kr3p_StoneI_SwSg: Generate a matrix of three-phase relative permeability data...

In Rrelperm: Generate Two- And Three-Phase Relative Permeability Estimates

Description

The 'kr3p_StoneI_SwSg()' creates a table of three-phase oil relative permeability data for water, gas, and oil saturation values between zero and one. This model reads the water, and gas saturation values in the three-phase region as water, and gas saturation inputs into two-phase relative permeability models

Usage

kr3p_StoneI_SwSg(
  SWCON,
  SWCRIT,
  SOIRW,
  SORW,
  SOIRG,
  SORG,
  SGCON,
  SGCRIT,
  KRWIRO,
  KROCW,
  KRGCL,
  NW,
  NOW,
  NG,
  NOG,
  NP
)

Arguments

SWCON	connate water saturation, fraction
SWCRIT	critical water saturation, fraction
SOIRW	irreducible oil saturation, fraction
SORW	residual oil saturation, fraction
SOIRG	irreducible oil saturation, fraction
SORG	residual oil saturation, fraction
SGCON	connate gas saturation, fraction
SGCRIT	critical gas saturation, fraction
KRWIRO	water relative permeability at irreducible oil
KROCW	oil relative permeability at connate water
KRGCL	gas relative permeability at connate liquid
NW	exponent term for calculating krw
NOW	exponent term for calculating krow
NG	exponent term for calculating krg
NOG	exponent term for calculating krog
NP	number of saturation points in the two-phase relative permeability tables, the maximum acceptable value is 501. The number of data points in the three-phase relative permeability table is (0.5 * NP * (NP + 1))

Value

A matrix with water saturation, gas saturation, oil saturation, and oil relative permeability values, respectively.
