Horizontal directional drilling (HDD) has now become the preferred method of installation for the majority of the pipeline and cable crossings installed in the United States. The advantages of installation are widely accepted and include better economics, shorter installation times and substantially reduced environmental impact compared to conventional dredging construction. The techniques for installation have been continually improved and downhole survey accuracy has become extremely accurate allowing for closer tolerance installations. In short, an industry that had its roots in the early 1970s has now grown to be an accepted standard for the construction industry. The utilization of horizontal wells for soil and groundwater remediation was a natural evolution from the original crossing applications utilizing HDD. Horizontal wells utilized in the proper locations could offer significant advantages over conventional vertical well applications. As technical personnel in the remediation field are increasingly exposed to the installation advantages, you will see many new applications being undertaken. The following are areas where HDD well installation are most cost effective and offer significant advantages to conventional vertical well installation and operation.
