Wettability Effect on Relative Permeability

Description

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

Wettability Characteristics:

  • Water-wet: Oil floats on water film, favorable for waterflood
  • Intermediate: Mixed wettability, complex behavior
  • Oil-wet: Water beads up, less efficient waterflood

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.

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.

Rock Compressibility Estimation

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

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.
