Wireline Operator

Definition - What does Wireline Operator mean?

Wireline operator is one who operates the wireline that reads the azimuth and inclination of the borehole with the help of a magnetic guidance system. Special downhole instruments are lowered and raised as required and position of the drill head is logged by the operator.

Horizontal directional drilling (HDD) is a trenchless method that excavates below the earth's surface and needs correct guidance to prevent cross boring into other utility lines or deviating from the planned bore path.

Trenchlesspedia explains Wireline Operator

There are three methods of wireline steering in HDD - walkover, gyro and magnetic. While gyro is the latest technology in wireline steering, the most accurate is the magnetic wireliine steering because of its accuracy and reliability and the use of a coil further facilitates its steering capability.

A gyro always drills blind because it cannot be tracked. A wireline operator has the very important job of keeping the drill bit drilling in the right direction and tracking the tool face magnitude and orientation (TFMO).
