Three versions of the WellSight Log Viewer programs are currently available to view or print your logfiles.  Version 4.4d is used for vertical and horizontal mudlogs with the file extensions: .log and .hzl, and Version 5.3c is used for vertical and horizontal mudlogs with the file extensions: .mlg and .hlg files.  Version 6.2 + is now fully backward compatible and will open, view and print Version 4, 5 and 6 logs.  Versions 4.4d and 5.3c of the Viewer are provided because they retain the function of exporting data in addition to viewing and printing, not included in the newer Version 6.2.  If you don't have a log viewer, click on one of the images below to download a copy.
