Bailey Theriault is a Senior Principal Geologist based in New Hampshire with more than 14 years of experience focused on geohazard assessment and management for oil and gas clients.
Bailey assists clients as the technical lead for projects focused on identifying, assessing, mitigating, and monitoring geologic conditions and hazards along pipelines for major oil and gas pipeline operators in the United States and Canada. Bailey has managed a variety of large, long-term, and ongoing geohazard programs for pipeline operators, including clients such as Kinder Morgan, TC Energy, Enbridge, Shell Pipeline, and Tallgrass. These programs have typically included efforts to: develop and implement company geohazard programs and procedures; perform system-wide and local efforts to identify, assess, mitigate, and monitor geohazards; provide engineering design and construction oversight of pipeline mitigation projects; perform route assessments, root cause analyses, and geohazard risk assessments; develop and implement geohazard data management systems; and prepare and present geohazard training courses. Assessed geohazards have generally included landslides; subsidence related to mining, karst, and fluid withdrawal; seismic hazards including fault rupture, ground shaking, and liquefaction; hydrotechnical hazards; meteorological hazards; volcanic hazards; expansive/collapsible soils; frost heave; permafrost; and acid rock drainage.
To advance the state of the practice, Bailey participates in industry groups such as the Pipeline Research Council International (PRCI) and the Interstate Natural Gas Association of America (INGAA) where she has participated in research and presented on a variety of geohazard management topics, including the use of ILI IMU data, LiDAR data, and InSAR data for regional-scale geohazard identification and monitoring. Bailey was a lead author on the recently completed INGAA Joint Industry Project (JIP) on management of landslide hazards for pipelines.
