Advanced borehole imaging independent of mud type
Improve structural interpretations
The UBI ultrasonic borehole imager lets you analyze fractures and the stress regime and conduct borehole stability studies. Your structural interpretations are not influenced by mud type. Borehole stability and breakout information can be derived from an accurate borehole cross section delivered by the high-resolution openhole measurements of the UBI transducer.
Measure amplitude and transit time accurately
This processing technique results in improved accuracy, avoids cycle skips and reduces echo losses. The tool’s higher frequency yields higher image resolution. The lower frequency gives a robust measurement in highly dispersive muds.
Discern bedding and structural dip
Complement UBI information with images from an array of high-resolution measurements of formation resistivity otained with the FMI fullbore formation microimager, OBMI oil-base microimager, or ARI azimuthal resistivity imager.
Reduce rig time
Many drilling problems, especially those in deep wells, are caused by shear sliding along fractures. In one case, UBI logging solved repetitive problems by guiding reduction of the mud weight from 1.6 to 1.25 g/cm3.
