Lundin Finds More Oil at Johan Sverdrup

15 Jul 2013

Sweden's Lundin Petroleum reported Friday that it has completed appraisal well 16/3-6 on the Johan discovery in the Norwegian North Sea, finding a 37.5-foot oil column in good quality sandstone of Upper Jurassic age.

The well is located at the eastern flank of the Johan Sverdrup discovery. The well found a 78.5-foot gross reservoir section of which 37.5 feet were above the Oil Water Contact (OWC) – which was established at 6,320 feet below mean sea level.

Lundin said the reservoir sequence is entirely of late Jurassic age and consists of reservoir sandstone of excellent quality with a high net to gross ratio, and that the reservoir is resting directly on granitic basement.

The well was drilled to a total depth of 6,645 feet below sea level into granitic basement. A comprehensive coring and logging program has been successfully completed, including a log-inject log wireline run for EOR screening. A pressure gauge was installed in the hole to monitor the reservoir pressure for a period of between two and five years.
