Measurement while drilling (MWD)

Drilling with measurement while drilling, also called logging while drilling, works as follows. An instrument is placed behind the drill head that continuously performs measurements. This underground obtained data is transmitted to a computer. By analyzing this data, the rig operator always knows exactly where the drill head is and how to make any necessary adjustments.

Measurement while drilling instruments can measure various variables, such as the depth of the drill head, the distance from the entry point, the direction in pitch and azimuth of the drill head, underground temperature and pressure, both in the borehole and within the drill rods. This data enables accurate underground drilling.

Brownline has developed the Drillguide Gyro Steering Tool: a leading measurement while drilling instrument that provides insight into all relevant drilling parameters. The Drillguide GST transmits its measurements via a cable connection to our control system, where the data is processed and shared with the rig operator on a shared display.

The interface that the rig operator sees is highly user-friendly. With our in-house developed algorithms, the position and direction of the drill head are determined very accurately. With an accuracy of 0.01° in pitch and 0.04° in azimuth, the Drillguide GST is the most accurate measurement while drilling tool in the world. This level of precision results in a maximum deviation of only 7 cm per 100 drilled meters.

Thanks to the very high frequency at which data is transmitted, the position of the drill head can be monitored in real time. This enables the operator to steer with unparalleled accuracy and ensures an extremely smooth and consistent bore path. In addition, the Pressure-While-Drilling module integrated into the Drillguide GST provides the rig operator with accurate insight into the pressure measured inside the borehole.
