Subsea Smart Multilateral Wells Increase Reserves at Gullfaks South Statfjord

Production from the Statfjord formation in Gullfaks South (GS) field was limited by low connectivity, reservoir heterogeneity, and gas breakthrough. Surface-operated downhole inflow control and multilateral wells were identified as solutions to these limitations. Implementing a downhole-instrumentation and -control system (DIACS) and multilateral technology (MLT) in three horizontal subsea wells led to a two-fold increase in the reserves estimate to 5.4x10^6 m^3 oil in the reservoir management plan for 2005.
