2 - The SeisX Setup

In this chapter we are going to learn how to set up a project for the first time. SeisX is now able to automatically create a directory and populate the project with a series of setup files. To help with the organization, we will create additional directories and copy a well synthetic template.

Starting SeisX -- Creating a SeisX project from unix

As a first step with a new user, it is recommended that a previously build project be set up for them. The unix tar command should be used to copy the seisx files, tar preserves dates and links, much better than the cp with the recursive option. 

tar -cf - gregg  | (cd /dat/photon3/gm; tar -xBpf - )
tar -cf - pek  | (cd /dat/photon4/hm; tar -xBpf - )
I recommend using SeisX 3.5 for a new project (As of October 2003). Version 3.5 is very much faster for picking events and the bugs and work arounds are better known. Use version 3.6 when you want the following options: When you fire up SeisX for the first time, you need to set up some options to point to where common files exist. Do this carefully, if you make a mistake you will have to erase some hidden files and start over (.sptrc35 in the home directory and .proj.lst_v3.00 located in your user_support35 directory). Setup these options at EnCana: 
#system support
/apps/paradigm/PG00/PG99/seisx_support
#user support
/home17/p007042/user_support35
#help application
/apps/paradigm/PG99/bin/acroread

#PS hardcopy

#cgm files zeh's new way of doing this
/xlation/ekeyser
#hpgl

#text printer name

Here is the screen selection I like to use: 
Basemap screen2
Base map attributes screen1
Color Dialog default
Color legend default
Fault cube screen1
horizon default
synth default
value default
seismic display screen1
seismic attributes screen1
culture screen1
grid screen1
grid contour screen 1
To help organize SeisX stuff, I like to keep my segy 2D and 3D separate. I also create a directory called asc for my culture and well stuff! 
 mkdir asc
 mkdir 2d
 mkdir 3d
Remember to open up the permissions for others to place data here. 
chmod asc
I like changing the background to Grey65 and the wiggle trace background to light grey. Here are some useful templates I like. I have a sonic-gamma template that you may find useful. There is also two colour palettes, one for a blue brown seismic colour bar and the other is a spectrum with a very light cyan around the zero crossing. Note you can click on these files and save them to you project. Or if you are on the EnCana system you can copy them from my suer_support35. 
cp -R /home/ekeyser/user_support35/gek .

Starting SeisX -- Creating a SeisX project on an NT machine

On a Unix machine type the appropriate alias to start the program (sx34?). Click on the SeisX icon if you are on an NT machine. When the license manager comes up, select the SeisX Full Functionality and press ok

Press the Create... button to create a new Project. Fill out the Project Name SX200, Directory path and the project description. Press the Create New Project button. In a few seconds you have a directory structure created with a number of files copied over.

Here is what the index directory should look like. 

 Directory of D:\Projects\index

06/11/99  04:15p        DIR          .
06/11/99  04:15p        DIR          ..
06/11/99  04:15p        DIR          Aliases
06/11/99  04:15p        DIR          Horizons
06/11/99  04:15p                4,229 logs.default
06/11/99  04:15p        DIR          Mistie
06/11/99  04:15p        DIR          palettes
06/11/99  04:15p        DIR          Seismic
06/11/99  04:15p                    0 spt.ttl
06/11/99  04:15p        DIR          StratSym31
06/11/99  04:15p        DIR          SX200
06/11/99  04:15p        DIR          Synthetics
06/11/99  04:15p        DIR          TDCurves
06/11/99  04:15p        DIR          template
06/11/99  04:15p        DIR          Wells
06/11/99  04:15p                   158 __lock
              16 File(s)          4,387 bytes
                                        1,591,869,440 bytes free
Numerous directories are set up for the user. Notice the ___lock file. If SeisX blows up you may have to manually remove this file to get access to the project. Copy the file sonic-gamma.template from the index_data/wells directory to the template sub directory. This file sets up a nice looking synthetic display. I do not find the default.template useful!

Setting up Seismic Directories, ASC Directories, getting sonic-gamma.template

Make a directory under the project called asc. We will use this location to keep all of our culture. Create a second directory called segy. Copy all files from the index_data subdirectory /asc and /segy. This will provide the culture, SEGY seismic data and well control for the course. We need to organize ourselves a little bit or else we will soon find our project directory will rapidly fill up with numerous horizon pick files.

$ pwd

$ ls

$ cd ..
$ cd segy
$ cp D:/Projects/index_data/segy/* .
$ ls

103.segy           106.segy           300-3D.MIG.0.indx
Go to the seismic directory and create a sub directory called process. We will use this directory to place our processed files. 
$ pwd
D:/Projects/index
$ ls
Aliases       SX200         Synthetics    __lock        spt.ttl
Horizons      Seismic       TDCurves      logs.default  template

$ cd seismic
$ ls
WorkingSet.PDB            intersect.PDB             intersect_name.PDX
WorkingSet.PDD            intersect.PDD
WorkingSet_LINE_NAME.PDX  intersect.PDX
$ mkdir process
$ ls
WorkingSet.PDB            intersect.PDB             intersect_name.PDX
WorkingSet.PDD            intersect.PDD             process
WorkingSet_LINE_NAME.PDX  intersect.PDX
$
Go to the template directory and copy all templates. The sonic-gamma template presents an hourglass type log display with the gamma curve on the left and the sonic on the right. 
$ pwd
D:/Projects/index
$ cd template
$ cp D:/Projects/index_data/template/* .
$ ls
default.template      sonic-gamma.template
Now copy the files from the index_data/wells directory. The files contain our general well information, tops and deviation survey. Two awk's are provided to convert the excel spread sheets containing our data into SeisX Photon Ascii format. 
$ cd Wells
$ ls
Logs          well.db       wellpost.PDD
WELL_ID.PDX   wellpost.PDB  xsecfmn.dat
$ cp D:/Projects/index_data/wells/* .
$ ls
DEVA2SX.AK     Well-E.las     Welltops.csv   well.db        welltops.xls
Logs           Well-F.las     deviation.asc  wellpost.PDB   wlsa2sx.ak
WELL_ID.PDX    Well-I.las     deviation.csv  wellpost.PDD   xsecfmn.dat
Well-B.las     Well-R.las     deviation.xls  welltops.asc

An Introduction to the SeisX Interface: Brief description of some of the Pull Down Menus

SeisX's menu system has the major options across the top. Seismic data are loaded under the Project. Wells are loaded under Well. Culture is loaded from the base map using the culture icon. A blank base map can be built with Project, Create base Map. generally is used from left to right. Wells are loaded from the Well option.
