Horizontal Directional Drilling

Virtual, Instructor-Led

Event Summary

Join Trevor Hoyles and Urso Campos as they review horizontal directional drilling geometric design, hydraulic fracture analysis, and selected construction risks and considerations associated with groundwater intrusion and fat clay soils.

Learning Objectives

  • HDD geometry: Understand how to design horizontal directional drilling (HDD) geometry to comply with regulatory code while considering constructability. Focus on entry/exit angles, design radius, and tolerances. 

  • Hydraulic fracture analysis: Familiarize with advantages and disadvantages of traditional analytical methods (Delft) versus recently developed methods (such as Queen’s equation). Discuss the geotechnical soil parameters required for modeling and learn how to obtain them.  

  • Construction risks and considerations: Learn about groundwater intrusion and how to identify this hazard and mitigate risk. Know the challenges and mitigation for drilling in fat clay soils.  

Attendees will qualify for 1.75 Professional Development Hours (PDH) upon completion.

Who Should Attend

Construction Project Managers, Pipeline Engineers, Environmental Professionals, Safety Representatives, Routing, Procurement and Permitting Personnel of all levels of experience.


Meet the Instructors


Trevor Hoyles, P.E.

Principal Geological Engineer, GeoEngineers

Early in Trevor’s work life, he developed an interest in slope stabilization and landslide projects while working for timber companies and an Oregon-based natural gas pipeline company. From there, he built his career on helping pipeline companies manage natural hazard risks along existing pipelines and routing new pipelines to avoid those hazards.

Since joining GeoEngineers in 1998, Trevor has become a trusted advisor to pipeline companies throughout the United States, helping them manage geologic hazards risks and providing trenchless pipeline installation design services. Trevor also serves as a group manager for GeoEngineers’ pipelines business unit, developing business in the oil and gas market and managing large, multidisciplinary teams.

In 2015, Trevor started a new office in Raleigh, North Carolina. When he’s not visiting job sites or collaborating with his far-flung team members, Trevor loves to go camping with his family. His favorite recreational activities include mountain biking, hiking, and playing tennis with his wife and two boys.


Urso Campos, PhD

Project Engineer, GeoEngineers

Urso brings a wealth of practical and academic experience to his trenchless engineering work. Trenchless technology describes any method of installing underground pipeline without digging a conventional surface trench. Urso and his colleagues perform geotechnical explorations to characterize the soil, design installation plans, and analyze mechanical stresses and other hazards to the underground pipeline during and after construction.

“I like the combination of office and field work,” Urso says. “I like working in remote areas and being able to see the evolution of our work—from feasibility all the way to completing construction.”

It’s clear from his career that Urso is a lifelong learner who is willing to follow his curiosity wherever it leads. Urso has been an estimator for a demolition company, performed geotechnical lab testing, worked for an industrial roofing company and even taught engineering and mechanics of materials courses at Louisiana Tech University while working on his Ph.D. Urso also deepened his knowledge of trenchless technologies by partnering with the school’s industry-leading Trenchless Technology Center for his Ph.D. research on thin-walled press-fit interlocking joints and pipe stress analysis.

“I liked the combination of civil engineering and mechanical engineering,” Urso says. “I was very fortunate to find a job in which I could apply my education.”

That works out well, because GeoEngineers was also fortunate to find Urso. His experience, work ethic and dedication to technical excellence have been a great fit with our respected pipeline team.

“I like being a team player and am ready to help and assist in any way I can,” Urso says. “I tend to be that person who says yes to every request because I truly enjoy helping, learning, and being involved.”

Outside of his work responsibilities, Urso enjoys reading philosophy, history and trade journals. He stays active with soccer, running, hiking and backpacking—both nearby and abroad. Urso loves our National Parks but is also an accomplished world traveler with more than 40 countries in his passport! No matter how far away he goes, Urso is always happy to spend quality time at home with his wife and some home cooking.
