OUR TOOLS
SURVEYING - North Seeker

The latest instrument added to Gyro Wireline Services Limited 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

Universal Calibration Stand

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 Gyro Wireline Services Limited 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 Gyro Wireline Services Limited instruments is a very simple procedure. Tools can be tested in all inclinations (0-360º), toolface (0-360º) and azimuth angles (0-360º).

SERVICES

Gyro Wireline Services Limited instruments is a very simple procedure. Tools can be tested in all inclinations operate with the latest Generation tools (GyroTracer Directional™ North Seeking) in high-speed continuous gyro surveying. The GyroTracer Directional™ surveys the wellbore in continuous mode at speeds of up to 492 ft/min while simultaneously sending data to the surface equipment in both wireline and memory mode.
GyroTracer Directional accurately survey all well profiles from vertical to horizontal at high latitudes or inclinations with no accuracy degradation (Inclination accuracy +/- 0.1˚- Azimuth accuracy 0.1% (subject to well profile)).
The tool is one of the most all-round and versatile North Seeking Gyro tools on the market. Unlike other continuous gyro systems, the GyroTracer Directional™ does not require any surface alignment or surface calibration prior to survey.

The tool is one of the most all-round and versatile North Seeking Gyro tools on the market. Unlike other continuous gyro systems, the GyroTracer Directional™ does not require any surface alignment or surface calibration prior to survey.

We operate with highly accurate, extremely reliable downhole directional survey and orientation tool. Comprising of the latest technology, the GyroTracer™ system uses gyro compassing method to find direction with Inclination accuracy of +/- 0.1° and Azimuth accuracy of +/- 1.0°.

Gyro Wireline Services Limited Gyro tools can be dropped in the wellbore and pulled out with the drill string. No “Pump Down” is required. No monel drill collar is necessary and the tool can survey through the cased section of the well as it is not dependent on the magnetic field. The solid state construction of the instrument makes the gyro more rugged than any mechanical drop gyro available, dropped tool is then retrieved at the surface or ties in point and downloaded for immediate results.

Gyro Wireline Services Limited system can be run in a variety of applications from shallow to deep borehole, slim hole, whip stock, motor kickoff or any other Jetting systems, we can orient down-hole system in both single or in multi shot mode with Gravity toolface accuracy of +/- 0.1° and Gyroscopic toolface accuracy of +/- 1.0°.
