HORIZONTAL DIRECTIONAL DRILLING

Horizontal directional drilling (HDD) is a type of drilling used to install underground utilities, such as pipe or cable. HDD involves using a small-diameter drill bit to bore a hole through the earth, then installing the utility through the hole.

HDD requires drilling mud, which is made of water, clay, and chemicals. The drilling mud is used to lubricate the drill bit and to keep the borehole from collapsing. The key ingredient in drilling mud is bentonite, which is a type of clay that expands when wet.

The drilling mud is pumped through the drill bit and out through the borehole. As the mud exits the borehole, it carries with it cuttings from the earth. These cuttings are returned to the surface, where they are removed from the mud.

Depending on the type of project, different drilling mud formulations may be used. DMD is a leading supplier of drilling mud and additives. Click here to learn about DMD’s bentonite drilling mud products.
