据海上工程师网报道，奥地利能源和石化公司（OMV）旗下的挪威分公司9月23日证实，该公司部署在挪威北海的Oswig勘探井日前获得了凝析油发现。
担任运营商的OMV挪威分公司表示，该公司和合作伙伴现在决定在这口发现井上另钻新孔，并进行中途测试（DST），合作伙伴Longboat能源公司表示，这口发现井可能是“挪威今年正在测试的最大天然气远景构造之一”。
Oswig勘探井的水下真实垂直深度为5003米，目标是塔伯特地层和内斯地层。塔伯特地层钻遇到了天然气和凝析油。在井位上，无法确定内斯地层深处是否存在碳氢化合物。
Longboat能源公司表示，Oswig勘探井由一个高压、高温的侏罗纪旋转断块组成，“钻前的无风险平均总资源量估计为9300万桶油当量”。
Longboat能源公司表示，值得肯定的钻井结果，以及从现有井眼收集全套井下动态数据的挑战，导致他们决定在发现井上另钻新孔并进行DST。
另钻新孔并进行DST将评估上塔伯特地层的产能，需要6-8周的时间完成，并需要得到监管部门的批准。
Longboat能源公司表示，已经在该区块上发现了几个额外的断块，这些断块可能包含8000万桶油当量的无风险平均资源，如果DST成功实施，将大大降低风险。
Longboat能源公司补充说，自2002年投产以来，位于发现井附近的Tune油田迄今已产1.4亿桶油当量。
OMV挪威分公司是该许可证的运营商，拥有40%的开采权益。 许可证合作伙伴为Source能源公司（20%）、温特斯豪Dea挪威公司（20%）和Longboat能源挪威分公司 （20%）。

OMV Confirms Find in One of "Largest Prospects in Norway"
The Norwegian arm of Austrian energy and petrochemicals company OMV has confirmed that the Oswig exploration well in the Norwegian North Sea has made a gas-condensate discovery.
OMV (Norge), as operator, said that it and its partners had now decided to drill a sidetrack and perform a drill stem test (DST) on the well, which partner Longboat says could be "one of the largest gas prospects being tested in Norway this year".
The well was drilled to a depth of 5,003 metres TVDSS targeting the Tarbert and Ness formations. Gas and condensate were encountered in the Tarbert Formation. Presence of hydrocarbons in the deeper Ness formation was inconclusive at the well location.
Partner Longboat Energy says Oswig consists of a high pressure, high temperature Jurassic rotated fault block "with a pre-drill gross unrisked mean resource of 93 mmboe".
It said that the positive result, as well as challenges collecting a full suite of downhole dynamic data from the existing well-bore led to the decision to sidetrack the well and perform the DST.
This will evaluate productivity of the Upper Tarbert Formation and will take 6-8 weeks to complete and is subject to regulatory approvals.
Longboat Energy said that several additional fault blocks have been identified on-block which could contain further gross unrisked mean resources of 80 mmboe which would be significantly derisked by a successful DST.
It added that the nearby Tune field has produced circa 140 mmboe since production commenced in 2002.
OMV (Norge) AS is the operator for the license with a 40 percent working interest. The license partners are Source Energy AS (20%), Wintershall Dea Norge AS (20%) and Longboat Energy Norge AS (20%).
