An API calibrated tool which provides radial gamma ray, ultrasonic imaging and caliper, azimuthal unipole sonic and precision inclination measurements for geosteering & well logging.

Scientific Drilling’s new Unconventional Logging Tool (ULT) is a compact, integrated LWD system that encompasses three principal services optimized for logging unconventional reservoirs.  In addition to its benefits for geosteering, the ULT offers a cost-effective solution for intelligent completion designs to improve production and optimize costs.

With all three of the ULT sensors providing azimuthal data while rotating, a 3-dimensional model of the reservoir can be built with the Logging While Drilling data.  The integrated sensor design not only shortens the tool length to 15’, but also reduces the LIH cost compared to other service companies providing similar measurements with independent collar designs.

The ULT’s innovative design is an industry-first, which proves Scientific Drilling’s continued commitment to the development of new technologies to further optimize the drilling, evaluation, and development of resources.
