FracView™ LWD Acoustic Borehole Imager and Caliper

The FracView™ LWD Borehole Imager provides high-resolution borehole images and caliper data while drilling with oil-based or water-based muds.

The images are acquired by two dynamically focused ultrasonic transducers capable of automatic adjustment of focus to the varying distance to borehole wall while drilling. The tool also records wide-band vibration, acceleration, shock, orientation, and instantaneous collar motion trajectory via an integrated Drilling Dynamics monitor package, allowing for identification and flagging of drilling issues such as stick-slip and whirl.

As a memory tool with its own battery power and standard API mechanical connections, FracView is “service-company-agnostic” and can be included
in any BHA.
