scripts default iconSeisLab (Scripts) Publisher's description

A set of 140 functions (plus support functions called by them) for analysis and display of exploration-seismic data and well logs.

A set of 140 functions (plus support functions called by them) for analysis and display of exploration-seismic data and well logs. These functions read and write seismic data in standard SEG-Y format, read and write well logs in LAS-format 2.0, and perform many of the manipulations usually performed on these data types. They use standardized structures to represent seismic data and well data and thus allow simple concatenation of function calls.

The functions come with a manual in PDF format and scripts with examples. Several versions of Matlab were released during their development. Presently, I run them under R2006b but I try to keep them compatible with R12 and use version-specific code to handle incompatibilities between this and previous Matlab versions that I happen to find. However, this is probably the last release to do so. The next release, SeisLab 3, will use Matlab features introduced in R13 and R14.

Generally, I make an effort to avoid functions from toolboxes; however, I am aware of at least one call to a function in the Optimization Toolbox.

In case you already have SeisLab installed you can find its distribution ID by typing "ddid" at the Matlab prompt. If you get the error message "Undefined function or variable 'ddid'." then you have the very first release of SeisLab. Otherwise, compare the distribution ID with that of this release. If it is lower then this release is newer.

Also, please note that a new version, SeisLab 3.0, is now available from the Matlab File Exchange. That new version does no longer support Matlab prior to R14, and some functions require R2007a.

EXAMPLE (used to plot the attached figure):

% Read interactively selected SEG-Y file
seismic = read_segy_file;

% Make a color plot of the data read

% Make a wiggle plot on top of the color plot
% and specify a title
s_wplot(seismic,{'figure','old'}, ...
{'title','Wiggle over color'})

System Requirements:

MATLAB 6.5.1 (R13SP1)
Program Release Status: New Release
Program Install Support: Install and Uninstall
