Wheeler diagrams are mainly constructed within the context of sequence stratigraphy with the diagrams initially proposed by Harry E. Wheeler to help establish a depositional framework of a time stratigraphic unit. Seismic data has shown another perspective of interpreting such diagrams by allowing large regions of a depositional setting to be observed in 3D within a defined spatiotemporal framework. Nevertheless, seismic data mostly contains limited vertical resolution and requires integration with well data. This paper reviews the advantages and pitfalls of seismically driven interpretations and argues that 4D Wheeler diagrams, with the introduction of a fourth dimension of stratigraphic thickness, are likely to become an important future trend in subsurface sequence stratigraphic interpretation.
