Spirit Energy Ltd. and its partners started oil production from Oda field, which lies in 65 m of water 13 km east of Ula in production license 405 in the North Sea, on Mar. 16, about 5 months ahead of schedule.
Spirit’s plan for Oda, which was approved in 2017, calls for development via a subsea facility including two production wells tied back to Ula field for processing and one injection well for pressure support (OGJ Online, Nov. 30, 2016). Oil is exported to Ekofisk and then carried by Norpipe to the UK’s Teesside terminal. Gas from Oda is injected into the Ula reservoir to improve oil recovery from that field. The processing equipment and hook-up to the Ula platform are reused from the shutdown Oselvar field.
Discovered in 2011 via well 8/10-4S, Oda’s main reservoir contains oil in sandstone of Late Jurassic age in the Ula formation. The reservoir, 2,900 m subsea, is steeply dipping and quality is good.
Prior to start-up of the Oda project, Spirit Energy entered into long-term contracts with four supplier companies: Aibel, Subsea 7, TechnipFMC, and DNV GL.
Oda’s recoverable reserves are estimated at about 33 million boe, of which 95% is oil. Peak production is expected to reach nearly 35,000 b/d.
Spirit is operator with 40%. Other licensees are Suncor Energy Norge AS 30%, Faroe Petroleum Norge AS 15%, and Aker BP ASA 15%.
