  • Patent number: 7026950
    Abstract: The present invention provides a method and apparatus for generating one or more than one physically detectable physical influence changes to control or manipulate a down hole device. The present invention intercepts existing control signals to various controllers on the rig and superimposes an encoded command on these existing control signals. The controllers comprise of motor drives, choke controllers, acoustic pulse generators, tracer injectors and other controllers that are used to generate a physically detectable changes in the rig environment. The encoded command acting on existing or new controllers generates a perceptible change in a physical parameter such as a variation in drilling mud pressure, a variation in drill string rotation speed, a variation is weight on bit, generation of acoustic pulse, or a variation in tracer injection properties.

  • Patent number: 6944547
    Abstract: A system and method for controlling operation of a drilling rig having a control management system, comprises programming the control system with at least one resource module, the at least one resource module having at least one operating model having at least one set of programmed operating rules related to at least one set of operating parameters. In addition, the system and method provide an authenticating hierarchical access to at least one user to the at least one resource module.
