GyroTracer Directional™ 42mm [North Seeker]

Description Features and benefits Specifications Dimensions Downloads

The GyroTracer Directional™ instrument is a highly accurate, extremely reliable downhole directional survey and orientation tool. Comprising of the latest technology, the SPT system uses gyro compas- sing method to find direction. As it is a North Seeking Gyro, all measurements are in reference to geographic north. Unlike other downhole survey or magnetic tools, the GyroTracer Directional™ is not affected by magnetic interference. It can be run inside casing, tubing, drill pipe and magnetically disturbed ground.

This easy to use system can be run in a variety of applications from shallow borehole to deep borehole surveying in continuous mode, single shot/multi shot, slim hole casing, orientation, whip stock kick-off and downhole motor orientation. Operating software to run all SPT instruments is very reliable and user friendly.

The GyroTracer Directional™ package comes with both wireline and memory mode option. Wireline mode is run from an electric line cable transmitting real time data to the computer at the surface. Mono or multiple conductor cable can be used. Memory
mode is fast and cost efficient as this is powered by battery supply and run on slickline.
