8 Feb 2015 Any crude oil with API gravity of over 31.1 degrees falls into the light crude oil category. Medium crude oil. Oils with API gravity falling between 20 Feb 2020 Crude oils are classified from light to heavy based on the API gravity scale and are classified as sweet if they contain less than 0.42%sulphur ( Low API gravity, high amounts of impurities, and high viscosity are the major Generally, today, conventional oil includes light crude oil with natural gas and its API Gravity of some standard crudes. • West Texas Intermediate. 40. • Canadian Syn-crude. 33. • Arab Light. 32. • Alaska NS Crude. 29. • Arab Heavy. 27.
24 Nov 2017 The weighted average API gravity of EU crude imports in 2016 was 35.2°, according to Eurostat. Refinery inputs look similar: the current average
Light oil also made up more than half of the oil produced in 2015. 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. Calculation of API gravity. API is calculated from a hydrocarbon's specific gravity using this formula: API = (141.5/Specific Gravity) - 131.5. API gravity of crude oil grades. 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. Crude oil with API gravity less than 10° is referred to as extra heavy oil or bitumen. Bitumen derived from oil sands deposits in Alberta, Canada, has an API gravity of around 8°. It can be diluted with lighter hydrocarbons to produce diluted bitumen, which has an API gravity of less than 22.3°, 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. As the “weight” of an oil is the largest determinant of its market value, API gravity is exceptionally important. The API values for each “weight” are as follows: Light – API > 31.1; Medium – API between 22.3 and 31.1; Heavy – API < 22.3; Extra Heavy – API < 10.0 . These are only rough valuations as the exact demarcation in API gravity between light and heavy oil changes depending on the region from which oil came. The fluctuation as to what constitutes light crude in a given Extra heavy oil. Also referred to as bitumen, extra heavy crude oils have API gravity of below 10.0 degrees. While these are accurate classifications it’s important to note that exact differentiations between light, medium, heavy and extra heavy will vary depending on the region of origin. At the end of the day,
Heavy vs Light Crude Oil. American Petroleum Institute (API) gravity is the measure of the weight of crude oil. API gravity is a measure of the weight of a crude oil in relation to water. “If an oil’s API Gravity is greater than 10, it is lighter than water and will float on it.
19 Apr 2017 API gravity is one of the key characteristics of crude oil that, along the API gravity, the lower the density of the petroleum liquid, so light oils API Gravity is the oil industry standard used to determine and classify the density of oil. Density is an integral part of determining the value of oil, where light oils how many barrels of crude can be extracted from a metric ton of a given oil. Light crude oil: API gravity higher than 31.1 °API (less than 870 kg/m³); Medium crude oil: API gravity from 31.1 °API to 22.3 °API (870 to 920 kg/m³); Heavy crude This measurement reflects how light or heavy a crude oil is compared to water. If an oil's API Gravity is greater than 10, it is lighter than water and will float on it.
