Above the Franklin field (Central Graben area, UK North Sea), the Forties Member sandstones of the Palaeocene Sele Formation are too thin to be resolved by seismic. We show that synthetic seismic modelling indicates that the seismic signal is affected by such thin Forties sandstones. In conjunction with good well control, we have used these effects to interpret the gross thickness of Forties sandstones within the Franklin overburden. Moreover, this method has revealed that local structural features may have played a role in the deposition of the Forties sands. An infill well is being drilled that will be used to test our prediction.
