Measurement while drilling (MWD) tools

MWD tools are generally used for real-time directional borehole survey applications.

The tool uses accelerometers and magnetometers to measure the inclination and direction of the wellbore. The generated data is directly transmitted to the sur-face by using mud pulse technology. These measure-ments allow the determination of the wellbore path and position in the three-dimensional space.

We supply MWD systems in four sizes: 3 1⁄2", 4 3⁄4", 6 3⁄4" and 9 5⁄8".
