Relative Permeability Model Comparison

Description

Compare relative permeability predictions from Corey, LET, and Honarpour correlations. Model selection affects waterflood performance predictions.

Models:

  • Corey: Simple power-law, 2 parameters per phase
  • LET: Flexible 3-parameter model per phase
  • Honarpour: Rock-type specific correlations

Corey Relative Permeability Curves

Generate oil-water relative permeability curves using the Corey power-law model. This simple model requires only endpoint values and exponents, making it ideal for screening studies.

LET Relative Permeability Curves

Generate oil-water relative permeability curves using the LET (Lomeland-Ebeltoft-Thomas) correlation. This model offers more flexibility than Corey for matching laboratory data.

Wettability Effect on Relative Permeability

Compare relative permeability curves for different wettability conditions using Ibrahim-Koederitz correlations. Wettability significantly impacts waterflood efficiency.

Stone Three-Phase Relative Permeability

Calculate three-phase oil relative permeability using Stone I and Stone II models. These models combine two-phase water-oil and gas-oil data to predict oil mobility when all three phases are present.

Honarpour Gas-Oil Relative Permeability

Generate gas-oil relative permeability curves using Honarpour et al. (1982) empirical correlations. Separate equations for sandstone (Eq A-4, A-5) and carbonate (Eq A-9, A-10) rock types.

Rock Compressibility Estimation

Estimate rock (formation) compressibility using Newman's correlations. Rock compressibility is critical for material balance calculations and pressure transient analysis.
