Recalculation of density of oil for different temperature and pressure values. Formulas are taken from Russia's GOST R 8.610-2004. Decade, Year-0, Year-1, Year-2, Year-3, Year-4, Year-5, Year-6, Year-7, Year-8, Year-9. 1980's, 32.46, 32.33, 32.22, 31.93, 32.14. 1990's, 31.86, 31.64, 31.32 This mathematic calculation is done using Volume Correction Factors (VCF). Each different type of petroleum product group has a different VCF. The historical
Oil gravity is usually 40° API or higher and increases during production after the bubble Calculate the height of the oil and the height of the water in the tank.
Online calculator. Recalculation of density of oil for different temperature and pressure values. Formulas are taken from Russia's GOST R 8.610-2004. "State system for ensuring the uniformity of measurements. Density of oil. The tables for recalculation" standard This calculator works on an iterative method to calculate, in each step, the amount of diluent that would be required to reach a target gravity and then determine any discrepancies caused by shrinkage. Further iterations can then be used to get closer to the target gravity. The local gravity is dependent on several factors such as latitude, height above sea-level, local geological density, etc… Refer to your national geological survey data for your location or use this local gravity calculator to determine a close approximation. The default value is set to 9.80665 ms-2 which is standard gravity. Hydrostatic Pressure Do not use calculations for anything where loss of life, money, property, etc could result from inaccurate calculations. Oil conversion substances You can use this converter to convert betwen units of volume and weight (for example, barrels, liters, kilograms and pounds) for crude oil, diesel fuel oils and gas oils. NB: Specific Gravity is always relative to pure water. Calculating Pressure Gradient: Most of the time you will not be given a fluid gradient or an average specific gravity, you will need to calculate it. First calculate your average specific gravity: Average SG = SG of water x Water Cut + SG of oil x (1-Water Cut) Then calculate your Gradient: This example illustrates the steps necessary to calculate oil viscosity requiring correlations for dead oil viscosity, bubblepoint viscosity, undersaturated viscosity, and bubblepoint pressure/solution GOR. Errors in individual correlations can compound and propagate through to the resulting answer. oil specific gravity μ o = oil viscosity
Liquids lighter than water, such as oil, have API gravities numerically greater than 10. On the basis of their API gravity, crude oils can be classified…
Definition of API Gravity of water provided by WikiPedia: 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. API Gravity to Specific Gravity and Specific Gravity Of Oil Calculator Specific gravity (sp gr) measures the ratio of density of the substance to the density of water in a given temperature, (i.e., 4 o C). It is a dimensionless unit. 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. API Gravity can be calculated as:
22 Apr 2014 Changes in crude oil density and specific heat, or heat capacity, can be estimated from look up a number from a graph, and then proceed with the calculation. Figure 1A Crude Oil Specific Gravity vs Temperature (1).
D2501-14(2019) Standard Test Method for Calculation of Viscosity-Gravity Constant (VGC) of Petroleum Oils viscosity-gravity constant~ density~ hydrocarbon Liquids lighter than water, such as oil, have API gravities numerically greater than 10. On the basis of their API gravity, crude oils can be classified… For E&P TANK, Low Pressure Gas option: to get separator gas composition. Sales oil sample. •. •. •. API gravity measurement;. RVP measurement;. For E&P TANK It was identified the need of an accurate correlation for calculating viscosity of heavy crude oils. Thus, a new correlation is proposed, which was validated using In this video David explains what specific gravity means. He also shows how to calculate the value for specific gravity and use it to determine the percent Just use the density of oil instead of the density of water in the specific gravity formula.
Calculating API Gravity. To calculate API gravity, you need to know the fluid's specific gravity. Divide 141.5 by the fluid's specific gravity and subtract 131.5. If
The standard volume unit for crude oil measurement, the 42-gallon barrel ("bbl"), dates Oil density is sometimes expressed in terms of its specific gravity, but more often is given as API gravity. Conversion Table and Electronic Calculator.
Specific gravity of a liquid is the ratio of the density of the liquid at 60°F to the density of pure water. API gravity is related to the specific gravity by the following equation: The specific gravity of a gas is the ratio of the density of the gas to the density of air at standard conditions of temperature and pressure.

Corrected API @ 60 deg F . Corrected API Gravity for Temperature other than 60 deg F. This calculator works on an iterative method to calculate, in each step, the amount of diluent that would be required to reach a target gravity and then determine any discrepancies caused by shrinkage. Further iterations can then be used to get closer to the target gravity. API Gravity Input a number in any blank and press the "Calculate" button.
