[ Help ] How to Determine Pressure Drop in PipeSim

[dzaky_petrol@yahoo.com]

Assalamualaikum.Wr.Wb

Hai every body,.
for i first time, may i introduce my self, i'm dzaky . i'm a collage student in one of university in Indonesia. Now, i still doing my final assignment about "analysis Pressure drop in one filed with multiphase correlation".

for first time, i'm sorry if i ask about my problem on in-correct thread here...

actually i plan to determine the pressure drop of several well in one oil field, the pressure drop which i want to determine about 2 point , it's from well head to storage station, actually the field is multiphase flow,
I plan to determine it with PipeSim with horizontal multiphase correlation such as Dukler I/II correlation, beggs and Brill Correlation, or Hagedorn and Brown Correlation. I plan to determine it in PipeSim.
Can i determine it in pipeSim?? actually i still confuse to operate the software, have any one ever determine the pressure drop between 2 point with PipeSim?? ( i hope someone can share his/her experience in this problem...)

i still confuse , what should i do in operate the software, what should i do first? should i build the model with well/pipeline model option or i should make it with network model...?? and what option should i take in operations toolbar : the pressure/temperature profile? or other option??

hope some one here can help me about my problem....

and thanks a lot for time and attention every one here who willing help me here... hope Allah will bless your kindness .

Dear dzaky_petro
You must run the network.
1- Define a well (add source from the left bar)
2- Double click on it and set temperature and flow rate (gas or liq, if they are gas wells or oil wells respectively)
3- Define all wells as above
4- Add a junction from the left bar menu
5- Connect all wells to the junction with branch tool (from the left bar menu)
6- Now you see some pipeline between wells and junction named B1, B2,..
7- Double click on each B and define your pipeline (ID, Thickness, Profile, Temperature, Heat transfer U, above or underground,…)
8- Now you should have a receiver maybe refinery, end user,... (add a sink from the left bar menu)
9- Connect the junction and sink by a branch
10- If you need pressure drops in the manifold (junction), double click on pipeline between junction and sink, remove pipeline and then connect them with connector tool (on the top bar menu)
11- If you want to transmit the fluid as a single phase, add a separator between junction and sink. Gas type separator removes gas from the line and send oil to the pipeline or sink.
12- Double click on the sink and set the pressure or rate. It’s better to set the pressure (the trail will have the better answer)
13- Run the model
14- You can see the pressures by report tools or move mouse over any points (Source, Pipeline, Junction and Sink)
Good luck friend

Thanks a lot Mr.motaleby to your suggestion in my problem..
i will try to build it first Mr.

Thanks a lot...

Mr.Motaleby..
may i ask you something....

i have tried the illustration that you given to me,..
for exercise i tried model contain 2 source....and i follow all of the your instruction , but while i run it the are something error here...

the error reported that...
"Invalid Model
Error in Boundary condition : number of pressure, Flowrate or PQ Curve spec doesn't match number of source/sink"...

actually.
i run 2 source with different Pressure and flowrate...
source_1 : P = 75 psi, Q=378 stb/d
source_2 : P= 105 psi, Q=868 stb/d..



here is my model....

Dear Dzaky
as i guessed you've entered too many known parameters for your sources and sink. you must set one of the "P and Q" for a source or sink. I suggest set Q for the wells and P for the sink. Double click on the wells and delete P value and then remove Q value from the Sink. If you do these right, you'll see below the wells Q (current: PQ) and below the Sink P (current: PQ).
Keep on Engineer!

oh...

my mistake , i think i can input both P and Q in one source, but it can't...

so, it's alternate while we enter P in Source 1 in other way, we have to enter Q in sink...

Ok. i'm understand Sir....

Thanks a lot Mr.Motaleby, i hope Allah SWT will bless you for your goodness to me Mr.Moteleby....
Thanks again Sir...
