Structural dip

Structural dip is the mean orientation of a group of bedding features that are assumed to have been originally deposited almost horizontally, and reflects the bulk post depositional rotation due to tectonism.  A well can be zoned into a series of packets each with a different structural dip.  Boundaries between these zones can include faults, fracture zones and unconformities.  Removal of structural dip by rotation to the horizontal is required prior to any analysis of sediment dispersal from cross-bedding directions within a well section.
