據(jù)俄羅斯油氣網(wǎng)7月30日奧斯陸報道，韋斯特伍德全球能源公司（ Westwood Global Energy）報告稱，截至7月28日，挪威有2口勘探井和1口評價井處于鉆井狀態(tài)。
7月份的關(guān)鍵井包括Stovegolvet和Stangnestind井的邊界遠景區(qū)測試，這兩口井都已完鉆。
今年迄今為止，挪威共完鉆17口勘探井，其中7口勘探井獲得了商業(yè)油氣發(fā)現(xiàn)，商業(yè)油氣發(fā)現(xiàn)成功率為41%。
北海
Equinor和道達爾公司的31/11-1 S Stovegolvet勘探井在6月28日完成鉆井作業(yè)。
此井位于北海北部的Stord盆地，是下侏羅紀高風險的邊界測試井，與最近井的距離也超過30公里。
這口井未能發(fā)現(xiàn)碳氫化合物，作為一口干井被放棄。
然而，在主要目標Johansen組和次要目標上侏羅紀Sognefjord組和中侏羅紀Fensfjord/Krossfjord組均成功鉆穿了儲油層優(yōu)質(zhì)砂巖。
由于缺少碳氫化合物，該井的失敗主要是由于該地區(qū)缺乏來源或沒有充注到結(jié)構(gòu)中。
該井的鉆探還評估了儲集層的二氧化碳儲量。
同樣在今年7月，奧地利油氣集團的1/3-13 Ommadawn井(未商業(yè)石油發(fā)現(xiàn))和匈牙利油氣集團的25/8-22 S living評價井(結(jié)果待定)的鉆井作業(yè)也已完成。
倫丁石油公司的16/1-34 S Lille Prinsen評價井在7月7日開鉆，而溫特斯豪DEA的31/4-A-1井在6月21日開始首次側(cè)鉆以后在7月20日開始第2次側(cè)鉆，第2次側(cè)鉆的目標是塔里斯科東遠景構(gòu)造。
挪威海
6月，德國溫特斯豪DEA的6406/3-10 Bergknapp發(fā)現(xiàn)井重新進入以完成數(shù)據(jù)采集，包括中途測試，但由于Covid-19和相關(guān)限制，無法在發(fā)現(xiàn)井中進行中途測試。
此井隨后于7月14日進行了側(cè)鉆作業(yè)，截至撰寫本文時，側(cè)鉆作業(yè)仍在進行中。
巴倫支海
阿克爾 BP的7234/6-1 stannestind勘探井在7月19日完成鉆井作業(yè)。
這口位于第23輪探區(qū)包銷承諾的勘探井是一次非常高風險區(qū)域規(guī)模巨大圈閉結(jié)構(gòu)的邊界測試，該區(qū)域一直延伸到俄羅斯，目標是二疊紀-石炭系Orn組。
該井在目標地層中鉆遇到了187英尺高的CO2含量氣柱，其中85英尺由白云巖組成，儲層質(zhì)量較差或中等。
這個位置的600 - 750億立方英尺的資源是非商業(yè)性的，然而，這口井在Fedynsky High成功地驗證了一個可行的石油系統(tǒng)。

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.
