Description
Import static shifts from text files
This procedure designed to import statics corrections (source, receiver, common midpoint) from ASCII file into GNavigator software. Statics correction of ASCII file contains tree columns: X-Y coordinates and statics correction value. Coordinates should be in accordance with the attribute of statics implementation\correction - source, receiver, common midpoint. Connected model that uses the output of statics corrections of this module is «Apply Static Shifts», which use statistic correction to traces.
Input data – ASCII files with statics correction
Output data – imported statics correction
Input data
Trace headers
Link to geometry tables - trace headers that loaded into processing system (for example from «Load SGY»).
This parameter allows to check between the information in ASCII file and geometry tables.
Parameters
Sources file name
Path and file name of ASCII file with source statics correction
Receivers file name
Path and file name of ASCII file with receiver statics correction
CMP file name
And file name of ASCII file with CMP statics correction
Use interpolation
By default FALSE. If checked, the user should provide the interpolation parameters.
Step X
Provide interpolation step in X direction
Step Y
Provide interpolation step in Y direction
Minimum distance
Minimum distance (meters), at the point where, for example, receiver from ASCII file will comply with receiver from geometry table talking into account some inaccuracy in coordinates
Time format
Select the statics shift file time format from the drop down menu. Seconds or milliseconds
Coordinates type
Choose from the available options from the drop down menu.
Coordinates unit
Choose the coordinate unit from the drop down menu.
Subtract elevation statics
By default FALSE. If checked, it will subtract the elevation statics from the input trace headers.
Datum
Specify the datum value
V replacement
Provide the replacement velocity value.
