Heavy oil api classification
17 Feb 2014 When crude oil is classified based on its API gravity it is divided into one of the following four classifications: Light – Light crude oil has an API 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. FIND Crude's classification as either “light” or “heavy” depends on the oil's relative density, based on the American Petroleum Institute (API) Gravity. This measurement Classification according to the API degree: Light crude oil: API gravity higher than 31.1 °API (less than 870 kg/m³); Medium crude oil: API gravity from 31.1 16 Oct 2018 API gravity the samples were classified as light (API30), medium (API23) and heavy (API16) crude oils [25]. Note that, as expected [1], density 17 Feb 2011 The different types of crude oil are classified based on the American Petroleum Gravity (API) gravity and viscosity. The properties may vary in 8 Feb 2015 Barrels of crude oil per metric ton = 1 / [141.5 / (API gravity + 131.5) x 0.159]. API gravity classifications and grades. In general oils with API
The Basics of Crude Oil Classification. Liquid petroleum pumped from oil wells is called “crude” or "crude oil.". Composed predominantly of carbon, crude oil contains approximately 84 to 87 percent carbon and 11 to 13 percent hydrogen. Crude oil also contains varying amounts of oxygen, sulfur, nitrogen, and helium.
API Gravity- An arbitrary scale expressing the gravity or density of liquid measure for bulk quantities of crude oil, gasoline/diesel fuel, and other refined stocks. ISO Viscosity Grade System- A Classification for industrial lubricants based on Crude oil is classified as light, medium, or heavy according to its measured API gravity. Light crude oil has an Crude oil with low carbon, high hydrogen and high API (American Petroleum Institute) is rich in paraffins and produces large quantities of gasoline and light D287 - 12b(2019) · Standard Test Method for API Gravity of Crude Petroleum Particle Shape Classification of Oils Using a Direct Imaging Integrated Tester.
An API of 10 is equivalent to water, which means any oil with an API above 10 will float on water while any with an API below 10 will sink. The API gravity is used to classify oils as light, medium, heavy, or extra heavy. As the “weight” of an oil is the largest determinant of its market value, API gravity is exceptionally important.

API began licensing oils against the SN PLUS classification on May 1, 2018. As marketers consider developing oils that comply with the SN PLUS classification, they should keep the following points in mind: Marketers may identify oils that meet all of the requirements of the standards as meeting API SN with SN PLUS or API SN In the USA, the API oil classification system provides a simple designation for engine oils to ensure that the proper type of oil is selected for an engine. Oil classification systems have been also in place in the EU and Japan. Below is an overview of the four major crude oil classifications: Any crude oil with API gravity of over 31.1 degrees falls into the light crude oil category. Oils with API gravity falling between 22.3 and 31.1 degrees are classed as medium crude oils. Heavy crude oils have API gravity of under 22.3. SJ 1997 Gasoline Engine Service Category SJ was adopted in 1996 to describe engine oil first mandated in 1997. It is for use in service typical of gasoline engines in present and earlier passenger cars, vans, and light trucks operating under manufacturers recommended maintenance procedures. The current and previous API Service Categories are summarized in convenient charts. Vehicle owners should refer to their owner's manuals before consulting these charts. Oils may have more than one performance level. For automotive gasoline engines, the latest engine oil service category includes the performance properties of each earlier category.
Classification according to the API degree: Light crude oil: API gravity higher than 31.1 °API (less than 870 kg/m³); Medium crude oil: API gravity from 31.1
A common classification using the API density scale is: <10°API is super-heavy crude oil, and,. 10° to 20°API is extra-heavy crude. Dr George Stosur (US Crude oil is classified into five categories based on the measured density (API gravity). Crude (1) Density : Used in crude oil classification, weight and volume. 2 Jun 2015 Crude oil is classified as light or heavy oil based on different physical properties, such as molecular weight, viscosity, density, and API gravity. 4 Jun 2015 Viscosity increases with decreases in crude oil API gravity (assuming a constant Watson characterization factor) and decreases in temperature. 8 Oct 2019 Bitumen and heavy crude oil are characterized by high viscosity and low Bitumen, defined as an API Gravity less than 10 degrees, and heavy crude oil The component chemicals in crude oil are classified into paraffinic, Light Crude oil is liquid petroleum that has low density and that flows freely at room temperature. It has low viscosity, low specific gravity and high API gravity due 2 Dec 2009 Brent crude and WTI (West Texas Intermediate) are. uses references to “ Geographical Locations” in order to descriptively classify crude oils. If an oils “ API Gravity” is less than 10, it is heavier than water and will sinks.
In order of increasing molecular weight, they are volatile oil, black oil, and heavy oil. Heavy-oil reservoirs are of minor interest during pressure depletion because they typically yield only marginal amounts of oil because of their low dissolved-gas contents and high fluid viscosities.
