Inclination

What Does Inclination Mean?

Inclination, in the context of trenchless technology, is the degree of slope that a wellbore is designed to proceed in. It is the angle of the wellbore defined by a vertical line and a tangent line. When using horizontal directional drilling (HDD), the drill head for constructing the pilot bore is launched at an angle from the ground surface. The drill head is monitored constantly to measure the inclination and ensure minimum deviation from the planned bore path.

Trenchlesspedia Explains Inclination

During the construction of the pilot bore, walkover guidance systems are used regularly. The sonde placed inside the drill head transmits electromagnetic signals that are used to track the progress of the drill head. The results are displayed on a monitor as the walkover proceeds. The constant monitoring ensures that the drill head does not deviate from the planned bore path unless so advised by the drill operator when soil conditions contrary to investigation reports are encountered. Measuring inclination is an important part of the drilling process and must be constantly monitored.
