I am simulating a well with GOR at standard condition as 2000 standard cubic feet / barrel (SCF per barrel)

 

The well stream go through separation in high , medium and low pressure separator follow by a tower for stabilizing

 

the pressures are 500 psig, 300 psig, 90 psig and 55 psig

 

i have 2000 barrels per day flowrate for the well fluid. however when i simulate total gas i get is 2.76 mmscfd

 

i do not get 2000 scf / barrel x 2000 barrel per day = 4000000 SCF or 4 MMSCF/d

 

what could be reaason for this reduction in gas amount

it means that selected model for VLE doesn't replicate measured values, there are many possible reasons, a common practice is to redefine the list of components and fractions in order to provide the best fit to measured data, there are several posts discussing this topic in this forum.
