STOCKHOLM, Sweden – Lundin Norway has committed to an extended well test (EWT) on the Rolvsnes oil discovery on the Utsira High in the central Norwegian North Sea.
Rolvsnes is in license PL338C on the southern side of the Edvard Grieg field and is a fractured and weathered granite basement reservoir.
During drilling and testing last summer, a horizontal appraisal well (16/1-28) flowed 7,000 b/d. As a result, Lundin increased its resource estimate for the structure to 14-78 MMboe.
The EWT will be through a 3-km (1.86-mi) subsea tieback of the existing Rolvsnes horizontal well to the Grieg platform, with first oil expected in spring 2021. The program will coincide with theSolveig subsea tieback to the same platform to provide contracting and implementation synergies.
Although basement reservoirs have not been developed in Norway, they have produced successfully elsewhere in the world. Lundin hopes the EWT will provide clarification on the reservoir’s likely long-term performance.
To further assess the potential of the basement trend in this area, the company will drill an exploration well later this year on the Goddo prospect in the adjacent PL815 license. It estimates prospective combined resources from Rolvsnes and Goddo at more than 250 MMboe.
Earlier this year Lundin agreed to acquireLime Petroleum’s interest in the Rolvsnes/Goddo area. Following closure of the deal, anticipated in mid-year, the company will have an 80% operated stake in PLs 338C/338E, with the remainder held by OMV.
In PL815 (Goddo) Lundin will operate with a 60% stake, in partnership with Concedo and Petoro.
