The data records include data about a drill string in a well. Each data record includes a depth zone, wherein the depth zone includes range a of depths in the well, description a of component in a the drill string in the depth zone for this data record, and failure flag a that, when set, represents failure in a the drill string at the depth zone for this data record. A pro - cessor with access to the memory generates and transmits for display on graphical a user interface a schematic of a portion of the drill string. The processor emphasizes on the schematic of the portion of the drill string on the graphical user interface a representation of an emphasized depth zone, wherein a failure flag in data record a for the emphasized depth zone is set.
