Description
2D CO-MF search engine
This procedure execute the calculation of 2D common offset MultiFocusing (CO MF). The calculation can be performed standalone using CPU /GPU or remotely on cluster using CPU/GPU nodes.
The input to regularization procedure must be binned data, thus additional binning after data regularization must not be applied as it may create a problem with data enhancement procedure.
Input data – seismic data and parametrization tables
Output data – Database file with calculated optimal MF parameters and corresponding to them time-corrected events.
Input data
Storage file
GMFPickingItem
Link to velocity constrain picking that can be taken from another procedure
SEG-Y data handle
Link to input seismic data
Input sorted headers (of seismic data)
Trace headers of input data
Trace headers - virtual geometry
Virtual geometry for CO MF where each CDP divided into offset classes, produced by Virtual geometry COMF 2D
MF Tables Parametrization
Service object provides parameters for MF search
V0 Map
Parameters
File with picking
File consists the velocity corridor. The search of the optimal MF parameters will be performed only inside this constrain. If not specified the search will be performed for all velocities
CO Aperture
The parameter that is responsible for selection of data for calculation. Usually it is bigger than the half offset class separation
Default: 250
CO aperture mode
Compression
