GeoTracker™
At-Bit Azimuthal Propagation Resistivity Tools

An enabling technology for geologists, petrophysicist and drilling teams to make quick decisions while drilling.
Together with a deep azimuthal resistivity boundary mapping tool, GeoTracker eliminates the geosteering blind spot up to the bit.
Both standard version (150°C) and high-temperature version (175°C) are available.

MAKE YOUR WELL PLACEMENT DECISIONS WITH THE INDUSTRY’S FIRST AT-BIT PROPAGATION RESISTIVITY TOOL
FEATURES & BENEFITS
-
Opens new horizons by providing compensated propagation resistivity and imaging right behind the bit
-
Maps approaching bed boundaries or water zones up to 30 in. (0.76 m) apart
-
Capable of measuring 16 sectors of attenuation and phase-shift resistivity in memory and up to 4 quadrants of each in real time
-
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 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 provides near-bit azimuthal resistivity measurements for earlier warning of approaching bed or fluid boundaries.
​
GeoTracker provides bulk resistivity measurements near the bit which may give early indication of an overpressured zone.
​
GeoTracker, 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 performs in virtually any type of wells drilled with water-base mud, oil-base mud, or other types of drilling fluids.
