Field Developments and ChallengesWith few exceptions subsea oil fields have up to nowbeen flowing by their own pressure and/or assisted bypressure maintenance such as water/gas injection andto some extent gas liftThe new challenges:• Deeper water• Heavier oil• Less productive reservoirs• Low pressure/extreme high pressure• Flow assurance challenges• Increased tie-backs/tie-backs of remote satellites• Maturing of 1 st generation subsea fields• Reservoir uncertainties and low recovery factorCopyright Framo Engineering 2011

Benefits of Subsea BoostingIncreased Production and Recovery• Accelerated and prolonged plateau production• Increased RecoveryTieback of Fields and Production Enabling• Well kick-off• Extended reach of remote fields and wellsFlexibility wrt Subsea Integration• Applicable for Green-fields as well as retrofit to Brown-fields• XT integrated to Freestanding Modules with well tie-ins, etcCommercially attractive solutions• Relative short payback time• Maintenance by ROV and light intervention vesselCopyright Framo Engineering 2011
IOR effect of Subsea BoostingThe well will flow at lower pressure• Weak wells can be produced together with strong wells• Weak wells can be produced for a longer period before dying• Weak/dead wells can be started with the pumps• More efficiently reservoir drainage when wells can flow at higher rate• More controlled drainageThe liquid production rate will be higher• Fields can be produced longer before critical low flow is present (slugging andcool-down problems)• Economical cut-off will be at a higher water-cutCopyright Framo Engineering 2011
