Rock Physics Driven Reservoir and Fluid Characterisation in the SNS – From Carboniferous to Bunter

摘要

The Southern Gas Basin of the UK North Sea has been an active theatre of exploration and production for over 40 years. During this time hundreds of wells have been drilled and three major prospective gas play systems Bunter, Rotliegendes and Carboniferous, identified. The major recent geophysical tool has been 3D pre stack anisotropic depth migration which has been successful in revealing depth structure traps beneath the distorting lens of the Chalk and Zechstein salts.
