When all of the data from the drill bit, collars, motors and the surface equipment enter the control panel, a complete representation occurs. Directional drilling is a broad term used to describe any boring that doesnt go in a straight line vertically down. Potholing also allows the tracker to visually observe the drill stem and drill head during drilling to ensure that the HDD machine operator avoids striking utility lines along the drill path. Pulling the reamer or product pipe through the bore hole too rapidly can also result in a surface heave. Welding Procedures. Hand signals are another option but a line of sight must be maintained and a set of pre-established signals must be established. I believe the article indicates about a mile or so, but I am not completely clear if this is accurate? Wow, I never knew that turbo drills and rotary steering drills are employed in directional situations mostly. HORIZONTAL DIRECTIONAL DRILLING- INSTALLATION PROCEDURE This technique involves drilling a pilot bore, generally along a closely defined shallow arc, and then, if necessary, enlarging the bore using a reamer or hole opener to create a bore large enough to accept the new PE100 pipe, which is generally pulled in behind a reamer. When a bore hole collapses, there is an immediate increase in rotary torque and pressure and a decrease or loss of circulation. HDD may be used where traditional vertical excavations are too hazardous, at sites with limited space, like dense, urban areas, and in industrial and residential areas.
