Relative Permeability Concept

[uae56]

Guys,
I have been trying to generate Kr curves for a reservoir where I do not have any data for. On the other hand I have defined some endpoints. The problem is that i tried to use several sheets provided by the forum and was only successful to generate curves for Water-Oil but Gas-Oil curves are not correct since I want Kro to be equal in both cases. I am sorry if I am confusing you but this is what I need :

The actual equations to manually calculate Kr for both water-oil and gas-oil so i can understand the process instead of using already generated sheets that i might be using wrong. I would appreciate your help if possible.

fine

just use any correlations in the laterature as corey
kr as function of saturation and saturation exponent which will give the curvature of kr relations


for a starting point assume your endpoints based on your wells performance if good producers kro = 0.8 krw = 0.1 something like
if the correlation donot give same end point for oil just put them equal and go ahead no issue my friend life is simple

after you'll get you core data you'll have higher confidence
