WebJan 21, 2024 · A two-dimensional (2-D) seismic section is a cross section of a 3-D seismic response. Despite the fact that a 2-D section contains signal from all directions, including out-of-plane of the profile, 2-D migration normally assumes that all of the signal comes from the plane of the profile itself. Web2. Migration On Seismic Data . Seismic data migration is a seismic data processing that has the aims to map a seismic event in its actual position [5]. Seismic data migration as part of the seismic data processing attempts to eliminate the diffraction and reflector tilt effects. There are many migration methods that are used to produce
