Schlumberger

UBI Ultrasonic Borehole Imager

Our multidisciplinary interpretation experts work with you to determine structural information through image and dip analysis of measurements made with the UBI ultrasonic borehole imager. Single-well cross sections can be generated to help identify complex folding and faulting. Fractures, faults, slumps, and other features can be identified and characterized. Textural information such as the porosity distribution in carbonates and the sorting index in sandstones can be obtained, along with net sand calculation in highly laminated reservoirs.
