f Geophysics As a Tool for Pipeline Design in Challenging Terrain

Pipeline regulators are increasingly demanding more information from pipeline operators about ground conditions along proposed new pipeline routes. Pipelines are frequently routed through challenging and sensitive terrain. The two examples presented herein include watercourse crossings in mountainous terrain and alignments underlain by discontinuous permafrost. These areas require geotechnical investigations for pipeline design requirements; however, non-intrusive geophysics is a powerful and cost-effective tool that can be used to refine extensive drilling programs.
