Weald and Wessex Basin Fields

January 01, 2003


The Weald Basin of SE England is a lozenge shaped accumulation of sediments occuring from Southampton and Winchester in the west to Maidstone and Hastings in the east. It is approximately 150 km long by 60 km wide, covering an area of some 9000 km2 (Fig. 1). Several commercial oil and gas discoveries have been made, mostly on the flanks of the basin. These fields have been in continous production since the early 1980s. Field size in terms of recoverable hydrocarbons is small, 0.5 to 6MMBBL of oil is typical. Hydrocarbons are produced primarily from the Middle Jurassic Bathonian Great Oolite at Humbly Grove, Herriard, Storrington, Singleton, Stockbridge, Goodworth and Horndean fields but also from the Late Oxfordian-Early Kimmeridgian Corallian Sandstone at Palmers Wood; Portland Sandstone at Brockham and Godley Bridge; Corallian Limestone at Bletchingley; Purbeck Sandstones in Albury and Late Triassic Rhaetic calcarenites in Humbly Grove. Cumulative oil production from the basin as a whole is currently 19.1 MMSTB.
