Gamma Ray Log Interpretation in Petrel | Identify Sand & Shale Like a Pro
Gamma Ray Log Interpretation in Petrel | Rock Type Identification Explained
In this video, I walk you through how to interpret Gamma Ray logs in Petrel and use them to identify rock types such as sand and shale — a fundamental skill in petrophysics, reservoir characterization, and formation evaluation.
This is a practical, step-by-step Petrel workflow, not just theory.
🔍 What you’ll learn in this video:
✔ What Gamma Ray logs represent
✔ How to differentiate sand vs shale using GR logs
✔ How to visualize and interpret Gamma Ray logs in Petrel
✔ How GR interpretation supports reservoir characterization
