Discover your 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 resistivity log measurement aids in estimating water or oil saturation, and evaluating the producibility of the formation.

Compass 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 geosteer through complex geologic structures, while maximizing exposure of the well to the most productive zones.

Our latest LWD innovation provides you with unmatched visualization of the true structure of your reservoir.

Let us help you enhance reservoir understanding and place wells accurately, maximizing your asset value.
