Subsea EOR
• CO2 injection
• WAG and SAWAG
• Polymerinjection
• Water with chemicals
• Low salinity water
• Use of tracers

Subsea EOR Operational Issues
• Difficult and costly access to subsea wells
• Large well spacing
• Manifolding of production and injection lines
• Sea water readily available – fresh water costly
• Logistic and pumping of water and chemicals
• Controlling of flow – sampling?
• Environmental effects?

Status
SubseaEOR
Way forward
• Subsea fields accounts for close to 50% of oil production on NCS
• IOR services ongoing
• EOR?
• Access to wells and cost a big issue
• Opportunities exists
• Technology available
• Pilots needed
• EOR initiative must come from the operators/NPD
• The subsea industry ready to act!
