Capillary Pressure Models Comparison
Compare capillary pressure curves using Brooks-Corey and Van Genuchten models. Includes Leverett J-function for scaling between different rock types.
Capillary Transition Zone Profile
Compute water saturation as a function of height above the free water level using Brooks-Corey capillary pressure. Essential for initializing reservoir simulation models and estimating OOIP in the transition zone.
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.
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.
J-Function Capillary Pressure Scaling
Scale capillary pressure from a reference core plug to a different rock type using the Leverett J-function. Essential for transferring SCAL data between reservoir facies with different porosity and permeability.
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.
Relative Permeability Model Comparison
Compare relative permeability predictions from Corey, LET, and Honarpour correlations. Model selection affects waterflood performance predictions.
Rock Compressibility Estimation
Estimate rock (formation) compressibility using Newman's correlations. Rock compressibility is critical for material balance calculations and pressure transient analysis.
SCAL Endpoint Analysis
Tabulate SCAL endpoint data from multiple core plugs (Swi, Sorw, Krow@Swi, Krw@Sorw), apply user-defined Corey exponents, and generate model relative permeability curves. This is the "lab data to simulation input" workflow — taking raw core measurements and producing smooth kr curves for reservoir simulation.
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.
Waterflood Fractional Flow Analysis
Buckley-Leverett fractional flow analysis for waterflood performance prediction. Computes water fractional flow curve from Corey relative permeability and fluid viscosities, applies the Welge tangent construction to determine breakthrough saturation and oil recovery factor.
Wettability Effect on Relative Permeability
Compare relative permeability curves for different wettability conditions using Ibrahim-Koederitz correlations. Wettability significantly impacts waterflood efficiency.
