Topic:
How to copy a portion of a 3D survey into another project.

Description:
Also, how to merge interpretation on the portioned seismic.
There are three ways to do this. 
1.) Create a new project using Project_Rename and null out the seismic 
    you do not want to see.
2.) Create a new project and share/copy seismic by cdp/line range.
3.) Segy export cdp/line.
range and and reload , export and import interp.

Solution:
Project_Rename method:

1.) Create new project with same projection/units and same number of DSL's as
    the original project.

2.) Do a UNIX copy of files from master to new project(s), and run
   "project_rename.csh" under "IESX Application Selection" menu. Make sure you
    copy Old project/DSL1 to New project/DLS1, etc...

3.) Run Project_rename from the Application Manager and follow intstructions.
    See "How to" procedure in "Project_Rename".

4.) In the new project, select DataManager > Seismic > Copy, and toggle
    "Option" button to 'null data' to wipe out the data you don't want to see.

5.) For deletion of interpretation from the nulled area, use DataManager > 
    Interpretation > Delete. Select horizons, faults, and survey(s), but do not
    select horizon or fault names under  "Select items for deletion".  Select
    "Change Area" and input cdp/inline range to delete.


To share/copy into new project:

1.) Create new project with same projections/units as original.

2.) DataManager > Seismic > Share, select original project, survey/class and 
    select 'Share'.

3.) DataManager > Seismic > Copy, select original survey/class and type in a
    new output class. Select 'Change Area' and input cdp/line range you want to 
    copy. Then unshare in DataManager > Seismic > Share.

4.) To merge interpretation over, use DataManager > Interpretation > Merge,
    select source "original" project, survey, horizons, faults, fault contacts,
    and traces, select destination survey, and select 'Change Area' to select
    line/cdp range to copy into to.


To segy export and reload:

1.) In original project, DataManager > Seismic > SEGY export, select
    survey/class, set Output parameters, select 'Change Area' to output
    cdp/line range to restrict and 'Generate'.

2.) In original project, DataManager > Interpretation > Export, select format,
    interpretation, survey, select 'Change Area' to restrict output and input
    filename, 'Export'.

3.) In new project, DataManager > Seismic > Load Seismic and reload using same
    survey coordinates as before. 

4.) In new project, DataManager > Interpretation > Import, select format, input
    filename, 'View' and 'Load'.
