The latest instrument added to Gasway 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.
This north seeking gyro instrument can accurately survey all well profiles from vertical to horizontal. 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.

The Universal Calibration Stand for GyroTracer Directional is a simple to use, yet advanced design. This small, non-magnetic stand is light weight, durable and useful for testing many downhole survey instruments.
The purpose of the Universal Calibration Stand is to calibrate gasway instruments. Its second and just as important use is for highly accurate testing. Simply set the stand facing to geographic north. Once the frame has been levelled, place the tool in the stand and begin testing or calibrating.
The Universal Calibration Stand enables the customer to calibrate their own tools if required, on site, in a few hours. This saves on numerous days of down time and expensive freight costs. It also gives the customer the option of extremely accurate quality control checks of instruments in the stand and the option to simulate real situations as it has all the necessary positions.
Calibration of the gasway instruments is a very simple procedure. Tools can be tested in all inclinations (0-360º), toolface (0-360º) and azimuth angles (0-360º).
