Seismic interpreters must have a reliable methodology that allows them to (1) correlate seismic reflection events with well-log-defined sequence boundaries and (2) specify which seismic facies windows correspond to the rock facies intervals defined by well control.

The basic geometry of an onshore three-dimensional (3-D) seismic recording grid is based on five parameters: source-station spacing, receiver-station spacing, source-line spacing. receiver-line spacing, and recording swath size.
