Description

NOV’s Tolteq™ iSeries NXT Azimuthal Gamma-ray probe enables more accurate geosteering with its ability to measure gamma measurements around the wellbore and provide deeper understanding of the position of the wellbore within the target zone while drilling.

The iAZG-NXT module accurately measures the natural gamma-ray of the formation in 16 sectors around the wellbore while rotating the drillstring. Using the fast-pulsing capability of the Tolteq NXT pulsers, up to four sectors can be transmitted to surface in real-time at the same frequency as conventional bulk gamma-ray measurements are provided by standard MWD systems today.

Proven for 10 years on the BlackStar MWD platform, the azimuthal gamma-ray technology has been developed and adapted for the Tolteq MWD platform. The iAZG-NXT module is an integrated addon to the existing Tolteq MWD platform, replacing or supplementing the conventional iRGM Gamma-ray module.
