SPT GyroTracer

GyroTracer - Available for sale

Second-hand goods for sale - Excellent working condition.

The GyroTracer™ instrument is a highly accurate, extremely reliable downhole directional survey and orientation tool. Comprising of the latest technology, the SPT system uses gyro compassing 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™ is not affected by magnetic interference.

It can be run inside casing, tubing, drill pipe and magnetically disturbed ground. This 42mm diameter, easy to use system can be run in a variety of applications from shallow borehole to deep borehole surveying, single shot/multi shot, slim hole casing, orientation, whip stock kickoff and downhole motor orientation. Operating software to run the SPT instrument is extremely reliable and user friendly.

The GyroTracer™ 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 effcient as this is powered by battery supply and run on slick line.
