Regarding pc_curve

[jayaraj777]

I am trying to solve the invasion of air in a network initially filled with water. I used the IvasionPercolation algorithm for this. I was able to run the code but when I try to plot the capillary pressure vs air saturation, I am not getting a proper plot. For the same value of capillary pressure, I am getting many air saturation values. Please suggest me a solution for this.

Thanks
Jayaraj

This curves is perfect! Invasion percolation is the process of invading every single pore in sequence, so usually the pore/throat being invaded is large (low pressure), but then occasionally the fluid will breach a small pore/throat (high pressure) and the capillary pressure will spike. The envelope of peak or spike pressures on the right-hand edge of the above data is the drainage capillary curve that you're looking for. You can get the drainage curve using the 'Drainage' algorithm.

Thanks for the reply sir. How can I get capillary pressure vs average air saturation of the network curve. Please suggest me a solution. Thanks Jayaraj

The number of tech support questions we receive lately is just too much for us to handle. Our software is a tool, not a service, so we really have to limit how much time we spend on helping. I'm sorry about that. Here is a link that explains the IP vs OP stuff that might be useful for you.
