Geosteering Services
Dynamic, interactive and intuitive geosteering is the key to accurate wellbore positioning - and Halliburton has the innovative technologies, applications and people to help point you in the right direction at your wellsites.


ABG™ At-Bit Gamma Sensor
Real-time geosteering with the Geo-Pilot® rotary steerable system

ADR™ Azimuthal Deep Resistivity Sensor
LWD sensor provides deep reading (up to 18 feet into the formation), directional and high-resolution images that give early warning of approaching bed boundaries before the target zone is exited . Also provides a traditional multi-frequency compensated resistivity sensor. This one tool provides over 2,000 unique measurements for both precise wellbore placement and more accurate petrophysical analysis.

AFR™ Azimuthal Focused Resistivity Sensor
LWD sensor produces high resolution resistivity images for identifying dip, fractures and borehole breakout. Also provides an omni-directional, laterolog-type resistivity data, electrical images of the formation, and at-bit resistivity (ABR) measurement.

ALD™ Azimuthal Lithodensity Sensor
The ALD LWD tool features high-quality measurements of formation density and photoelectric (Pe) factor for reliable reservoir evaluation. These measurements are combined with azimuthal binning of data and an acoustic stand-off sensor to provide images of the formations surrounding the borehole, from which formation dips can be estimated, and measurements of borehole size and shape. The density and Pe measurements from different tool orientations are segregated, so that accurate measurements can be obtained, even if the borehole is enlarged

GABI™ Downhole Drilling Motor
Sperry Drilling’s GABI™ motor is equipped with a GABI™ sensor providing at-bit azimuthal gamma ray and inclination measurements for improved geosteering and optimum wellbore placement.

LaserStrat® Wellsite Chemostratigraphy Service
Surface analysis of drill cuttings providing elemental data for chemostratigraphic correlation, improved geosteering, and enhanced formation evaluation.

StrataSteer® 3D Geosteering Service
StrataSteer 3D is the heart of our wellbore positioning service, crucial to placing a well, especially in smaller targets that often require complex well paths and more accurate wellbore positioning.
