Lundin Energy has commenced production from the extended well test (EWT) at the Rolvsnes field in the Norwegian North Sea.
Located in production license (PL) 338C on the southern side of the Edvard Grieg field, the Rolvsnes oil discovery is a fractured and weathered granite basement reservoir.
In 2018, a horizontal appraisal well was successfully drilled at the field that flowed 7,000 barrels of oil per day (bopd) and demonstrated good reservoir productivity.
The drilling resulted in an increase in the resource range of the Rolvsnes discovery.
As a result, the partners intended to conduct the Rolvsnes extended well test through a tie-back of the existing Rolvsnes horizontal well to the Edvard Grieg platform.
As per estimates, the Rolvsnes field holds resources between 14 and 78 million barrels of oil equivalent (MMboe) gross.
Lundin said that the EWT is intended to assess the reservoir properties, reservoir connectivity and the field’s production performance.
If successful, the firm expects the test to have the potential to unlock a full field development for Rolvsnes, while further extending the Edvard Grieg production period.
The firm also anticipates the successful test to de-risk significant additional resource potential in basement reservoirs on the Utsira High.
Lundin plans to submit a plan for the development and operation for the Rolvsnes field by the end of 2022.
Lundin Energy president and CEO Nick Walker said: “One of our strategic priorities is to extend plateau production on Edvard Grieg keeping the facilities full in the long term.
“The Rolvsnes EWT is the first tie-back development into our operated Edvard Grieg hub and production data from the EWT will provide vital information to potentially unlock the full field development of the Rolvsnes field, as well as further weathered and fractured basement reservoir opportunities on the Utsira High.”
Lundin Energy Norway, a subsidiary of Lundin Energy, operates the PL338C with a 80% stake, while the remaining interest is owned by OMV (Norge).
