This module is used to save both the internal & external dataset(s) in SEG-Y format.
Module name Save SEG-Y
Save SEG-Y module can be used to save both internal & external dataset(s) in SEG-Y format. In the below example, we are going to show the two scenarios of saving the data in SEG-Y format.
Scenario 1:
User reads the external dataset in SEG-Y format and did some operation (it can be anything like modifying the trace/text/binary header or applied a bandpass filter etc) and wants to output in SEG-Y format.
To read any external (SEG-Y) format, we must use "Read SEG-Y traces" module. In this example, we are applying a band pass filter to the input dataset and save the output dataset.
Inside Read SEG-Y module parameters we must change the option of "Load data to RAM" from No to YES. This is mandatory since the Save SEG-Y accepts the input data as "Input gather".
Parameters
Seismic file name Define the path and give an output file name with an extension of .sgy or .segy.
Save text header to separate file This will save the text/EBCDIC header as a separate file
Convert to feet It converts from Metric to Imperial measurement system
Saving mode Select append/direct. By default "append"
Rewrite file By default unchecked.
SEG-Y format This is the place where the user should select the available Data sample formats i.e Int4/Float4/IBM/IEEE etc
Trace header formats By default Geomage format. If user wants to save it a customized format then refer to "Read SEG-Y traces" module.
Raw It has many options to either to use or not to use raw headers.
Scalars These are scalars for coordinates, elevation and SP. By default -100 i.e. 100 cm or 10-2
Text header file The user can to import the text/EBCDIC file so that this file can be incorporated into text headers
Scenario 2:
Saving an internal file into external file using "Save SEG-Y" module.
In this example, we are going to apply some post stack processing on a stack and save the output.
FX-Decon filter output will be referenced/connected to Save SEG-Y as Input gather. In the parameters, give the Seismic file name and define other parameters as explained above.
