Course overview
**This is a previously recorded virtual training, now provided in on-demand format.**

In this training course, participants gain a comprehensive understanding of a crucial element in HDD design: the assessment of whether HDD methods can feasibly navigate obstacles using contemporary tools and techniques.

Technical feasibility is established through a comparative analysis between proposed crossings and past installations. This exploration delves into the multifaceted factors involved in evaluating the feasibility of an HDD project, with a particular focus on the initial site survey. This survey entails both surface and partial subsurface investigations, taking into account various factors, such as natural and man-made features, subsurface conditions, earth materials, stratification, groundwater, topography, and human activities.

Additionally, the course addresses the evaluation of the risk associated with inadvertent drilling fluid flow to the surface due to hydrofracture and offers insights from real-world feasibility studies.
