  • Patent number: 10370919
    Abstract: A wellbore intervention tool includes a housing and a means for locking the housing at a selected position inside a first wellbore pipe. The tool includes means for penetrating the first wellbore pipe extensible from the housing. The means for penetrating includes means for measuring an amount of extension thereof or an amount of force exerted thereby such that the means for penetrating is controllable to penetrate the first wellbore pipe without penetration of a second wellbore pipe in which the first wellbore pipe is nested.

  • Patent number: 10370920
    Abstract: A wellbore intervention tool for use in penetrating an obstruction in a wellbore includes a cutting tool having at least one rotating cutter member for penetrating the obstruction. A displacement mechanism coupled to the cutting tool sets and adjusts a cutting position of the cutting tool relative to a tool axis. A sweeper coupled to the displacement mechanism deflects the displacement mechanism about the tool axis, and the cutting tool is deflected with the displacement mechanism.

  • Publication number: 20190055815
    Abstract: A method for operating a pressure operated device in a wellbore includes conducting pressurized gas to a power fluid inlet port of a valve at a first pressure. The first pressure is selected to cause a shuttle in the valve to be positioned to enable flow of the pressurized gas through the valve to a power fluid flow port in communication with a power fluid inlet of the pneumatic device. Pressure of the pressurized gas is increased to a second pressure greater than the first pressure, whereby the shuttle moves to close the power fluid inlet port to flow and to vent the power fluid flow port to ambient pressure in the wellbore.

  • Patent number: 10107067
    Abstract: Methods for sealing a wellbore include placing a barrier material within an annular space between a wellbore tubing and a wellbore casing, wherein a seal is placed across or below openings in the wellbore tubing at at least one location above a lowermost tubing to annulus opening. In some embodiments, an intervention tubing may be used to insert the barrier material into successively exposed ones of the annulus openings, whereby no seal sleeve is needed.

  • Publication number: 20180187789
    Abstract: An apparatus is for controlling a fluid flow. The apparatus has a valve provided with a valve adjuster for controlling a fluid flow through the valve. The valve has a fluid inlet in fluid communication with a fluid inlet conduit, and a fluid outlet in fluid communication with a fluid outlet conduit, for flowing fluid through the valve. The apparatus further has an actuator device capable of undergoing a change in shape, the change in shape of the actuator device providing via a connecting member an attenuated or amplified displacement of a fixation point connected to the valve adjuster, when compared to the change in shape of the actuator device.

  • Patent number: 9926747
    Abstract: Signal communications at a drilling system generally includes communicating upwards or downwards from the rig floor. For example, signal communications upwards may comprise the control of a cementing head operation (e.g., actuating cementing head). Signal communications downwards may comprise the activation of tools and their confirmation (e.g., hole opening tools, liner hangers, and packers). Actuation may be performed via umbilicals, for example, via pressure spikes or the dropping of balls, darts, or radio-frequency identification (RFID) tags. However, issues may arise wherein, for example, a ball may not properly land to close a circulation valve. As another example, a cementing head could be over 100 feet above the rig floor, which may make it difficult for signal communications via an umbilical. Accordingly, what is needed are techniques and apparatus for activation of tools and their confirmation by a remote communication system.

  • Patent number: 7963340
    Abstract: Disclosed herein is a temporary well isolation device, which is sealingly disposable in downhole tubing, and which has a housing with an axial passage. The temporary well isolation device also has frangible barrier element within the housing, where the frangible barrier element is sealingly engaged in the passage blocking fluid flow through the passage. The frangible barrier element bears a load from fluid pressure. The temporary well isolation device also has a disengageable constraint in contact with a frangible barrier element so as to redirect the load on the frangible barrier element from a first component of the load to a second component of the load, thereby preventing rupture of the frangible barrier element. Also disclosed herein is a method for disintegrating a frangible barrier element disposed in a passage of a temporary well isolation device.

  • Patent number: 7172029
    Abstract: The present invention is a packer for sealing an annular region in a wellbore. The packer includes a packing element which is held through bidirectional forces. The packer first comprises an inner mandrel. Disposed around the inner mandrel are three tubulars: (1) a top sleeve; (2) a bottom sleeve; and (3) a booster sleeve. A packing element is disposed circumferentially around the outer surface of the booster sleeve. The top sleeve and bottom sleeve each include an upper compression member which rides across the booster sleeve in order to compress the packing element. The packing element is expanded outward from the packer to engage a surrounding string of casing through compressive forces provided by the top and bottom sleeves. Thereafter, differential pressure applied above or below the packer acting on the packer element and booster sleeve may provide additional compression of the packer element.

  • Patent number: 7165622
    Abstract: A packer, and operation of the same, which forms elastomeric seals and non-elastomeric seals. The packer may be constructed from a non-elastomeric tubular core having a frustoconical shaped inner diameter. The outer diameter of the core may be substantially smooth and carry one or more elastomeric sealing elements. The packer is set by causing the diametrical expansion of the tubular core. The construction of the tubular core is preferably such that its diametrical expansion causes the formation of radial raised portions (upsets) on the outer surface. These raised portions form the non-elastomeric seals and also prevent extrusion of the elastomeric sealing elements.
