摘要： A system and method in accordance with the invention communicator remotely with remotely controllable down hole tools in a well bore at a drilling installation. At the surface, high energy pressure impulses directed into the tubing or the annulus, or both, being at a level to propagate through an interface between very different impedances zones, such as an upper level gas zone and a lower level of mobile fluid media extending down into the desired downhole location. The pressure impulses, provided by directionally gating along the longitudinal confining path a pressure impulse initially having sharp leading and trailing edges, reach the downhole location as physical perturbations forming a discernible pattern that can be detected by one or more energy responsive transducers. With combinations of these signals, one of a number of separate control devices can be remotely actuated. The system avoids the need for physical or electrical connections and concurrently greatly reduces the likelihood of accidental operation

摘要： The present invention relates to a method and apparatus for anchoring an expandable tubular within a wellbore prior to expanding the length of the expandable tubular into contact with the wellbore. An expandable system comprises the expandable tubular and a deployment tool, wherein the deployment tool exerts radial force against the expandable tubular to expand at least a portion of the expandable tubular into contact with the wellbore to anchor the expandable tubular prior to the expansion process. A method for anchoring an expandable tubular within a wellbore prior to the expansion process is also provided, wherein radial force expands the expandable tubular into contact with the wellbore to initially anchor the expandable tubular. A method for altering the shape of the anchor is also provided.

摘要： A monobore wellbore (68) and method for completing the same are disclosed. The monobore wellbore (68) comprises a first casing (74) having an inner diameter (76) and a lap region (80). A second casing (90) is positioned within the wellbore (70) by passing through the first casing (74) such that an uphole end of the second casing (90) is positioned within the lap region (80) of the first casing (74). After downhole expansion, the second casing (90) has an inner diameter (114) that is substantially the same as the inner diameter (76) of the first casing. The uphole end of the second wellbore is coupled to the lap region (80) of the first casing (74) to create a mechanical connection and a hydraulic seal, thereby creating the monobore wellbore (68).

摘要： A through tubing casing plug is disclosed. It features a stack of nested cup shaped elements that initially slope to reduce the run in diameter. The stack is compressed to force the periphery of the nested cups to move outwardly so that the collective outer surfaces of the cups can seal on the casing. The cups have sufficient initial thickness so that they remain intact despite some radial growth resulting from the compression process. In a particular example, the run in dimension is 2.13 inches and the stack expands to seal against casing with an inside diameter of 6.9 inches while holding a differential of 500 pounds per square inch and more.

摘要： The present invention provides a hanger for either casing or tubing strings that electrically insulates the internal suspension system of the hanger from the hanger's external seal. Electrical power is typically transferred through a hanger via the internal suspension system. If electrical umbilicals are used, connecting devices may be located within the internal suspension system for connecting an upper and lower umbilical and transferring power through the hanger. If a rigid tubular conductor is used, the suspension system may be ported to allow the passage of electrical feedthroughs or, in the case of tubing hangers, the tubing itself maybe charged with electrical power. By insulating the suspension system from the external seal, potential electrical hazards are eliminated.

摘要： A method of increasing the collapse resistance of a tubular comprises locating a tool having at least one, and typically three, bearing members within a tubular. The bearing members are positioned in engagement with a wall of the tubular to apply a radial force to a discrete zone of the wall. This radial force is then applied to further discrete zones of the wall, the level of radial force being selected such that the collapse resistance of the tubular is increased.

摘要： A control system for a hydrocarbon well is also disclosed. A control valve system is used to control the flow of fluid being produced by the well. A real time sensor is provided downhole and is used to make real time measurements of phase characteristics of the fluid. A controller is used to control the valve system so as to reduce the risk of undesirable phase transitions in the fluid based on the real time measurements made by the sensor. The sensor includes an acoustic transducer configured to emit acoustic energy into the fluid at a level which causes a phase transition in the fluid. The controller determines the level of acoustic energy emitted into the fluid, and also determines the pressure associated with a phase transition using the level of emitted acoustic energy.
