LONDON -- Hansa Hydrocarbons has acquired Serica Energy UK’s entire working interests and operatorship in blocks 48/16b and 48/16a in the North Sea. The company now holds a 100% working interest in both licenses.
Hansa farmed into block 48/16b last year for a 35% working interest and participated in the drilling of the 48/16b-3z appraisal well earlier this year. The well was designed to appraise the Thoresby gas field (formerly known as Chablis), which was discovered in 2002 with well 48/16b-2. The well encountered a gas-bearing interval with better quality reservoir and hydrocarbon saturation than the discovery well, the company says. The two wells also share a common gas-water contact, confirming continuity of the reservoir.
The Thoresby field is a large low-relief structure in the Leman sandstone, the major gas-bearing reservoir across the European Permian basin. Hansa is now conducting a high-resolution 2D seismic survey and a 3D seismic reprocessing project to provide an accurate depth image of the Leman sandstone reservoir. Field development planning is scheduled for 2010.
