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
