  • Patent number: 10920530
    Abstract: A technique facilitates completion and stimulation of a reservoir, e.g. a lower tertiary reservoir. Initially a wellbore is drilled into the tertiary reservoir. Following drilling, the wellbore is completed by deploying completion equipment constructed to facilitate stimulation of the tertiary reservoir. The completion equipment may be operated in conjunction with a stimulation system to stimulate the tertiary reservoir and thus to enhance retrieval of hydrocarbon fluids contained within the tertiary reservoir.
    Type: Grant

  • Patent number: 8069913
    Abstract: A method of monitoring acoustic activity in a formation from a wellbore includes positioning a flow manipulation device into the wellbore, the flow manipulation device defining a flow path through which fluid may flow. Fluid is then pumped into the wellbore and through the manipulation device. A sensor disposed near the manipulation device is then coupled to the formation, the formation is fractured with fluid, and acoustic events in the formation are detected with the sensor.

  • Patent number: 7562712
    Abstract: A tool is actuated in a well based on one or more issued commands being interpreted and implemented by the apparatus. The apparatus comprises a power generation module that multiplies pressure delivered downhole to enable actuation of the tool without requiring delivery of the higher actuation pressure along the entire wellbore. An actuation module may be used in combination with the power generation module to control operation of the power generation module in response to command signals sent downhole.

  • Patent number: 7530392
    Abstract: A method and system for the production of a gas hydrate including the steps of drilling into a subterranean gas hydrate formation and at least partially depressurizing the gas hydrate formation to permit separation of gas and water from the hydrate form. The gas and water is then pumped from the formation and recovered from the well. At least a portion of water pumped from the well is water that is introduced into the well from the surface or reintroduced by a feed back loop from the production operation.

  • Patent number: 7458420
    Abstract: A system and method is provided to measure a pressure or other characteristic at a source (e.g. a hydraulic power supply) and in or near a downhole tool. A comparison of the measurements is then made to verify that the system is operating according to desired parameters. In specific applications, the comparison can be made to ensure the supply of hydraulic fluid is reaching the downhole tool.

  • Patent number: 7311154
    Abstract: A completion assembly has one or more control lines. The control lines can develop differing degrees of slack depending on the completion assembly configuration and also on the particular use of the completion assembly. A line slack compensator cooperates with the completion assembly to provide or remove slack in one or more control lines as necessary for a given operation and a given completion assembly.

  • Patent number: 7281577
    Abstract: One aspect of the present invention is a system and method to measure a pressure or other measurement at a source (e.g. a hydraulic power supply) and in or near a downhole tool and compare the measurements to verify that, for example, the supply is reaching the tool. Another aspect of the present invention is a system and method in which a gauge is positioned within a packer. Yet another aspect of the invention relates to a gauge that communicates with the setting chamber of a packer as well as related methods. Other aspects and features of the system and method are also described. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Patent number: 7128155
    Abstract: A cutting device cuts one or more downhole control lines such that the cut ends of the one or more control lines will not interfere with subsequent fishing operations. The cutting device comprises a mandrel, a cutting sleeve and a housing supported on a tubing. Movement of the tubing induces relative motion of the cutting sleeve to cut the one or more control lines.
