Drillinginfo currently collects information about certain events related to drilling wells. The system keeps track of when these events occur as well as some detailed information about the event. (Well Event data is only available in Texas at this time.)
In Texas, the events are
Spud
Set Surface Casing
Set Production or Intermediate casing
Set Production String
Advanced notice of Intent to Plug
Prod Test
Blowout
Fire
Note: Searching for plugging under WellEvent is different than searching directly for plugging under the search wizard (see Plugging Wizard). A Well-Event plugging record is really an Advanced notice of Intent to Plug as opposed to the record of a plugging as recorded by some regulatory agency.
