IMPORTING SEG-Y SUB-BOTTOM PROFILER DATA WITH VARIABLE DELAY

TIME (from SBP 300)

From the main screen of Kingdom, select Surveys > Import SEG-Y

On pop-up screen, select Import Multiple 2D SEG Y Files with Coordinates. Click Next.

Bulk Import window will pop-up, click on Browse button. Pop-up window will appear. Select the

correct path to the folder containing the SEG-Y files. If the extension of the SEG-Y files is not *.sgy,

then select All files (*.*).

Select files from the pop-up window, use Ctrl + left mouse click to select several files as necessary.

After selecting all files you wish to load, click on Open.

From the Specify Amplitude Format window, select 32-Bit IEEE Floating Point (format for the SEG-Y

files from SBP 300) and then click OK button. (I have tried using 8-Bit integer option, but the loading

hangs at the last trace, using 32-Bit IEEE Floating Point option does not)

The Select Seismic Data Volume Name window will pop-up.

Select *Amplitudes for Data Type then click Next > button. The SEG Y File Parameters window will

pop-up.

Do the following on this window:

1. Select on Use disk file name as the line name

2. Change Shotpoint Starts in Byte: to byte 5 (default is byte 17)

3. Change X-Coordinate Scale Factor to .01

4. Change Y-Coordinate Scale Factor to .01

Click Next > button to pop-up the Set Time Data Bounds window:

Do the following on this window:

1. Change Start Time Byte Location in Trace Header to 109 (default is 105)

2. Enter appropriate Start Time and End Time values under Output column (Start time should

be equivalent to the minimum recorded time for the “shallowest” section of the SEG-Y file

and End time should be equivalent to the maximum recorded time for the “deepest” section

of the SEG-Y file.

3. Click the Advance Loading Options … button for the Advance Options Override Input File

window to pop-up.

Do the following on this window:

1. Select Support Variable Start Times

2. Ensure that the value for Start Time (Milliseconds) Starts in Byte: is equivalent to the byte

value entered in the previous window, which is byte 109 in this case.

3. Click OK button to return to the previous window.

4. Double check / re-enter the Start and End time of Imported Trace in the appropriate column.

5. Click Next > button to continue on to the Save Data window

Select appropriate Output File Type, Output Data Format and Output Directory location, and then

click Finish button.

The data should then be loaded in to the project, and can be used (see example below for line

ML_17_EN which has several steps.
