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.

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.

Abstract: The present invention provides a method and apparatus for remotely analyzing and affirmatively notifying appropriate personnel of problems and events associated with an oil recovery system—comprising hundreds of oil rigs over a vast geographic area. The results of selected Health Checks, which are run on each oilrig, are reported to a central server. The central server populates a data base for the oil recovery system, displays a red/yellow/green color coded electronic notification and status for an entire oil recovery system and affirmatively alerts appropriate personnel of actions required to address events associated with an oilrig in an oil recovery system. The diagnostics run at each oilrig are configurable at the individual rig. The present invention provides a dynamic oilrig status reporting protocol that enables population and display of a tree node structure representing an entire oil recovery system status on a single screen at a top level.

Abstract: The system and method for use with a drawworks having a rotatable drum on which a line is wound, wherein the drawworks and the line are used for facilitating movement of a load suspended on the line, includes a drawworks control system for monitoring and controlling the drawworks. A brake arrangement is connected to the rotatable drum for limiting the rotation of the rotatable drum and at least one electrical motor is connected to the rotatable drum for driving the rotatable drum. A load signal representative of the load on the line is produced and a calculated torque value based on the load signal and electrical motor capacity is provided. The drawworks control system provides a signal representative of the calculated torque value to the electrical motor wherein pre-torquing is generated in the electrical motor in response to the signal.
