Oil and gas has been found in clastic reservoirs of Eocene, Palaeocene, Cretaceous and Jurassic age and in fractured basement of Devonian/Carboniferous age in the West of Shetland area, but the density of drilling is sparse and significant exploration success has been limited, a notable exception being the Laggan field discovery.  Analysis of West of Shetland drilling results has been discussed in various papers by Loizou (2008), who attributes these failures to be the result of poorly understood amplitude anomalies due to lithology, AVO artifacts and spurious DHIs rather than hydrocarbons.  The construction of a WoS regional database and the integration of data from numerous geoscience disciplines has enabled a seismic interpretation and modelling framework to be built, that can be used both in the identification & de-risking of prospects as well as for reservoir characterisation purposes.
