  • Patent number: 10400565
    Abstract: A method for fracturing a wellbore in a formation, including positioning one or more bidirectional rotary sleeves on tubular members into the wellbore; engaging a unidirectional rotary source in a first position with a first bidirectional rotary sleeve of the one or more bidirectional rotary sleeves; operating the unidirectional rotary source to rotate the first bidirectional rotary sleeve in a first rotational direction to open at least one port in the first bidirectional rotary sleeve for providing an open fluid pathway between the first bidirectional rotary sleeve and the formation; pumping fluid through the tubular members and through the opened port to fracture the formation; engaging the unidirectional rotary source in a second position with the first bidirectional rotary sleeve; and operating the unidirectional rotary source to rotate first bidirectional rotary sleeve in a second rotational direction to close the at least one port in the first bidirectional rotary sleeve.

  • Publication number: 20190242216
    Abstract: A pressure response fracture port tool and method for its use reliably provides a noticeable indication at surface to an operator as to when the flow port is opened. The tool includes an outer housing and a sliding sleeve which resides within the outer housing. The outer housing has a first and second set of flow ports. The inner mandrel moves between a first position and a third position to expose the flow ports to the wellbore. The first set of flow ports, with its smaller area relative to the second set of flow ports, creates a noticeable pressure increase or spike that can be observed at surface when exposed to the wellbore. The second set of flow ports creates a noticeable pressure drop when it is exposed to the wellbore.

  • Patent number: 10303753
    Abstract: The present invention provides copybook flat data conversion with inline transformation. Specifically, a streaming intermediary formatted data message is generated as a result of converting/transforming a flat file format (non-XML (Extensible Markup Language) format), such as raw fixed-length field COBOL (Common Business-Oriented Language) copybook format or the like. The streaming intermediary format is not fully held in memory, but rather is directly transformed/converted, using XSLT (Extensible Stylesheet Language Transformations) processing, into a target format, such as structured XML or the like. By directly streaming the intermediary format to the XSLT process without holding the entire data message in memory, the present invention utilizes less memory and, as such, less memory is needed to be reclaimed.

  • Publication number: 20070240873
    Abstract: A surge chamber assembly (70) for use in a wellbore includes a housing (80) having one or more openings (112), a surge chamber (100) and a combustion chamber (98). The openings (112) provide fluid communication between the exterior (82) of the housing (80) and the surge chamber (100). A sleeve (114) is slidably positioned within the housing (80) and has a first position wherein fluid communication through the openings (112) is prevented and a second position wherein fluid communication through the openings (112) is allowed. A combustible element (124) is positioned in the combustion chamber (98) such that combusting the combustible element (124) generates pressure in the combustion chamber (98) that actuates the sleeve (114) from the first position to the second position.

  • Patent number: 6854549
    Abstract: An electronic engine speed control system is used on a work machine utilizing an engine with a governor control movable between a plurality of positions. The governor control is operated by an operator so that a desired engine speed may be selected for driving a plurality of wheels through a transmission. The transmission is specifically controlled to obtain a desired ground speed independent of the selected engine speed. The engine speed control system includes an electronic control module. An operator switch is connected to the control module and is movable to a set position which sends an input signal with a desired engine speed value corresponding to a selected engine speed to the control module. An engine sensor is connectable between the engine and the control module for sensing the speed of the engine and sending an input signal with an actual engine speed value to the control module.
