For using compositional model (in Hysys), the following analysis of produced oil and gas at standard conditions are exist:
In hand calculation, a single segment with Pav= P1 was used (for first iteration).
I didn’t find any reliable correlation for calculation of dissolved gas specific gravity, and therefore the specific gravity of free gas was selected from HYSYS software at input conditions: γgf= 0.6397
Calculation of Rs and γgdneeds a try and error, based on these equations:
Volume flow rate of free gas at inlet conditions can be calculated with using Bg:
Viscosity of oil and gas and surface tension between them can be calculated as:
Therefore, the two-phase no slip properties can be calculated as follows:
Liquid Hold and ρs:
Pressure gradient due to friction:
