What it means

Petrophysics is the study of the physical and chemical properties of rocks and how fluids (oil, gas, water) move through them.

What it involves

• Interpreting well logs (gamma ray, resistivity, neutron, density).
• Estimating porosity, permeability, water saturation, and lithology.
• Correlating data from core samples and well logs.

Tools used

• Schlumberger Techlog, IP (Interactive Petrophysics), GeoFrame, RokDoc.

Why it’s important

Accurate petrophysical analysis ensures correct estimation of reserves and helps in choosing the right production techniques.
