Resistivity Logging

Discover a well’s most productive zones with resistivity logging services

Recording what’s below the subsurface can help you identify where hydrocarbons are located in your reservoir. Resistivity logging-while-drilling (LWD) tools gather data to determine which formations are filled with water (good conductors of electricity) and those filled with hydrocarbons (poor conductors of electricity). The combination of resistivity logs and porosity measurements aids in estimating water or oil saturation, and evaluating the producibilty of the formation.

Sperry Drilling LWD resistivity tools offer different types of resistivity sensors to accurately detect variations in resistivity around the borehole, from a few inches (centimeters) to hundreds of feet (meters) away. This allows you to safely and confidently navigate and geosteer through complex geologic structures, while maximizing exposure of the well to the most productive zones.
