GyroTracer Directional

GyroTracer Directional™

The latest instrument added to SPT’s range of tools is the GyroTracer Directional™, a high-speed continuous North Seeking Gyro. The GyroTracer Directional™ surveys the wellbore in continuous mode at speeds of up to 150 m/min while simultaneously sending data to the surface equipment in both wireline and memory mode.

This north seeking gyro instrument can accurately survey all well profiles from vertical to horizontal, Pumpdown capability and continuous surveying at high latitudes or inclinations with no accuracy degradation.

Producing one of the most all-round and versatile north seeking gyro instruments on the market. Unlike other continuous gyro systems, the GyroTracer Directional™ does not require any surface alignment or surface calibration prior to survey.
