OMV (Norge) AS will sidetrack and perform well tests on exploration well 30/5-4S Oswig after encountering hydrocarbons near Tune and Oseberg fields in the Norwegian North Sea.
The well, the first in production license (PL) 1100, is being drilled by the Maersk Intrepid jack-up rig in 95 m of water. The well was drilled to a vertical depth of 5,003 m below sea level.
The objective of the well was to prove hydrocarbons in the primary target of Jurassic Tarbert formation, with Jurassic Ness formation as secondary target. The well encountered gas and condensate in the Tarbert formation. Presence of hydrocarbons in the deeper Ness formation is inconclusive at the well site.
Extensive coring and logging data have been acquired in the well. Based on preliminary results, the PL 1100 license group decided to drill a sidetrack well and perform a drill stem test (DST). The key objective of the DST is to evaluate productivity of the Upper Tarbert formation and will take 6-8 weeks to complete. The well test is subject to regulatory approvals.
Oswig is one of the larger gas prospects being tested in Norway this year and several additional fault blocks have been identified within the license area. These prospects are estimated to contain further gross unrisked mean resources of 80 MMboe which would be significantly derisked by an Oswig discovery (OGJ Online Aug. 2, 2022).
OMV is operator at PL 1100 (40%) with partners Source Energy AS (20%), Wintershall DEA Norge AS (20%), and Longboat Energy Norge AS (20%).
