Evolution and Capabilities of HDD in Pipeline Installation
The pipeline drilling industry has seen tremendous growth in the past few decades, with advancements in rig technology and downhole tools. Horizontal Directional Drilling (HDD) now accommodates a wide range of pipeline sizes, from small pipes to large 60-inch diameter pipelines, and can cover distances up to 7,000 feet or more using advanced methods like intersect drilling. HDD can handle most soil conditions, including hard rock, although drilling in such materials can be slow and costly. Basic HDD components include the drill rig, guidance system, drilling fluids, and downhole tools.
