Borehole logging techniques

Borehole logging involves sending specialized tools into drilled wells to gather information about underground rock and fluid properties. As the tools descend, they measure parameters like rock type, porosity, temperature, and fluid content, providing detailed data about subsurface conditions. These measurements help geologists and engineers assess zones for oil, gas, water, or minerals, and guide drilling decisions. Techniques include electrical resistivity logging, sonic logs, and gamma-ray logs, each providing different insights based on the method used. Overall, borehole logging is a crucial process for understanding underground geology in a non-invasive, efficient manner.
