Crude oil viscosity api
API gravity is one of the key characteristics of crude oil that, along with other characteristics such as sulfur content, is used by refiners when evaluating different crude streams for processing into petroleum products. API Gravity of the Crude Oil, °API In the oil and gas industry, crude oils are characterized by the API gravity (American Petroleum Institute gravity) of the oil. The units of the API gravity are degrees, °API (read as degrees API). Oil viscosity vs density (API) The following are useful to estimate oil viscosity if the API (i.e. density) is known. For 25° API oil expect an oil viscosity of about 10 cp and for 30° API about 6 cp. Crude oil viscosity as a function of API gravity [5]. With the dead oil viscosity at atmospheric pressure and reservoir temperature (either measured or obtained from Figure 1.9 ), the effect of solution gas can be estimated with the aid of Figure 1.10 [ 6 ]. The most common definition of heavy crude oil is crude oil with API gravity less than 20, according to the International Energy Agency (IEA) and US geological survey (USGS). Viscosity and density play very important roles in oil production, transportation through pipelines, and oil recovery processes. the viscosity of heavy crude oil as a function of temperature, and as a function of a simple correlating parameter that can be used for heavy-oil characterization.
Dead or gas-free oil viscosity is determined as a function of crude oil API gravity and temperature. The viscosity of the gas saturated oil is found as a function of dead oil viscosity and solution gas-oil ratio (GOR) .

Between 30° API and 11° API, the viscosity becomes more important, until in some cases it is impossible to process very low gravity crudes without a diluent to reduce the viscosity. The use of a diluent is not unusual for crude oil below 14° API.
Dead or gas-free oil viscosity is determined as a function of crude oil API gravity and temperature. The viscosity of the gas saturated oil is found as a function of dead oil viscosity and solution gas-oil ratio (GOR) . 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. Crude oil viscosity as function of gravity. Viscosity at 20°C/68°F and 50°C/122°F for more than 120 crudes is shown as function of specific gravity@15°C/60°F. Sponsored Links. The figure is based on information from more than 120 crude oil assays from BP, ExxonMobile and Statoil (2008 - 2017). Between 30° API and 11° API, the viscosity becomes more important, until in some cases it is impossible to process very low gravity crudes without a diluent to reduce the viscosity. The use of a diluent is not unusual for crude oil below 14° API.

Crude Oil @ 35 F with SG .85 (API 34.971) By the equation it has a viscosity of 241 cP, but the info i looked up gave a viscosity of 9.2 cP. Just wondering if you, or anyone could explain this (giant) difference.
Definitions. Petroleum Types: Light oil, also called conventional oil, has an API gravity of at least 22° and a viscosity less than 100 centipoise ( 18 Mar 2019 Tar sands (also called bituminous sands and oil sands) have, the resource volumes of heavy oil and bitumen, viscosity of the oil should be generally corresponding to a specific gravity of less than 10° API at 60°F (16°C).
The American Petroleum Institute (API) defined the API gravity (degrees API) to quantify the quality of petroleum products and crude oils. The API gravity is defined as Crude Oils API = 10 – 50, crude oils can generally be classified according to API as shown The definition of specific gravity for gases is somewhat different. 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°,
