Hole Diameter computed from HALS borehole identification inversion (CDH) |
This is a log of measurements along a well bore (a well-log). You might have encountered this acronym CDH in your log evaluation software or any (ASCII) log files provided by the logging company. The code stands for 'Hole Diameter computed from HALS borehole identification inversion'. Usage of this log is not high and encountering it is a rare occasion. The values of this log represent the borehole diameter as measured by a logging device: a record of the borehole or the internal diameter of tubular goods. At a more general level these values are measures of the inside diameter (Inside diameter of an entity, such as an item of drillstring equipment).This log usually has the unit 'Cylinder Diameter'. Data from this log can be used to investigate the caliper diameter of the borehole. Similar logs are listed below:
