Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. Directional boring offers significant ...
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 ...
StraightLine HDD, formerly StraightLine Manufacturing, Inc., is an American corporation which designs and builds tooling and equipment for the Directional drilling industry. The company's products include directional drills, mud mixing systems, air hammers and a full line of down hole tools, wear parts and accessories for all brands of ...
Further reduction of friction is typically achieved with lubrication, and different types of bentonite and/or polymers can be used (as in horizontal directional boring) for this purpose. [5] Spoil removal from the pipe can be performed after the entire pipe is in place (shorter installations). If the pipe containing the spoil becomes too heavy ...
Logging while drilling (LWD) is a technique of conveying well logging tools into the well borehole downhole as part of the bottom hole assembly (BHA).. Although the terms Measurement while drilling (MWD) and LWD are related, within the context of this section, the term MWD refers to directional-drilling measurements, e.g., for decision support for the smooth operation of the drilling, while ...
The company operates across four major service areas: Drilling, Surveying, Wireline, and Support. Drilling Services encompasses a wide range of technologies designed for directional drilling applications, including performance motors, measurement-while-drilling (MWD) tools, rotary steerable systems (RSS), and gyro-while-drilling (GWD) tools, the latter of which was invented by Gyrodata in 2002 ...
Underground pneumatic boring is a trenchless method of installing underground utilities. The process creates an open-air chamber, referred to as a borehole . The borehole is then used to run utilities.
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 ...
