Horizontal Drilling - an overview ScienceDirect Topics

Horizontal drilling is a special form of directional drilling. It involves drilling a well through a formation at well inclination of 90° from vertical. The long laterals of the well increase reservoir–well contact, thereby improving reservoir productivity.

8.1 Definition. Horizontal drilling is a process of directing a bit to drill along a horizontal path oriented approximately 85 to 95° from a vertical direction, whereas multilateral drilling is a process of drilling lateral holes from a main trunk such as horizontal, vertical, or directional (Fig. 13 ). Figure 13.

The Horizontal Directional Drilling Process

2015-8-6  The tools and techniques used in the horizontal directional drilling (HDD) process are an outgrowth of the oil well drilling industry. The components of a horizontal drilling rig used for pipeline construction are similar to those of an oil well drilling rig with the major exception being that a horizontal drilling rig is equipped with an inclined ramp as opposed to a vertical mast. HDD

What is Horizontal Drilling? (with pictures)

In horizontal drilling, workers start by going into the earth at a low angle, gradually increasing the angle to hit the target. They use flexible piping with a mud motor assembly. Instead of turning the entire length of pipe to rotate a drill bit, drilling mud is piped through the tubing to rotate a freely spinning head mounted at the end. This drill
