Description Features and benefits Specifications Dimensions Downloads

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

Built inside a Thermal Flask with continuous surveying capability 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™ HT does not require any surface alignment or surface calibration prior to survey.
