Directional Boring

Directional Boring

Directional drilling is an essential component in many major construction projects. Gas lines, oil pipelines, water lines, sewer lines, and communications/fiber optic lines all require directional drilling services. Whether the service is contracted by a government agency, gas company, oil company, water contractor, pipeline contractor, or municipality, Southeast Directional Drilling is standing by to answer your questions and to submit a bid for your directional drilling requirements.

The importance of high quality directional drilling can’t be overstated. The problem is that most people don’t have a thorough understanding of the directional drilling process. To help give you a better idea what directional drilling entails, here is a very brief look at a typical directional drilling project. It generally begins with a pilot hole. The pilot hole is a narrow opening down the length of the crossing. Once the pilot hole has been completed, the tunnel can be enlarged.

The hole enlargement process is called reaming, whereby the pilot hole is “reamed out” to create a larger tunnel. Done in several stages, each reaming clears the hole out a little more until it reaches its planned dimensions. The initial pilot hole of about 10 inches would be reamed out in three to five passes until it reaches its planned dimensions of 42 inches, for example.

Once the hole is reamed out, a final pass called a mud pass is performed. This clears the hole of any unwanted debris and prepares it for the final stage where the pipeline is pulled back. Once the pipeline is pulled into the reamed and cleaned hole, clean up ensues.

Southeast Directional Drilling Prepared for All Soil Conditions

SEDD-article After years of preparation, work on the Northern Natural Gas (NNG) Cedar Station Upgrade in Dakota County, Minnesota (US), was completed in the autumn of 2019. Approximately eight miles (12.9 km) of 20 in. (50.8 cm) steel pipeline was installed around the Twin Cities suburb of Eagan.
