GeoTracker™

At-Bit Azimuthal Propagation Resistivity Tools

Screenshot_1-1.png

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.

TOOL FEATURE HIGHLIGHTS

  • Compatible with virtually any type of muds, which makes it a suitable choice to run in complex hole conditions

  • Very short length (2.92 ft. or 0.89 m) enables very close sensor-to-bit distance

  • High-capacity tool memory to record days of measurement data

  • Drop-in EM short-hop receiver module retains MWD tool string retrievability

  • Available in 4-3/4 in. and 6-3/4 in. collar sizes
