OLGA SIMULATION, HELP!

OLGA SIMULATION, HELP!

OLGA SIMULATION, HELP!

(OP)
Hi, I am starting to use OLGA and I have to learn it by myself... so I need a help!!
I have to simulate the following things:

1. Fill a pipeline that has a very irregular profile (250 km long, 28 inches) with air (can I do it directly with using "Initial Conditions"?).

2. Fill the pipeline with water (I think that air will remain in peaks). How can I estimate the mass flow of the water?

3. Determine the pressure that have to be given to the pig to clean the pipeline.

Do I need the compositional tracking module?

Can you give me any suggestions?

Thank you!!!

 

RE: OLGA SIMULATION, HELP!

1. yes, you should do it using initial conditions,

2. More information needed. Do you want to fill it with water at a specified mass flowrate or do you have pressure boundaries or what? Please clarify

3. You dont give pressure to a pig? do you mean what pressure differential do you need to drive the pig to clean the pipe?

No you should not need comp tack to do any of these, but you need to give a lot more information and be a bit clearer in your questions before I can help! :)
