石油设备网讯 据Oil & Gas Journal网站3月19日休斯顿报道 Spirit能源及其合作伙伴于3月16日在北海405号生产许可证的Ula油田以东13公里处的Oda油田开始石油生产，比计划提前了约5个月。
Spirit针对Oda油田的计划于2017年获得批准，计划要求通过海底设施进行开发，包括两口与Ula油田相连的生产井进行处理以及一口注入井提供压力支持（OGJ，2016年11月30日报道）。石油出口到科菲斯克（Ekofisk），然后由Norpipe运往英国Teesside终端。将来自Oda的天然气注入Ula储层，以提高该油田的采收率，处理设备和连接到Ula平台的连接设备将重复使用，该设备来自已关停的Oselvar油田。
2011年通过8/10-4S井发现Oda的主储层在Ula晚侏罗世砂岩中含有石油，该储层位于2900米的海底，呈陡峭倾斜，质量良好。
在Oda项目启动之前，Spirit能源与四家供应商公司签订了长期合同：Aibel、Subea 7、TechnipFMC和DNV GL。
Oda油田可采储量估计约为3300万桶油当量，其中95%是石油，最高产量预计将达到近3.5万桶/日。
Spirit拥有40%的运营权益，其他许可证持有人为挪威Suncor能源（30%），挪威Faroe石油（15%）和Aker BP ASA（15%）。

Spirit starts production from Oda field in North Sea
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%.
