This lecture explains the NMO (Normal Moveout), DMO (Dip Moveout) and LMO (Linear Moveout) in seismic data processing. Also discussed more in detail about the a shot gather data and the events recorded in a shot record with respect to the position of events. A shot record showing source, receivers, rays, reflection points, and midpoints. The increase of travel time with offset (source-receiver distance) is the normal moveout effect.
