Hey all,

Here is a conceptual question:

Lets assume that there is a DFN model (particles that are attached to its neighboring particles via springs) and we inject fluid into one of the pore. Now the injected fluid will cause a change in the pore volume. This change in the pore volume will convert to a  change in pore pressure via the fluid bulk modulus. The change in pressure will cause the pore to expand. 

Now if the fluid bulk modulus was small (1e5 N/m^2) then the pressure would be small and the pore would not expand much. However, if the fluid bulk modulus was big (1e10 N/m^2) then the pressure would be big which will cause the pore to expand alot. However, because we inject fluid in the pore, we know the exact new volume of the pore. 

So how do we get the pore volume to match with the 'theoretical' pore volume without using the fluid bulk modulus as a calibration parameter?
