258 Principles of Applied Reservoir Simulation

Capillary pressures are defined as PCOW = Po - Pw and
PCGO = Pg - Po where Po, Pw, and Pg are the oil-, water-,
and gas-phase pressures, respectively.

4. ITHREE, SWR
ITHREE Code specifying desired relative permeability option.
SWR Irreducible water saturation (fraction).

Code Value Meaning
0 Oil relative permeability read from the relative perme-
ability data for the two-phase water/oil system.
TTUTQpTn
1 i JnLKJiD
1 Oil relative permeability calculated from Stone's three-
phase relative permeability model

Repeat records 1 to 4 a total of NROCK times.
