David Willoughby will present  “Horizontal Directional Drilling – Coverage of HDD Technology for Utility and Pipeline Application”  as a live webinar on October 19, 20, 2021


The Horizontal Directional Drilling webinar is offered as a 13 hour webinar that covers Horizontal Directional Drilling (HDD) feasibility analysis and design. This webinar provides technical information on HDD equipment, design, product pipe stress analysis, and construction techniques. The course is geared to provide the student with a thorough knowledge of the HDD basics and transition to an in-depth overview of HDD feasibility and design. A key aspect of HDD design is determining if crossing an obstacle by HDD is technically feasible.  That is, can the proposed crossing be installed using today’s tools and techniques? Technical feasibility is demonstrated primarily by comparing the proposed crossing with previously completed installations.

There are many factors to consider when evaluating the technical feasibility of an HDD project. Conducting a site survey, usually the first step, is important for all HDD projects and is a significant part of the HDD site characterization. The site survey should include both surface and some level of subsurface investigations. This webinar will cover the basic tasks from a site survey. We will discuss information related to the surface and subsurface feasibility concerns. We will discuss how existing features, both natural and man-made, can impact the way an HDD crossing is configured. We will discuss how the subsurface conditions can impact the various phases of the HDD construction. We will look at the key characteristics such as earth material types, stratification, and groundwater conditions. Also included are the various aspects of the site’s surface such as the topographic/hydrographic relief and the presence of human activities.

Due to an increasing focus on minimizing environmental impact, it has become standard practice in the HDD industry to evaluate the potential for drilling fluid to inadvertently flow to the surface due to hydro fracture. We discuss methods for evaluating the risk of inadvertent returns due to hydro fracture by comparing the confining capacity of the soils overlying the drilled path to the annular pressure necessary to conduct HDD operations. The course focus will be on HDD with steel and plastic pipelines. The webinar includes design calculations with examples.

We will also include demonstrations of the applicable HDD PowerTool (HDDPT) Modules.

This 12-hour course will be held in two 6.5-hour sessions:
October 19, 2021 – 8 a.m. – 2:30  CST
October 20, 2021 – 8 a.m. – 2:30 CST
