PDO for Luno II@Lundin

PDO for Luno II

Lundin Norway has submitted the PDO for the Solveig field (former Luno II discovery), a subsea tie-back to Edvard Grieg.

The Solveig oil discovery in PL359, is located 15 km south of the Edvard Grieg field and will be developed via a subsea tie-back to the Edvard Grieg platform, involving five development wells with gross peak production of 30 Mboepd and is anticipated to start up in the first quarter of 2021.

Lundin is operator with 65% working interest in PL 359 and submitted the plan for development and operation (PDO) to the Norwegian Ministry of Petroleum and Energy together with partners Wintershall (20%) and OMV (15%). Lundin acquired Equinor’s 15% interest in PL 359 in 2018 (read more in “NCS license swap”) and equalized hereby ownership interests in the Solveig and Edvard Grieg license.

Luno II

The reservoir of Luno II is in sandstone and conglomerate of predominantly Triassic age (Skagerrak Formation), formed in small basins along the southwestern flank of the South Utsira High. The reservoir contains oil with a small gas cap.

In 2018 Lundin drilled a Luno II appraisal well 16/4-11 in the B segment and encountered better quality sandstones than expected. The gross resources in Luno II were therefore increased from 30 to 80 MMboe up til 40-100 MMboe.

Solveig development

The Solveig development phase 1 contains 57 MMboe of gross proven plus probable reserves in segment B outer wedge and segment C. The development scheme involves three horizontal oil production wells and two water injection wells. The potential for further phases of development, which will capture the upside potential in the discovered resources, will be derisked by production performance from phase 1.

The Solveig project will be implemented together with the Rolvsnes Extended Well Test (EWT) project to take advantage of contracting and implementation synergies. Lundin needs more tie-backs to Edvard Grieg and is therefore planning an Extended Well Test on Rolvsnes to address the remaining uncertainties after a successful horizontal appraisal well in fractured basement reservoirs. An exploration well on another potential tie-back to Edvard Gried: the fractured basement prospect Goddo is expected to be drilled in May or June 2019.
