Twelve crude oils with 30 Jul 2019 These companies use the specific gravities as well as boiling points to the Specific Gravity, and our API Gravity for our particular crude oil Gravities are determined at 60 °F (15.56 °C), or converted to values at 60 °F, by means of Adjunct to D1250 Guide for Petroleum Measurement Tables (API
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.

From the phase diagram, following the pressure reduction path as indicated by the 2, Crude oil gravity (API), The specific gravity of the solution gas (γg); oil 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
13 Jun 2014 These rates are valid for oils with API gravities ranging from 6.5 to 9.5, in order to accurately predict the viscosity of undersaturated extra-heavy
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 °API to 22.3 °API (870 to 920 kg/m³) Heavy crude oil: API gravity from 22.3 °API to 10 °API (920 to 1000 kg/m³) Extra-heavy crude oil: API gravity below 10 °API (higher than 1000 kg/m³) 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. Estimate API Gravity at 60° F: 1) Usually, your API gravity reading will be at a temperature other than 60°F. To convert an API gravity reading to 60°F, we usually use ASTM Table 5B. The left and right margins of the table are annotated with the temperature. API gravity. API gravity is a commonly used index of the density of a crude oil or refined products.API stands for the American Petroleum Institute, which is the industry organization that created this measure.. Calculation of API gravity. API is calculated from a hydrocarbon's specific gravity using this formula:. API = (141.5/Specific Gravity) - 131.5 The API of crude oils varies typically between 10 and 50, with most crude oils falling in the range of 20-45. Using 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. Specific gravities of the components can be averaged State-level data show the difference in crude oil API gravity in different parts of the country. For example, oil produced in Texas has a relatively broad distribution of API gravities, with most production ranging from 30–50 degrees API. Oil produced in North Dakota tends to be light (less dense). About 90% of North Dakota’s oil production has an API gravity of 40.1–50.0 degrees. California’s oil is mostly heavy (more dense), and more than 90% has an API gravity of less than 30 degrees. The highest gravity oil to be treated is 41°API gravity oil in the Devonian sandstone in Alberta, Canada. The lowest gravity oil to be treated is 16°API gravity. This has occurred in two locations, the Sparky sandstone in Alberta, Canada and the Upper Topanga Sandstone (Miocene) offshore California. All three reservoirs have shown good waterflood response. Some of the reservoir parameters are shown in
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. API Gravity can be calculated as: °API = (141.5 / SG) - 131.5 (1) where °API = Degrees API Gravity . SG = Specific Gravity (at 60 o F) Specific gravity can be calculated from API gravity:

The specific gravity table published by the American Petroleum Institute (API) is a tool for determining the relative density of various types of oil. While it has no units of measurement, an oil's rating is expressed as API degrees. The scale is inversely related to the density of water. Any oil with an API score under 10 degrees sinks in water. -No Data Reported; --= Not Applicable; NA = Not Available; W = Withheld to avoid disclosure of individual company data. Notes: Values shown for the current month are preliminary. Values shown for the previous month may be revised to account for late submissions and corrections. API gravity = (141.5/Specific Gravity) – 131.5 Though API values do not have units, they are often referred to as degrees. So the API gravity of West Texas Intermediate is said to be 39.6 degrees. API gravity moves inversely to density, which means the denser an oil is, the lower its API gravity will be. 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 gravity of 40 – 45 generate the highest market prices. Any oils with API gravity of 45 or over have shorter molecular chains which are less desirable to refineries.
