Editor or select the log, hold down the CTRL key and click on the item you want to
remove.
Four different categories of items exist – drill, solid, hollow and fluid items. Each of
them requires different fields to be filled in the data format.
Drill Item:
Drill items are the items, which make up the borehole itself. A bottom depth and a
diameter characterize them. The drill item top depth is automatically set to the
bottom depth of the drill item above it (on top of it) or, if there is none, it will be set
to the surface depth. This ensures that at any given depth, only one drill item exists,
and that the borehole is continuous (no non-drilled depth zones between two drilled
zones). At least one drill item must exist in any engineering log.
Select the Borehole Drill item from the items list and set the depth as well as the
external diameter data using the Tabular Editor.
