TRANSCRIPT
Spectra Energy’s Fort Nelson CCS Feasibility Project
University ofNorth Dakota
Grand Forks
Drill rig and camp site near Fort Nelson, British Columbia, Canada
Projected to be one of the largest CCS projects in the world.
Spectra Energy is proactively addressing subsurface risk as part of the technical and feasibility assessment phase by implementing a comprehensive risk management framework.
