Topic:
How to bulk shift a few 2D seismic lines in a survey.

Description:
User only needs to bulk shift a few seismic lines in a 2D survey.  Doesn't want
to bulk shift the whole survey of 2D lines.
        

Solution:
1)  Check to make sure you have sufficient amount of disk space for the new
    seismic data in Session Manager > Project > Update. If you need more disk
    space, please refer to:

Product: IESX
Version: 10.2
Application: DataManager
SearchType: HowTo
Synopsis: How to add disk space when DSL's are full.

Suggestion: Create the new data in a master project instead of an interpretation
project, so if another user wants to use this data, it will reside in the same
project as the original seismic. Also, makes backing up projects more
manageable. 

2)  IESX Session manager > Application > Computation Manager - SeisAn

3)  Select Seismic Bulk Shift, displays "enter shift in msec". 
    Input positive number to shift down in time and negative number to shift
    up in time. Select OK.

4)  At the "ComputationManager" window. Click on "Survey" at the top. Select
    the survey that the 2D lines, then select the 2D lines, under 'Input class'
    select the class the data is in.  Under "Attribute volume", enter a new
    class name and description(optional). Select OK and it inputs class name in
    the "Output class" list, select OK again and you are back at the
    "ComputationManager" window.  

5)  You should see under "Selected operations", "Seismic Bulk Shift" and nothing
    else.  If you see other processes, delete them.  If you don't delete them,
    when you press the start button, computation manager will do all processes
    in that list. Select "Start" to begin process.
 
NOTE: Remember, you always have the original class of data if you need to go
back to it.  If everything looks fine, you might want to delete the original
class of data to save disk space.
