Geo Tracker

Place your well accurately in the most productive zone by At-Bit Azimuthal Wave Propagation Resistivity LWD Tool. Great LWD solution for geologists, petro-physicists, and drilling teams to make quick decisions while drilling.

At Bit

GeoTracker is one of the best resistivity tools in the industry, as it opened new horizons in the oil industry by providing compensated propagation resistivity and imaging near the bit. GeoTracker allows you to make geo-steering decisions confidently with real-time resistivity imagery near the bit for precise wellbore placement. It is a best choice for customers running in high temperature wells due to its ability to operate upto 175° C.

GeoTrackerprovides near-bit azimuthal resistivity and directional measurements to give early warning of approaching bed boundaries before the target zone is exited, allowing the well to be placed in the most productive part of the reservoir.

GeoTrackerprovides high-resolution, detailed images of structural and stratigraphic features allowing for accurate determination of dip and fracture orientation. Understanding dip from real-time images near the bit helps improve wellbore placement in the reservoir.
