Description
3D CO-MF search engine
This procedure execute the calculation of 3D 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
SEG-Y data handle
Input trace headers (of seismic data)
Input bin grid
Trace headers for MF
MF Tables Parametrization
Link to Fresnel Zone factor table, used for calculation of data consists of few acquisitions with different parameters (nominal fold coverage). Calculation with this table will perform unique MF nominal fold by using spatially varying Fresnel Zone percentage
GMFPickingItem
Link to velocity constrain picking that can be taken from another procedure

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
