pc_to_satn#
- pc_to_satn(pc, im)[source]#
Converts an image of capillary entry pressures to saturation values
- Parameters:
pc (ndarray) – A Numpy array with the value in each voxel indicating the capillary pressure at which it was invaded. In order to accomodateh the possibility of positive and negative capillary pressure values, uninvaded voxels should be indicated by
+inf
and residual phase by-inf
. Solid vs void phase is defined byim
which is mandatory.im (ndarray) – A Numpy array with
True
values indicating the void space
- Returns:
satn – A Numpy array with each voxel value indicating the global saturation at which it was invaded.
- Return type:
ndarray
Notes
If any
-inf
values are present the minimum saturation will start at a value greater than 0 since residual was present. If any+inf
values are present the maximum saturation will be less than 1.0 since not all wetting phase was displaced.Examples
