Lundin sanctions Rolvsnes extended well test project

Lundin Norway has agreed the final investment decision to proceed with an extended well test (EWT) on the Rolvsnes weathered and fractured basement discovery on the Utsira High off Norway. 

The Rolvsnes oil discovery is located in PL338C on the southern side of the Edvard Grieg field and is a fractured and weathered granite basement reservoir.

During 2018, the successful drilling and testing of a horizontal appraisal well (16/1-28) was completed, which flowed 7,000 bopd demonstrating good reservoir productivity and resulting in an increase in the Rolvsnes resource range, to between 14 and 78 MMboe gross.

Lundin said on Thursday that the Rolvsnes EWT will be conducted through a 3 km subsea tie-back of the existing Rolvsnes horizontal well to the Edvard Grieg platform, with first oil scheduled in the second quarter 2021. The project will be implemented together with the Solveig project to take advantage of contracting and implementation synergies. Lundin submitted the plan for the development of the Solveig field in late March.

First in Norway 

According to Lundin, this reservoir type has not previously been developed in Norway, although it has been developed successfully elsewhere in the world, and an EWT on Rolvsnes is required to better understand the long-term reservoir performance.

To further assess the potential of the basement trend on the Utsira High, an exploration well will be drilled on the Goddo prospect located in the adjacent PL815 license in 2019. The combined Rolvsnes and Goddo prospective area is estimated to contain gross potential resources of more than 250 MMboe.

The strategic acquisition of Lime Petroleum’s interest in the Rolvsnes/Goddo area was agreed in January 2019 and following completion of this acquisition, which is anticipated in mid-2019, Lundin Norway will hold an 80 percent operated working interest in PL338C/PL338E, with the remaining interest held by OMV. Further, in PL815 (Goddo) Lundin Norway will hold a 60 per cent operated working interest, with the partners Concedo and Petoro with 20 percent interest each.

Nick Walker, Chief Operating Officer of Lundin Petroleum, commented: “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 realize cost synergies and is another important step in extending the plateau production at the Greater Edvard Grieg Area.”
