Thanks so much!

Good material. Thanks a lot!!

Thanks for your material

Good material, thanks. Do you have her book?

there is a PVT analysis of an oil reservoir that i want to use for EOS regression.
when i split puls fraction into three seudo components the calculated saturation pressure
will be 1622 psi while the observed saturation pressure is 1618 psia.
there are some questions:
how could i know that this is a good splitting?
can i use phase diagram of new mixture(with 3 pseudoComponents) as a valid reference for regression?
or I should compare phase diagram of new mixture with phase diagram of mixture before splitting?

what is more acurate?
phase diagram of mixture before splitting with 1450 psi calculated saturation pressure OR
phase diagram of mixture after splitting with 1622 psi calculated saturation pressure?

thank you

@Lost
I'm also doing my bachelor degree project in the same domain. Have you followed Gaussian Quadrature Method to split C7+? I'm actually stuck at calculating the dew point pressure (gas condensate fluid) using PREOS. I have a CVD data and any method that I have so far searched to calculate dew point pressure requires liquid mole fractions, which are zero at the first stage in my case.

I will really appreciate if you can help

please when i get to this site it ask me for user name and passwaord
please somone should help me out
i really need this material

saadi - Check out ( listen to the course) Whitson's lecture. I suspect that it will help you a lot. I am not a PVT expert and must say that after listening to all the files I learned quite a bit. However I do not need EOS in my everday work hence am not able to help you out.

Dear All,

Do we need hydrocarbon properties to create PVT

Thanks you

can anybody reupload the link? Link requires to type the password to access the webside.

The one I posted does not require any password to access the link (?????)

[hoanglongbk88]

I can not access this link, it requires me the user and password. I really these material because I am writting my dissertation with the title " phase behavior modeling for compositional simulation".
can you send me the link to my email: nguyenhoanglong2303@yahoo.com
thank you so much.
