MD/TVD Conversion
New in version 5000.0.1.6 is a generic conversion utility that will convert an ASCII file of
well-related measured depth (MD) data to true vertical depth (TVD), also including subsea
true vertical depth (TVDSS) and X/Y absolute and relative coordinates for each point. The
reverse operation is also possible, i.e. from TVD to MD. The following have been added:
• fileMDtoTVD command line utility for file-based conversions
• fileTVDtoMD command line utility for file-based conversions
• TvdConvert GUI for file-based conversions.
Utilities fileMDtoTVD and fileTVDtoMD: file-based bulk conversion of MD to TVD
(and vice versa) within the context of a specified OW project. These utilities takes as input
an OpenWorks project name, a columnar ASCII file, and column number within the file for
UWI and MD or TVD columns. The corresponding depth is computed and additional
attributes are inserted at the beginning of each line of the specified output file. Any header
lines in the files will be ignored if prefixed with a
# symbol. Command-line usage:
prompt> fileMDtoTVD
Usage: fileMDtoTVD owproj filein fileout md_col uwi_col ?delim? ?units?
prompt> fileMDtoTVD
Usage: fileTVDtoMD owproj filein fileout tvd_col uwi_col ?delim? ?units?
<owproj> OpenWorks project name
<filein> input ASCII file name
<fileout> output ASCII file name
<tvd_col/md_col> column no. containing the depth measure to be converted
<uwi_col> column no. containing the well UWI
<delim> delimiter: Space, Tab or Comma
<units> depth units: 1 = meters, 2 = feet
Example:
prompt> fileMDtoTVD picks.dat picks2.dat 5 1 Tab 1
Utility TvdConvert: GUI for file-based multiple-point MD/TVD conversion. The user
choses an OpenWorks project, a conversion direction, and specifies the input and output
data files. The input is displayed in table form in the GUI and the separator (space, tab or
comma) is determined. Note that must be provided, there is no way to default this. After
specifying depth units, click ‘Run’ and then ‘View Output’:
To run the TvdConvert graphical user interface, first source the WebApps environment
then type the appropriate command:
prompt> source $OWHOME/WebApps/templates/wow.login
(if C-shell)
prompt> . $OWHOME/WebApps/templates/wow.profile (if Bourne shell)
prompt> TvdConvert
