Hysys Model - two wells tie-in together

[TennisBallz]

Hi all,

I am a newbie in Hysys. Please offer me some help!

Basically I am trying to tie-in a well's production into an existing flow line(pipeline) from another well. So that two wells will share one common line and go to a satellite location.

I am trying to use HYSYS to determine the following:
1) Hydrate formation temperature and methanol injection rate required
2) Whether the tie-in of a well will back off the production of the other well. Back pressure/
3) When a well is to be shut-in for 2 days, to allow for testing of another well, would there be hydrate issue for the shut-in well.

Please give me some idea on how to deal with this hysys model. Right now I have created 3 streams(oil,gas,water) for each of the well and mix them together to create one stream from each well. Whats the next step? Should I use pipe segment/pysys for the pipeline?

Thanks!

TennisBallz,

I think OLGA is a better tool then Hysys for this application

To elaborate on my advice:

2) you would need a well model with the production index, to determine the production reduction of the well based on increased back pressure. The well model can be included in Olga.

3) Olga is a better tool then Hysys to determine the cooldown effects on the Xmas/manifold piping. (some segments cool down faster then others depending on eg insulation and liquid holdup)
