Swedish exploration and production company Lundin Petroleum has agreed the final investment decision on an extended well test on the Rolvsnes oil discovery, through its subsidiary Lundin Norway.
The Rolvsnes discovery is on the Utsira basement high, located in the PL338C licence on the southern side of the Edvard Grieg field.

Lundin Norway is the operator of the PL338 licence, with an operating interest of 50%. Its partners in the licence are Lime Petroleum (30%) and OMV (20%), and Lundin Norway is planning to complete acquisition of Lime Petroleum’s operating interest of PL338 in mid-2019.
A horizontal appraisal well was successfully drilled in 2018, which flowed 7,000 barrels of oil per day (bopd) and demonstrated good reservoir productivity. This resulted in an increase in the Rolvsnes resource range, which is between 17-78 million barrels of oil equivalent (Mboe) gross.
Drilling in the Rolvsnes prospect began in October 2015, with Lundin Norway discovering oil in December 2015.
The Rolvsnes extended well test will be conducted through a tie-back of the existing Rolvsnes horizontal well to the Edvard Grieg platform, with first oil scheduled for the second quarter (Q2) of 2021.

By GlobalDataAs this reservoir type has not been developed previously in Norway, the extended well test is required to gain a better understanding of the long-term reservoir performance.
An exploration well will also be drilled on the Goddo prospect located in the adjacent PL815 licence in 2019, to further assess the potential of the basement trend on the Utsira High. The gross potential resources of the combined Rolvsnes and Goddo prospective area are expected to be more than 250Mboe.
To take advantage of implementation and contracting synergies, the Rolvsnes project will be implemented with the Solveig oilfield project. A plan of development was submitted for the Solveig project in March 2019.
Lundin Petroleum chief operating officer Nick Walker said: “The sanction of an EWT on fractured and weathered basement is a first for the Norwegian Continental Shelf and a significant step forward for Lundin Petroleum as we look to unlock the significant resource potential, sitting right in between our Edvard Grieg platform and the giant Johan Sverdrup field.
“Coordinating this EWT with the Solveig tie-back development will realise cost synergies and is another important step in extending the plateau production at the Greater Edvard Grieg Area.”
