WebApr 26, 2024 · Introduction. Heavy oil is defined as liquid petroleum of less than 20°API gravity or more than 200 cp viscosity at reservoir conditions. No explicit differentiation is … WebUsing API gravity, the conventional crude oils can be generally considered as light (°API>30), medium (30>°API>22), and heavy (°API<22). Note that the relationship between °API and specific gravity is not linear. Therefore, the °API gravity of crude blends cannot be calculated by linear averaging of the component °APIs.
Extra heavy oil has an API gravity below 10.0° (i.e., greater than 1000 kg/m 3) However, not all parties use the same grading. [5] The United States Geological Survey uses slightly different ranges. [6] Crude oil with API gravity less than 10° is referred to as extra heavy oil or bitumen. See more 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 … See more The formula to calculate API gravity from specific gravity (SG) is: $${\displaystyle {\text{API gravity}}={\frac {141.5}{\text{SG}}}-131.5}$$ Conversely, the specific gravity of petroleum liquids can be derived from their API gravity value as See more To derive the API gravity, the specific gravity (i.e., density relative to water) is first measured using either the hydrometer, detailed in ASTM D1298 or with the oscillating U-tube method … See more • Comments on API gravity adjustment scale • Instructions for using a glass hydrometer measured in API gravity See more In the oil industry, quantities of crude oil are often measured in metric tons. One can calculate the approximate number of barrels per metric ton for a given crude oil based on its API gravity: For example, a … See more There are advantages to field testing and on-board conversion of measured volumes to volume correction. This method is detailed in ASTM D287. See more Generally speaking, oil with an API gravity between 40 and 45° commands the highest prices.
