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.
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.
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 1st sidetrack which commenced on June 21.
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.
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.
