While C02 injected for EOR may well stay below ground permanently, this is not necessarily the case, and C02 injected for EOR is not considered permanently stored in the UNFCCC national inventory reporting system. The available UNFCCC national inventory statistics do not allow us to differentiate fully between C02 that is released from on-site natural gas processing as in Sleipner and Snah-vit, and C02 from other production-related processes or from natural gas processing at a downstream processing facility. Since parts of the latter may be a mix of processes that are analogous to the capture of admixed C02 which is done at Sleipner and Snah-vit, and processes that are not, we calculate four different scaled abatement potentials based on different assumptions about which UNFCCC figures to include, and on whether to include both oil and gas production or gas production only. All are still at the testing stage and not operating at a significant scale.
