Resistivity Logging

Resistivity logging is a method used in oil and gas exploration to measure how well rocks in a borehole conduct electricity. When electrical current is passed through the rocks, their resistance reveals the types of materials present. For example, oil-filled rocks typically have high resistivity, while water-filled rocks have low resistivity. This information helps geologists identify potential hydrocarbon zones and determine the type and amount of resources in the underground formations. In essence, resistivity logging provides a detailed electrical profile of the subsurface, aiding in more accurate assessments of underground reservoirs.
