  • Construction casing and production zone
  • Hydrostratigraphic samples
  • Lithological samples
  • Stratigraphic samples
  • Water chemistry samples
  • Water cut (construction).
Description of the logging interval, including lithologies in addition to the Major and Minor Lithological Codes.
Lith Code
Code identifying the lithology of the logging interval. See Lithological Codes on the Code Definitions page.
Log Date
Date when the well was logged.
Logger Name
Name of the person (driller) who logged the drillhole.
Name of the well, if available.

Code identifying one or more observation networks to which the well is associated, if applicable.​

Obswell No.

Unique code identifying the water well as ​an observation well, i.e. monitored for water levels. An observation well is associated with the relevant Obswell Network.

Not all water wells are observation wells.
