Characterize formation porosity and lithology while drilling

The adnVISION azimuthal density neutron service provides real-time apparent neutron porosity, formation bulk density, and photoelectric factor data to characterize formation porosity and lithology while drilling. These nuclear measurements are borehole compensated for improved accuracy. Tool sizes include 8 1/4-in (stabilized or slick), 6 3/4-in, and 4 3/4-in.

Azimuthal measurements of rock and fluid properties in all quadrants provide more accurate formation evaluation, better identification of reserves, and new diagnostic capabilities. Potential pay zones can be detected and quantified early. Gas/oil and other fluid contacts can be determined in real time while drilling. Downhole gas influxes can also be detected earlier with an ultrasonic caliper.

The adnVISION service's radioactive sources are safely contained within the drill collar and are connected to each other by a titanium cable so they can be easily fished by wireline through drillpipe. This wireline retrievability reduces environmental concerns and improves safety.
