The US Energy Information Administration describes API gravity as the “measure of specific gravity of crude oil or condensate in degrees. An arbitrary scale expressing the gravity or density of liquid petroleum products.” The following formula is used to calculate API gravity and calibrate the resu...
Crude Oil Viscosity vs. 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. The figure is based on information from more than 120 crude oil assays from BP, ExxonMobile and Statoil (2008 - 2017). The...
Reservoir fluid properties such as crude oil viscosity, oil formation volume factor, bubble point pressure, solution gas oil ratio, gas formation volume factor, isothermal compressibility and crude oil density are very important in reservoir engineering computations. An accurate description of reservoir fl...
(API) unit is commonly used to express the gravity or density of crude oil orpetroleum products. The API unit is a derivative of the conventional specific gravity at a given temperature. While specific gravity decreases with temperature, API gravity increases. The API scale is expressed in ...
Crude oil dehydration and desalting system with a higher gravity than 10 degrees API in mixing pipelinesA method for dehydrating and desalting an oil-in-water emulsion includes the steps of: injecting a demulsifier into the flow to destabilize the emulsion; injecting water to promote desalting; ...
