Before drilling the 24/9-15 A appraisal well, Aker BP estimated for Frosk, recoverable resources between 31 – 63 MMboe.
The objective of 24/9-15 S wildcat well was to prove petroleum and asses reservoir potential in the Intra Hordaland Gp injectites. An oil column of 49 m was encountered within sandy layers totalling about 10 m, mainly with very good reservoir properties. The oil/water contact was encountered 1836 m below the sea surface.
The preliminary size of the discovery is between 2 – 10 MMboe, and it extends into the neighbouring licence, PL869. The licensees will continue to assess the discovery together with other nearby discoveries, regarding follow-up and potential development.
24/9-15 A appraisal well was targeting to delimit the northern part of the Frosk (24/9-12 S) oil discovery. The well encountered oil-bearing injectite zones totalling 50 m with very good to extremely good reservoir properties in the Hordaland Gp.
The wells, which are also pilot wells for test production, were drilled diagonally and horizontally, 2 and 3 km northeast and north respectively, from the subsea template on the Bøyla field in the central part of the North Sea.
The plan is to carry out test production from bilateral wells in the Frosk reservoir starting in the Q3 2019, with an initial duration of six months. The production will take place via the subsea template on the Bøyla field and will be transported 26 km north to the Alvheim production vessel (FPSO). The primary objective of the test production is to reduce the risk associated with recovering these resources.
