The images and borehole size/shape measurements are acquired via dual dynamically-focused ultrasonic transducers capable of highly flexible, electronically controlled changes to focal depth and other transducer transmit and receive characteristics. The tool also records wide-band vibration, acceleration, shock, and orientation via an integrated Drilling Dynamics monitor package, allowing for identification and flagging of drilling issues such as stick-slip and whirl. Currently deployed as a memory tool with its own battery power and standard API mechanical connections, the FracView® tool is “service-company-agnostic” and can be included in any BHA.

The FracView® 675 High-Resolution LWD Imager with 6 3/4 in. nominal collar size provides high-resolution borehole images, caliper, and dynamics data while drilling with oil-based or water-based muds.
