Project Workflow

Generalized Project Workflow

1. Preprocessing work (LAS files)
   • depth shift curves
   • interpret null values
   • correct curve units for consistency
   • create synthetic curve data to remedy intervals of bad data
2. Review routine core data and integrate into the quantitative analysis
   • check core data against log data and depth correct
3. Review special core data and integrate into the quantitative analysis
   • electrical properties data (a, m and n)
   • capillary pressure data
   • XRD mineralogy data
4. Run quantitative log analysis, using our proprietary calculation sequence, based on parameters picked on a per well and per zone basis
   • shale volume
   • total organic carbon (for organic rich reservoirs)
   • effective porosity (corrected for clay bound water and organic matter)
   • lithology
   • water saturation
   • permeability index
   • net pay flag and associated summaries
5. Reconstruct sonic and density logs, based on calculated bulk mineral volumes and fluid volumes
   • corrects for light hydrocarbon, bad hole and organic matter effects
6. Use reconstructed logs to calculate accurate water filled mechanical rock properties
   • bulk modulus
   • shear modulus
   • vertical Biot’s factor
   • dynamic Young’s modulus
   • static Young’s modulus
   • Poisson’s ratio
7. Map and review results with Geoscience team
   • petophysical data are plotted on a map and contoured
   • identify outliers and review
