A plurality of data records is stored in a memory. The data records include data about a drill string in a well. Each data record includes a depth zone, wherein the depth zone includes a range of depths in the well, a description of a component in the drill string in the depth zone for this data record, and a failure flag that, when set, represents a failure in the drill string at the depth zone for this data record. A processor with access to the memory generates and transmits for display on a graphical 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 a data record for the emphasized depth zone is set.
