Good day everyone, 

 

I've been trying to simulate a GOSP, and I have managed to get it converged but i have some doubts on my methodology. 

 

First of all, I have two Wells' data, where i utilized the oil & gas Feed tool to input the oil properties (GOR, water cut, oil density, light ends mol% and stock tank oil flow-rate). However, the thing that i still skeptical about is the number of stages. 

 

In my simulation i have used only two stages, the first one is at the reservoir conditions and the second is at stock tank conditions. 

 

while i have three three separators before the stock tank (HP @ 250 psig, MP @ 50 psig and LP @ 2 psig)

 

with following this methodology the simulation solved but the stock tank vapor vent pressure is 0 psia which makes no sense to me! 

 

I tried to utilize the adjust block (which is my first time to use) but with no luck at all, 

 

 

so i do appreciate your informative guidance on this subject. 

 

see attached wells' data.

You need to model the whole process, including the separators.
