The Norwegian oil firm concluded the drilling of appraisal well 25/2-19 S and wildcat well 25/2-19 A in production licence 442.
Aker BP with a stake of 90.26% is the operator of production licence 442. Its partner in the block is Lotos Exploration and Production Norge which has a stake of 9.74%.
The wells, which were drilled, are located in the central part of the North Sea, nearly 200km northwest of Stavanger and 12km northeast of the Frøy oil field contained in production license 364.
The drilling was done by the Maersk Interceptor drilling facility, which will now head to drill development wells on the Tambar field, also operated by Aker BP.
According to Aker BP, the aim of the appraisal well was to delineate the oil discovery in the Delta structure in the north direction and assess the oil mobility in the Frigg formation.
The 25/2-19 S encountered a 13.5m oil column in sandstone with good reservoir quality, stated the Norwegian company.
On the other hand, the wildcat well 25/2-19 A’s primary and secondary exploration targets were to prove presence of petroleum in the Hugin and Sleipner formations.
Aker BP stated that the wildcat well, which has been classified as dry, had encountered around 50-60m multiple sandstone layers in the two formations. Few sandstone layers in Sleipner formation were found to have traces of petroleum.
Aker BP has permanently plugged and abandoned the 25/2-19 S and 25/2-19 A wells following the completion of their drilling.
