ZIP file contains the orignal DST data supplied to the KGS by Trilobite Testing LLC . Four files are in each archive. The .flg file is an ascii file that has time and pressure at change points (open, shutin, etc.). The .csv is the original data extracted into a comma delimited file. The last two files (the .inf file and a file with a variable extension) are binary files that require Alpine DST software for display.
