On the face of it, the process of mining seems like a huge undertaking, with ginormous machines required to cut equally massive tunnels through the Earth in order to extract the precious metals or oil within. In fact however, whilst drilling machines are an important part of mining, a much smaller machine is equally vital. Precision is absolutely key in this business, and in order for these drilling machines to know exactly where to go, a downhole measurement tool is required. One of the most accurate devices in this sector is the North Seeking Gyro, a device which can find true north from any location, using gyro compassing technology.
A huge benefit of the North Seeking Gyro for the mining, oil and gas industry is these devices do not use a magnetic sensor, this means they are not affected by magnetic interference and can be placed alongside metal casing and drill pipe without sacrificing accuracy. Due to this obvious advantage, the North Seeking Gyro is considered the best tool for downhole measurement.
