COREPRO is a versatile processing utility for both small and large volumes of routine core data. Core data can be combined into multi-well files or subdivided into discrete reservoir layers in preparation for grouping and averaging to describe the vertical and areal distribution of physical properties of the reservoir. COREPRO's capabilities include:

• Arithmetic, geometric and harmonic averaging by layer
• Vertical to horizontal permeability ratios
• Dykstra-Parsons coefficient
• Data filtering or moving averages
• Permeability controlled porosity cut-offs
• Application of transforms for:
• Net overburden stress
• Gas slippage (Klinkenberg)
• Dry to brine saturated permeability
• Specific to effective permeability
• PDPK mini-permeameter and PSP-300 porosity processing
• Heterogeneity indices (Hi) and reservoir quality indices (RQI) for flow unit identification
• Cross-plotting, probability plots, histograms, automated and user defined plots

• Cumulative porosity and permeability capacity plots
• User-defined X, Y, and Z axes
• Permeability blocking computations for recovery factor prediction
• Interactive incorporation of production data to allow history matching and calculation of effective drainage area
