据俄罗斯油气网7月30日奥斯陆报道，韦斯特伍德全球能源公司（ Westwood Global Energy）报告称，截至7月28日，挪威有2口勘探井和1口评价井处于钻井状态。
7月份的关键井包括Stovegolvet和Stangnestind井的边界远景区测试，这两口井都已完钻。
今年迄今为止，挪威共完钻17口勘探井，其中7口勘探井获得了商业油气发现，商业油气发现成功率为41%。
北海
Equinor和道达尔公司的31/11-1 S Stovegolvet勘探井在6月28日完成钻井作业。
此井位于北海北部的Stord盆地，是下侏罗纪高风险的边界测试井，与最近井的距离也超过30公里。
这口井未能发现碳氢化合物，作为一口干井被放弃。
然而，在主要目标Johansen组和次要目标上侏罗纪Sognefjord组和中侏罗纪Fensfjord/Krossfjord组均成功钻穿了储油层优质砂岩。
由于缺少碳氢化合物，该井的失败主要是由于该地区缺乏来源或没有充注到结构中。
该井的钻探还评估了储集层的二氧化碳储量。
同样在今年7月，奥地利油气集团的1/3-13 Ommadawn井(未商业石油发现)和匈牙利油气集团的25/8-22 S living评价井(结果待定)的钻井作业也已完成。
伦丁石油公司的16/1-34 S Lille Prinsen评价井在7月7日开钻，而温特斯豪DEA的31/4-A-1井在6月21日开始首次侧钻以后在7月20日开始第2次侧钻，第2次侧钻的目标是塔里斯科东远景构造。
挪威海
6月，德国温特斯豪DEA的6406/3-10 Bergknapp发现井重新进入以完成数据采集，包括中途测试，但由于Covid-19和相关限制，无法在发现井中进行中途测试。
此井随后于7月14日进行了侧钻作业，截至撰写本文时，侧钻作业仍在进行中。
巴伦支海
阿克尔 BP的7234/6-1 stannestind勘探井在7月19日完成钻井作业。
这口位于第23轮探区包销承诺的勘探井是一次非常高风险区域规模巨大圈闭结构的边界测试，该区域一直延伸到俄罗斯，目标是二叠纪-石炭系Orn组。
该井在目标地层中钻遇到了187英尺高的CO2含量气柱，其中85英尺由白云岩组成，储层质量较差或中等。
这个位置的600 - 750亿立方英尺的资源是非商业性的，然而，这口井在Fedynsky High成功地验证了一个可行的石油系统。

Norway records 7 commercial discoveries in year to date
Westwood Global Energy reports that there were 2 exploration and 1 appraisal wells active as of July 28.
Key wells in July include frontier play tests at Stovegolvet and Stangnestind, both of which completed.
A total of 17 exploration wells have completed to date in 2021, from which 7 commercial discoveries have been made giving a 41% commercial success rate to date.
North Sea
Operations at Equinor and Total’s 31/11-1 S Stovegolvet exploration well were completed on June 28.
The well is located in the Stord Basin of the northern North Sea and was a high risk, frontier test of the Lower Jurassic, with the nearest well more than 30 km away.
The well failed to find hydrocarbons and was abandoned as a dry hole.
However, it was successful in penetrating reservoir quality sandstones in the primary objective Johansen Formation and in the secondary objective Upper Jurassic Sognefjord and Middle Jurassic Fensfjord/Krossfjord Formations.
Given the lack of hydrocarbons, the well appears to have failed primarily due to a lack of source in the area or charge into the structure.
The well was also drilled to assess reservoir properties with respect to CO2 storage.
Also in July, operations completed at OMV’s 1/3-13 Ommadawn well (non-commercial oil discovery) and MOL’s 25/8-22 S Iving appraisal well (result pending).
Drilling commenced at Lundin’s 16/1-34 S Lille Prinsen appraisal well on July 7 and a 2nd exploration sidetrack from Wintershall DEA’s 31/4-A-1 well, targeting the Talisker East prospect, was kicked-off on July 20, following the 1stsidetrack which commenced on June 21.
Norwegian Sea
In June, Wintershall DEA’s 6406/3-10 Bergknapp discovery well was re-entered to complete data acquisition, including a DST, that was unable to be performed in the discovery well due to Covid-19 and associated restrictions.
The well was subsequently sidetracked on July 14 and operations on this were ongoing at the time of writing.
Barents Sea
Operations on Aker BP’s 7234/6-1 Stangnestind exploration well completed on July 19.
The well, a firm commitment on 23rd round acreage, was a very high risk, frontier test of a regional scale mega-closure which extends into Russia and targeted the Permian – Carboniferous Orn Formation.
The well encountered a 187ft, high CO2 content gas column in the target formation, 85ft of which comprised dolomites with poor to moderate reservoir quality.
Resources of 60-75 bcf are non-commercial at this location, however the well was successful in proving a working petroleum system on the Fedynsky High.
