Lundin Petroleum AB said its subsidiary, Lundin Norway AS, made two oil discoveries in exploration wells 16/1-31 S (Jorvik) and 16/1-31 A (Tellus East) on the eastern edge of Edvard Grieg field on Production License (PL) 338 on Utsira High.
Combined oil and natural gas gross resources were estimated in a range of 4-37 MMboe. Reserves from both discoveries can be developed with wells from the Edvard Grieg platform.
Jorvik encountered oil in 30 m of conglomerate reservoir of Triassic age with a thin sandstone above, Lundin Petroleum executives said.
The well flowed on test at around 130 b/d in the conglomerate interval. Pressure measurements show the area is in communication with Edvard Grieg field. This combination of conglomerate and sandstone reservoir types also exist on the southern and eastern parts of Edvard Grieg.
The Tellus East discovery involves a 60-m oil column in a porous, weathered basement reservoir.
The Tellus area, on the northern edge of Edvard Grieg field, already produces from two horizontal production wells. Lundin Petroleum executives said the Tellus East discovery provides them with more confidence in the basement potential from this part of Edvard Grieg field.
Crews drilled the dual branch Jorvik-Tellus East well 4 km northeast of the Edvard Grieg platform using the Leiv Eiriksson semisubmersible drilling rig. Lundin Norway operates PL338 with 65% working interest. Partners are OMV with 20% and Wintershall DEA with 15%.
Plans call for the Leiv Eiriksson rig to stay in the Utsira High area to drill numerous shallow gas pilot wells in the Solveig development project.
The rig will move to drill the Goddo exploration well 16/5-8S in PL815. Goddo will test the extension of the Rolvsnes weathered basement oil discovery into the adjacent license, where the combined area is estimated to contain gross potential resources of more than 250 MMboe.
Rolvsnes-Goddo, south of Edvard Grieg field, is targeting the same porous, weathered basement reservoir currently being produced from Edwad Grieg’s Tellus area. Lundin Norway operates PL815 with 60% working interest. Partners are Concedo and Petoro with 20% each.
