The Norwegian Petroleum Directorate has announced that Lundin Norway is set to complete drilling of appraisal wells 16/2-13 S and 16/2-13 A in the North Sea.
Lundin Norway is operator of production licence 501where the Johan Sverdrup field is located.
Wells 16/2-13 S and 16/2-13 A were drilled by the Transocean Arctic drilling facility to vertical depths of 2,060m and 2,172m respectively, and total measured depths of 2,065m and 2,751m below the sea surface. In 2010, an oil discovery 16/2-6 Johan Sverdrup was proven in Upper Jurassic reservoir rocks.
Both wells were drilled about 2.5km north-east of the discovery well 16/2-6, and 6.5km south-east of appraisal well 16/2-10 located in production licence 265. The company said the objective of drilling 16/2-13 S was to investigate reservoir properties, the thickness and depth of the reservoir.
It also wanted to check the oil / water contact in the northeastern part of the discovery, where oil / water contact was not encountered.
A gross oil column of about 25m in Upper to Middle Jurassic rocks, of which 15m in reservoir rocks is said to be with very good reservoir quality. Appraisal well 16/2-13 A encountered the reservoir with an oil column of 12m, about 1,250m north of well 16/2-13 S.
The company intended to prove oil / water contact which was three metres deeper than in the neighbouring wells in the Johan Sverdrup discovery in production licence 501.
Lundin Norway said reservoir came in three metres shallower than expected, and is positive for the north-east flank of the Johan Sverdrup discovery. The well was indicated a good reservoir size, thickness and moderate to very good reservoir properties to the north.
Extensive data acquisition and sampling has been carried out at the well, which are the ninth and tenth exploration wells in production licence 501. Wells will be permanently plugged and abandoned. Permian or older rocks were terminated.
