Make quick well-placement decisions with the most versatile at-bit geosteering technology.

Maximize the value of an asset by performing accurate wellbore placement in response to reservoir lithology variations or formation fluids changes.

Both standard version (150°C) and high-temperature version (175°C) are available.

PLACE YOUR WELL ACCURATELY WITH THE INDUSTRY’S FIRST AT-BIT TOOL THAT OFFERS BOTH AZIMUTHAL RESISTIVITY AND AZIMUTHAL GAMMA IMAGES.

FEATURES & BENEFITS

  • Provides both compensated azimuthal propagation resistivity and azimuthal gamma measurements near the bit from one sub

  • Capable of measuring 16 sectors of gamma and resistivity in memory and up to 4 quadrants of each in real time

  • Measures both bulk resistivity and total gamma near the bit

  • Designed to run below motor or above RSS

  • Compatible with virtually any type of muds including oil-base mud

​

APPLICATIONS

  • Stop precisely at desired casing or coring points

  • Illuminate thin beds with high-resolution resistivity images

  • Detect formation resistivity heterogeneity or fluid contacts via azimuthal resistivity images near the bit

  • Navigate reservoirs with 3D bedding variations

  • Improve well placement reaction time with less risk of drill-out

GeoTracker DUO provides near bit azimuthal resistivity and azimuthal gamma, whether in rotating or sliding mode, to give early warning of approaching bed boundaries before the target zone is exited.

​

GeoTracker DUO provides bulk resistivity and total gamma measurements near the bit which may give early indication of an overpressured zone or lithology change.

​

GeoTracker DUO, when run below a mud motor, transmits data across the motor, via a field-proven EM short-hop communication system, to the MWD system above the motor for further transmission to the surface in real time.

​

GeoTracker DUO performs in any type of wells drilled with water-base mud, oil-base mud, or other types of drilling fluids.
