesel fuel?

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.

How many API standards are there?

In its first 100 years, API has developed more than 700 standards to enhance operational safety, environmental protection and sustainability across the industry, especially through these standards being adopted globally.

What is the difference between light and heavy crude oil?

The higher the number, the lighter the oil; any liquid with an API gravity higher than 10 is lighter than water. Crude oil with an API gravity less than 30 is considered “heavy”, and oil with an API gravity greater than 30 is “light”. Most grades have an API gravity between 10 and 70.
