Well logging is a fundamental part of the formation evaluation process, providing valuable information about the subsurface and helping engineers understand what is happening inside the wellbore.
🔹 Gamma Ray (GR) – Identifies shale and helps determine formation boundaries.
🔹 Resistivity Logs – Help evaluate fluid saturation and identify potential hydrocarbon-bearing zones.
🔹 Density & Neutron Logs – Provide insights into porosity and lithology.
🔹 Caliper Log – Evaluates borehole condition and identifies washouts or irregularities.
🔹 Sonic Log – Provides information about acoustic properties and can support porosity and geomechanical evaluations.
By integrating different logging measurements, engineers can build a clearer picture of lithology, porosity, fluid saturation, and reservoir quality, supporting better decisions throughout the well lifecycle.
🎥 In this video, let’s take a look at the well logging process and how downhole measurements are transformed into meaningful formation data.
