Pipeline Webinar Series Episode 9: Everything Old is New Again

Advancements in Hydraulic Fracture Analysis for HDD Applications with Dr. Ian Moore Recorded: September 27, 2023 Presenter: Trevor Hoyles, PE, Principal Engineer Moderator: Mark Miller, PE, Principal Engineer Special Guest: Dr. Ian Moore, PhD, PEng, Queen's University This webinar features a discussion on how cavity expansion theory originally developed in the 1960s, and sheds light on which models/equations should be used to estimate the maximum allowable annular drilling fluid pressures before hydrofracture or blowout will occur during horizontal directional drilling (HDD) operations. There have been numerous equations and models that have been developed for evaluating the risk of hydraulic fracture including the most widely known Delft equation. We will discuss how the Delft equation is used for evaluating hydraulic fracture potential in coarse-grained soils. Queen’s University has also presented alternative solutions for evaluating hydraulic fracture potential in fine-grained (clay) soils. Special Guest Dr. Ian Moore of Queen’s University joins the conversation about the latest advancements. Dr. Moore is a leading researcher in the field of trenchless technology and in particular hydraulic fracture analysis, and a Professor and Head Research Director for the Civil Engineering department at the GeoEngineering Centre at Queen's University in Kingston, Canada.
