Our main focus has been the Central Graben Salt diapirs, where we have examined the detailed geometry of the reservoirs and salt diapirs at all scales from seismic to cores over some 12 oil fields. Debris flows in the Chalk, which have slumped off diapir crests, have become a recent new play in the central Graben with good examples described on the Kyle Field (Davison et al. 2000a and 2000b ).

The Central Graben diapirs created topography of at least several tens of metres during the Palaeocene and this created enough relief to divert turbidite flows around the domes. Prediction of sedimentation patterns around salt domes is important to understanding reservoir distribution.
