The Waveney Field, Block 48/17c, UK Southern North Sea
The Waveney Field lies entirely within UK block 48/17c in the Southern Gas Basin, approximately 46 km north-east of the Norfolk coast line and to the west of the Mobil’s Lancelot and Guinevere Fields. The water depth is approximately 75 ft. The field was discovered in 1996 by the 48/17c-12 well and brought on production in 1998 following a 14 month fast track development program and the drilling of two 2500 ft horizontal wells. The gas field is a low relief northwest trending asymmetrical anticline, with a length of 6 kms, and a maximum width of 2 kms. The crest of the structure is at approximately 7748 ft. TVDSS. The original reserves were 84 bcf. The reservoir predominantly comprises aeolian dune sandstones of the Upper Permian Rotliegend with an average reservoir quality range of 7-10% porosity and 0.1-200mD permeability. The hydrocarbons are sourced from down dip Carboniferous Westphalian Coals.
