Environmental Risk Assessment (ERA) of IOR solutions on the Norwegian Continental Shelf


The National IOR Centre of Norway, environmental risk assessment, ERA, IOR, increased oil recovery, EOR, enhanced oil recovery


The aim of the Environmental Risk Assessment (ERA) work at the IOR Centre is to provide methods, procedures, and key data to enable assessment of environmental risk in relation to IOR solutions (products and processes) elaborated at the center.

The objective of this report is to provide a user guidance summary on methods and tools to conduct ERA related to different IOR solutions. It will explain workflows, expertise, and tools needed in relation to different types of IOR solutions applied.

The report is foremost addressed to environmental engineers in the oil and gas industry, but will also be relevant for environmental managers, environmental authorities and regulators as well as for suppliers of chemical products and environmental services.
