The Directional Boring Advantage Archived 2022-08-16 at the Wayback Machine describes techniques used, with diagrams. Directional Boring provides examples of the six types of utilities installed via the directional boring method. Directional Boring provides details about the various types of Horizontal directional drill machines available.
Mud pump (#4) is a reciprocal type of pump used to circulate drilling fluid through the system. Mud tank (#1) is often called mud pits and stores drilling fluid until it is required down the wellbore. Setback (#17) is a part of the drill floor (#21) where the stands of drill pipe are stood upright. It is typically made of a metal frame ...
Directional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation directional drilling, directional boring (horizontal directional drilling - HDD), and surface in seam (SIS), which horizontally intersects a vertical bore ...
The ability to vary the directional tendency of the assembly comes from varying the weight on the bit. A fixed assembly has only one directional tendency. The weight on bit allows you to tune that tendency. The bottom-hole assembly (BHA) can be: slick with no stabilisers; a pendulum bottom-hole assembly for reducing the deviation of a well
The primary use of real-time surveys is in directional drilling. For the directional driller to steer the well towards a target zone, he must know where the well is going, and what the effects of his steering efforts are. [citation needed] MWD tools also generally provide toolface measurements to aid in directional drilling using downhole mud ...
They are generally programmed by the measurement while drilling (MWD) engineer or directional driller who transmits commands using surface equipment (typically using either pressure fluctuations in the mud column or variations in the drill string rotation) which the tool responds to, and gradually steers into the desired direction.

Trenchless construction includes such construction methods as tunneling, microtunneling (MTM), horizontal directional drilling (HDD) also known as directional boring, pipe ramming (PR), pipe jacking (PJ), moling, horizontal auger boring (HAB) and other methods for the installation of pipelines and cables below the ground with minimal excavation.
