Brownline has developed a downhole steering system based on gyro technology. The Gyro Steering Tool provides highly accurate navigational information of the drill head in real time. In doing so, it is not affected by any external influences. The steering tool is currently the most advanced steering tool available in the world!
How the Gyro Steering Tool works
The Gyro Steering Tool is the basis for our steering services. The tool is mounted behind the jetting assembly/ mud motor. The downhole unit measures the position of the steering tool in real time ("Measurement-whilst-drilling"). This information is combined with the drilled length to calculate the displacement through our proprietary algorithms. With this, the drill head can thereby be accurately steered over the envisaged bore path.
The most advanced steering tool
Our innovative Gyro Steering Tool provides a proven accuracy of 0.01º in the pitch plane and 0.04º in the azimuth plane, irrespective of the circumstances. The Gyro steering tool is not dependent on magnetic fields or beacons and hence has a (much) shorter setup time. This saves our customers time and resources.
With our Gyro Steering Tool drills are realised with the highest precision.
Additionally, the GST is equipped with our Pressure-While-Drilling (PWD) module. Using built-in pressure sensors, the tool measures the mud pressure in the borehole as well as the inner pressure. Careful real-time monitoring of the borehole pressure reduces the risk of inadvertent returns or blowouts, which is especially important when drilling in environmentally sensitive areas, but also in busy urban environments.
