Automatic Editing of Travel Time and Density Logs


J. G. Patchett, Amoco Production Research


A statistical editing technique can be used to great advantage when constructing syn- thetic seismograms. Editing of travel time and density log data permits construction of valid synthetic seismograms in the event a significant amount of these logging measure- ments are incorrect due to hole conditions. In addition to editing, this technique: 1. Estimates travel time and/or density over sections of the wellbore where these measurements were not recorded.
