Assessment of Impact of SF(6) And PFCs Reservoir Tracers on Global Warming, Final Publishable Report

Project ID: ENK6-CT-2001-00501
Funded under: FP5-EESD


For several purposes related to reservoir characterisation and enhanced oil recovery, the oil production industry on the Norwegian Continental Shelf uses extensively and depends heavily on non-radioactive tracing substances like SF6 (sulphur hexafluoride) and PFCs (perfluorocarbons). However, these compounds, SF6 and PFCs, are potent greenhouse gases with very high global warming potential (GWP) and extremely long atmospheric lifetimes, resulting in their essentially irreversible accumulation in the atmosphere. Given (i) the current pressure of the environmental authorities on the oil industry to reduce and even ban the use of such chemicals and (ii) the proven usefulness of employing these substances in the oil exploration and production operations.
