Drillsense LWD

Tool Architecture

Drillsense LWD provides real-time apparent neutron porosity, formation bulk density, and photoelectric factor data to characterize formation porosity and lithology while drilling. Tool sizes include 8 1/4 in, 6 3/4 in, and 4 3/4 in.

Azimuthal measurements provide density and porosity images for accurate formation evaluation. Potential pay zones can be detected and quantified early. Gas, oil, and other fluid contacts can be determined in real time while drilling. Acoustic caliper sensors supplement density caliper estimation with direct accurate hole size measurements
