Abstract:
The subsurface geologist must use facies models and sequence stratigraphic concepts to correlate well data. I show several examples of deltaic reservoirs, originally depicted as consisting of horizontal layers (i.e. the layer-cake). The outcrop examples suggest that sandstones within the delta front dip seaward. This fundamentally challenges reservoir models that invoke flat versus dipping beds and I demonstrate how this can be applied to correlation of core and well log data sets. The regional-scale stratigraphic results also suggest very different exploration models in the search for basin-distal reservoir sandstones.
A key problem remains the correlation of deltaic sandstones along depositional strike, for which we have far less outcrop data and do not yet understand the main controlling
