The sinusoid represents the magnitude of the travel time variation between the fast and slow orientation 'above' the reflection event. Surface consistent residual statics (a second round)Īzimuthally sorted gathers have sinusoidal perturbations about an average RMS velocity. Refraction statics applied to a floating datum Not all of them are necessary.įilter (minimum phase equivalent of sweep)
List of operations, more or less the order in which they could be applied. Testing A simple example marine processing flow A simple example of a land processing flow Parameter choices are almost always subjective, but a good rule of thumb is to keep things as simple as possible unless there is a reason suggesting otherwise. Some parameters will be defined, for instance, by the acquisition geometry and some must be determined for the particular data being process by the process of testing. Several of the stages are strongly interdependent and each of the processing routines will require several parameters to be chosen or defaulted. Most processing routines accept input data, apply a process to it and produce output which is saved before passing it to the next processing stage.
The following is a not-exhaustive list of geophysical contractors who specialize in seismic data processingĪ processing flow is a collection of processing routines strung together and applied to a data volume. Most commercial seismic data processing is carried out by contractors who are able to perform most jobs quickly and cheaply with specialized staff, software, and hardware.
