Directional Drilling: Everything You Ever Wanted To Know ...

What is directional drilling? Directional drilling is a broad term used to describe any boring that doesn’t go in a straight line vertically down. In fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path.

Design Radius of Curvature - Horizontal Directional Drilling
Design Radius of Curvature - Horizontal Directional Drilling

The largest bend radius of either the drill rod or product pipe is the number that must be used for planning and completing the bore. A common industry standard for determining the design radius of curvature for bends used in HDD installations is to multiply the nominal diameter of the pipe in inches by 100 to determine the, allowable radi,us in feet.

Bend radius must be calculated for with, any directional drilling, pipe installation project. During the installation of pipeline products, the pipe experiences a combination of tensile, bending, and compressive stresses. Every type of pipe has its breaking point and steering clear of damaging pipe can be accomplished if the right steps are taken.
