The Smørbukk South Extension is an improved oil recovery (IOR) project that has been developed by Statoil with a total investment of Nkr3.5bn ($424.8m). The project was sanctioned in 2013 and first production was achieved in September 2015.
The Smørbukk South Extension is part of the Åsgard oil field, which also consists of the Smørbukk and the Midgard discoveries. The Midgard discovery lies in blocks 6507/11 and 6407/2, whereas the Smørbukk and Smørbukk South discoveries lie in block 6506/11.
The Åsgard unit is operated by Statoil (34.57%) in partnership with Petoro (35.69%), Eni Norge (14.82%), Total E&P Norge (7.68%) and ExxonMobil (7.24%).
"The Smørbukk South Extension is part of the Åsgard oil field, which also consists of the Smørbukk and the Midgard discoveries."
Discovered in 1985, the Smørbukk South Extension was not economically viable to develop owing to its low-permeability. The existing infrastructure at the Åsgard field has been utilised now for planning and developing the project. The development is expected to add to the production from the Åsgard A FPSO in the future. The estimated life of the field is 12 years.
Reserves and reservoir details of Smørbukk South Extension
Recoverable reserves of the field are estimated to be 16.5m barrels of oil equivalent (mboe). The field comprises tight formations and contains hydrocarbons in reservoirs having varying porosities.
