Api crude oil measurement

API Gravity is the oil industry standard used to determine and classify the density of oil. the API has set is the method used for measuring the density of petroleum. how many barrels of crude can be extracted from a metric ton of a given oil. The density of crude oil and liquid hydrocarbons is usually reported in terms of (API) adopted the API gravity (°API) as a measure of the crude oil density. Viscosity Table – Measurement data. Crude oils - viscosity and °API. Typical values obtained from producer's data sheets. Oct 3, 2018 Chapter 18.2 addresses custody transfer of crude oil from lease tanks using alternative measurement methods. It can now include automatic

In crude measurement, the reference substance is pure water. If the crude oil had the same density as water, then the SG would be 1.0. The resulting value is expressed in degrees between 10 and 70. In this example, the formula result of “ (141.5/1.0) – 131.5” would be 10 degrees.

The American Petroleum Institute (API) is the only national trade association that represents all aspects of America’s oil and natural gas industry. Our more than 600 corporate members, from the largest major oil company to the smallest of independents, come from all segments of the industry. API Gravity is a measure of how heavy or light crude-oil is compared to water (density of crude oil / density of water). The API Gravity measurement is a positive number that is inversely correlated to crude-oil specific gravity (the lighter the crude-oil, the higher the API Gravity) API gravity express the gravity or density of crude oil and liquid petroleum products. API is devised jointly by the American Petroleum Institute and the NIST - National Institute of Standards and Technology. The measuring scale is calibrated in terms of degrees API. Definition of API Gravity of water provided by WikiPedia: 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.

Because density is a measure of weight per volume, API can be used to calculate how many barrels of crude can be extracted from a metric ton of a given oil. A metric ton of West Texas Intermediate, with an API of 39.6, will produce 7.6 barrels (at 42 gallons each). The calculation is: Barrels per metric ton = 1/[(141.5/(API + 131.5) x 0.159]
