Reservoir Model

• Integrate existing data with new data from 3 wells
• Petrophysical studies to understand fundamental reservoir parameters
  • Crossections: electric logs, psuedoseismic
  • Log Analysis: PfEFFER
  • Core Analysis: standard description, thin sections, capillary pressure, and NMR

Volumetric Calculations

• Validate reservoir parameters
  • Ability of effective porosity, net pay thickness, and water saturation to support observed production volumes
