"Events" store depth-related information and annotations about directional wells.   This can include casing information, gas kicks or fluid losses, drilling or rig events, lithological data from cuttings, or sidetrack annotation.

Events are stored in Petra’s Main Module in the Interval tab in the DirWellEvents table.  Here, the well events can be edited or deleted.

There are three different kinds of events:  Text boxes, point events, and range events.  Text boxes just contain an entry for text.  Point events save information about a single depth on a directional well.  Range events save data about a part of the directional well between a top and base.
