David Willoughby Will Present “Horizontal  Directional Drilling for Pipelines Feasibility Workshop,” as a Webinar on January 7, 2021, at 9 am CST.

This training has the minimum required to hold the class. Further information to be provided upon registration.

Course Description

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.

After presenting and discussing the surface and subsurface feasibility concerns, we will look at and discuss a couple of real-world project feasibility studies and reports.

This three-hour webinar will cover the following topics:

1.   HDD Feasibility
2.   Surface Conditions Feasibility Concerns
3.   Subsurface Conditions Feasibility Concerns
4.  Review and Discuss Real World HDD Feasibility Study and Report

Participants will receive a Certificate of Completion awarding 3 PDHs

Feedback:

“Good, informative presentation. Thank you.”
“David operated well on the fly. He was able to extend the talk with useful information when time allowed at the end. He  handled questions well even when they jumped back to prior topics.”
“Very knowledgable.”
“Really appreciated Mr. Willoughby’s willingness to offer rules of thumb and examples.”
“I like how he marked up slides to reinforce points. You don’t see that often.”
“Instructor was clear and easy to understand – I did like the slide deck.”

David A. Willoughby, RK&K Director, Energy & Corrosion (ret)

Mr. Willoughby has 40 years of experience in engineering, pipeline design, corrosion control, and management in the petroleum and utilities pipeline industry. His experience includes gas transmission and distribution systems, petroleum facilities, and water/sewer pipelines from conception through design, construction and testing, economic evaluation, and project field supervision. Mr. Willoughby has been responsible for the design, permitting, inspection, and construction administration of numerous horizontal directional drills (HDD) on pipeline projects. Mr. Willoughby is author of several articles and two books published by McGraw-Hill; Plastic Piping Handbook, 2002 and Horizontal Directional Drilling, 2005.

Mr. Willoughby provides HDD training to the pipeline and utility industries. He has presented HDD training to the engineering workshop at the N.C. Utilities Commission Office of Pipeline Safety Conference, Southern Gas Association Annual Conference and teaches several HDD programs a year for a broad list of clients such as Equitable Resources, Dominion Energy, FERC, National Gas Company of Trinidad, Public Service of NC, Exxon Pipeline, Shell Oil, Atlanta Gas and Light, Dominion Transmission, Columbia Gas Transmission, Colonial Pipeline, Questar Gas Company, Kansas Gas Services, HT Engineering, etc. Mr. Willoughby’s HDD training is used to provide Professional Development Hours (PDU) for professional engineers in many states, including Texas.
