Outline
• Brief introduction and objectives of petrophysical
study
• Main objective:
– to evaluate all available formation data to provide
petrophysical parameters ( Ø, Sw and NTG) needed for
the resource assessment process and reservoir
modeling for XXX field
2.1 Introduction & Objectives
• Brief explanation on the available data provided
for petrophysical study of each well
• May summarize in table
• E.g. wire log, PVT, etc.

Reservoir Rock and Fluid Properties
• Lithological determination
• Permeable and non-permeable zones
• Shale volume
• Porosity
• Water saturation & Rw
2.3 Petrophysical Evaluation
Fluid Contacts
• Water and HC bearing zones
• Fluid types
• MDT pressure plot (verify fluid contacts with log)
2.3 Petrophysical Evaluation
Cut-off Parameters
• Cut-off definition
• Sensitivity analysis to derive Vshale and porosity
cut-off
• NTG determination
2.3 Petrophysical Evaluation
• Summary of petrophysical parameters and
properties derived from the available data
2.4 Results Summary
• Any uncertainties faced during data interpretation,
the impact and measures/assumptions adopted
• E.g. lack of data
2.5 Uncertainties
THANK YOU & ALL THE BEST…!!!
