  • Automatic drilling system
    Patent number: 7059427
    Abstract: An automatic drilling system is disclosed which includes an electric servo motor operatively coupled to a winch brake control, a servo controller operatively coupled to the servo motor, and a drum position encoder rotationally coupled to a winch drum. The controller is adapted to operate the servo motor in response to measurements of position made by the encoder so that a selected rate of rotation of the drum is maintained.

  • Automated method and system for determining the state of well operations and performing process evaluation
    Patent number: 6892812
    Abstract: An automated method and system for determining the state of a drilling or other suitable well operations includes storing a plurality of states for the well operation. Mechanical and hydraulic data is received for the well operation. Based on the mechanical and hydraulic data, one of the states is automatically selected as the state of the well operation. Process evaluation may be performed based on the state of the well operation.

  • Automated method and system for recognizing well control events
    Patent number: 6820702
    Abstract: An automated method and system for recognizing a well control event includes determining a state of drilling operations. When drilling operations are in a circulating state, a benchmark for a relative flow value. The relative flow value is based on a flow of drilling fluid into a well bore and a flow of drilling fluid out of the well bore. A limit on variation of the relative flow value is determined from the benchmark. A cumulative sum for the relative flow value is determined over time in response to the relative flow value exceeding the limit. A well control event is recognized based on the cumulative sum.
