  • Patent number: 7389205
    Abstract: An oilfield equipment identifying apparatus comprising a computer loaded with an oilfield equipment database. A unique identification code is input into the computer for each piece of oilfield equipment in the drill string to form a reference in the oilfield equipment database to each piece of oilfield equipment in the drill string. A drilling monitoring device receives input signals indicative of at least one of rotating and non-rotating usage of the drill string and output signals to the computer wherein the computer continuously and automatically monitors the cumulative rotating usage and non-rotating usage of each piece of oilfield equipment identified in the drill string.

  • Patent number: 6480811
    Abstract: An oilfield equipment identifying apparatus for tracking selected parameters for each of a plurality of pieces of oilfield equipment adapted to be inserted into a drill string supported by a drilling rig. The drilling rig also supports a drilling device for selectively rotating portions of the drill string to form a well bore. The apparatus comprises a computer loaded with an oilfield equipment database. A reader is provided for inputting into the computer a unique identification code for each piece of oilfield equipment added to the drill string so as to build a grid including a reference to each piece of oilfield equipment.
