The density of formation water at reservoir conditions can be calculated in four steps. The salt content can be estimated from the formation resistivity, as measured from electric-log measurements. The only field datum necessary is the density at standard conditions, which can be obtained from the salt content by use of Fig.

When laboratory data or actual water samples are unavailable, the density of formation water at reservoir conditions can be estimated roughly (usually to within +/−10%) from correlations ( Figs.

Experimental verification of the computer predictions should be performed in cases in which any error could have significant impact. Alternatively, some modern multicomponent chemical equilibrium simulators accurately calculate the densities (and other physical properties) from the complete analysis of the waters within the temperature and pressure range of the thermodynamic database. Thus, water samples taken for providing input to these programs must have accurate densities determined experimentally.

However, process simulation software used in modern facility design uses the true density or specific gravity of the water to avoid significant cumulative errors, especially when working with low-gravity heavy oils or concentrated brines. Direct measurement for density of seawater is done by maintaining the collected water samples in controlled environmental conditions.In the past, density in metric units (g/cm 3) was considered equal to specific gravity therefore, for most engineering calculations, density and specific gravity were interchangeable in most of the older designs. Likewise, check the water density of samples having same salinity and different temperatures. All you need is enter the temperature (both in Celsius and Fahrenheit) and salinity in PPM (parts per million) or mg/L in the suggested fields.Īfter finding the results, you can correlate the density of water at room temperature for different salinity levels. If you are interested in calculating the density of seawater at different temperatures, there are online tools that are developed for the same purpose. Thus, water with lower salt content will float over water with higher salt concentration. In short, density of water is directly proportional to salinity. In general, the density of a matter is higher in solid form, as compared to the density of the same matter in liquid form.Īs with salinity, higher the level of salt concentration, the more will be the density of water, even at room temperature. However, as we are discussing the density of water measured in ground level for collected water samples, the pressure attribute is not considered in determining the density.

Of course, pressure does play a role in the subject of water denseness. While discussing this topic in detail, water density is found to vary with respect to the level of salinity (or other impurities) and fluctuation of temperature. However, it is to be noted that grams per milliliter (g/mL) and gram per cubic centimeter (g/cm 3) are not SI units. The logic is to divide the value of kg/m 3 by 1000 to get pure water density in g/ml. In other words, at the same temperature, the density of water in g/ml (or g/cm 3) is 0.99777. At room temperature (i.e., 22° C), the density of water in kg/m 3 is 997.77. With respect to the definition, the density formula is represented as Density (ρ) = Mass (m)/Volume (V).
