Gamma Ray Logging

Gamma ray logging is a technique used in oil and gas exploration to measure the natural gamma radiation emitted by rocks underground. As a tool moves through boreholes, it detects gamma rays produced naturally by certain minerals, especially shales. This information helps geologists differentiate between types of rock layers, identify hydrocarbon-bearing formations, and assess the geological characteristics of the subsurface. Essentially, gamma ray logging provides a detailed profile of underground rock formations, aiding in accurate resource evaluation and guiding drilling decisions.
