Relative Permeability Using Corey Model

[bayan]

please help me if there is any VBA macro to generate relative permeability curve based on Corey correlation for oil- water-gas system to be used in reservoir simulation throug change parameters, i.e. end point, etc. to match your simulation or field data.

thank you in advance

Hey,

You can use Petrel Re or Mbal to generate relative permeability table

There are quite a few around, but they are all very simple. It would be a good exercise for you to build your own in Excel

Step 1: create a table of normalized saturation values (Swn) from 0 to 1 in however many increments you want

Step 2: calculate for each Swn value, Kro and Krw as Kro = Kro_max*(1-Swn)^no, Krw = Krw_max * Swn^nw

Step 3: Calculate Sw at each Swn, Sw = Swn*(1-Swc-Sorw)+Swc

Step 4: Add a single line for Sw = 1, with Kro = 0 and Krw=1

Similar process for water gas systems.

Oh, and please just post questions in forum in future - it just fills my in-box to get private messages in addition to forum posts. Thx
