Feasibility study

• Well log studies (AI, Vp/Vs, GI, Porosity, NTG, VShale, Sw studies)
• Well-seismic tie
• Gather and full-stack synthetic (Zoeppritz and Elastic wave modeling)
• Comparison with the true data at the zone of interest
• Data quality assessment
• Quality enhancement by gather conditioning

Band-limited inversion

• Fluid volume and lithology volume
• Seismic net pay map

Post-stack inversion

• Sand/ carbonate probability volume
• Predicted porosity volume

Pre-stack inversion

• AVO analysis in intercept and gradient domain
• Inversion for reservoir parameters P-impedance, S-impedance, and Density.
• Fluid volume and lithology volume
• Litho-fraction (for example, VShale) volume
• Probabilistic litho-facies classification

Multi-attribute regression and Neural-network prediction

• Water saturation prediction volume
• Porosity prediction volume
• Lithology prediction volume
