Block 15/21g – Central North Sea
Serica 30%, Encore 40% (operator), Nautical Petroleum 30%
Block 15/21g was awarded to Serica in the 25th Round of UK Offshore Licensing in 2008. It occupies an area of 33 square kilometres in the Central North Sea, immediately west of the Scott field, and contains a potentially significant extension to the existing Jurassic oil discovery in well 15/21-38.
The "Spaniards" Lead is a prospective stratigraphic trap down-dip from discovery well 15/21-38, which flowed 2660 bpd of 25° API oil from a good quality Jurassic aged Upper Claymore sand. Pressure interpretation suggests that the oil column may extend down-dip into Block 15/21g. The Company plans to carry out reprocessing of available 3D seismic data in order to better define the trap before committing to drill a well.
