6 PERMZ
PERMZ Permeability in z direction (md).
If KKZ = -1, read one constant value.
If KKZ = 0, read KK values (one for each layer).
If KKZ = +1, read II x JJ x KK values (one for each block).

24.3.2 Modifications to Porosities and Permeabilities

1. Heading Up to 80 characters.

2 NUMP, NUMKX, NUMKY, NUMKZ, IPCODE
NUMP Number of regions where porosity (PHI) is changed.
NUMKX Number of regions where x direction permeability
(PERMX) is changed.
NUMKY Number of regions where y direction permeability
(PERMY) is changed.
NUMKZ Number of regions where z direction permeability
(PERMZ) is changed.
IPCODE = 0 means do not print the modified distributions;
= 1 means print the modified distributions.

3 II, 12, Jl, J2, Kl, K2, VALPHI
Omit this record if NUMP = 0.
11 Coordinate of first region block in I direction.
12 Coordinate of last region block in I direction.
J1 Coordinate of first region block in J direction.
J2 Coordinate of last region block in J direction.
Kl Coordinate of first region block in K direction.
K2 Coordinate of last region block in K direction.

Code Value Meaning
<0 New value of porosity for region (fr).
•\J1 TA/fD
iNUMr
>0 Multiply value of porosity by VALPHI.
