Spectra Energy’s Fort Nelson CCS Feasibility Project University of North 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.
