Abstract: A method for locating and retrieving a line, tube or conduit (“line”) disposed in a well includes moving an intervention tool into a part of the well wherein the line is accessible to the tool when the tool is conveyed into the well from within a first tubular string. A first gripper arm is rotated in a first direction around an inner circumference of the first tubular string by operating a first motor in the tool until the first gripper arm contacts the line. A second gripper arm is rotated in a second direction opposed to the first direction around the inner circumference until the second gripper arm contacts the line by operating the first motor in a same direction as for rotating the first gripper arm. The first gripper arm and the second gripped arm are retracted to move the line toward the intervention tool.

Abstract: An apparatus for cutting sections of a wellbore tubular includes a housing shaped to enable movement along an interior of the tubular. The housing has an upper end arranged to connect to a conveyance and a lower end comprising a guide. Cutting materials are disposed in the housing and arranged to cut the wellbore tubular in two, longitudinally spaced apart circumferential cuts and at least one longitudinal cut extending between the circumferential cuts. The cutting materials are arranged to create the circumferential cuts simultaneously or with a time delay chosen to optimize energy created when cutting. A method for cutting wellbore tubulars includes positioning the apparatus at a selected position in the wellbore and actuating the cutting materials.

Abstract: A method for thermally insulating a power cable or other temperature sensitive equipment from a wellbore tool comprising a heater. The wellbore tool is deployed at an end of the power cable in a well. A flow restrictor is deployed in an annular space between the heater and a wellbore tubular. The heater is axially spaced apart from the power cable such that the heater is disposed on one side of the flow restrictor and a connection to the power cable is disposed on another side of the flow restrictor. A thermal insulator is introduced into the annular space on the one side of the flow restrictor and the heater is operated.

Abstract: A method for modifying an element on a section of wellbore tubular includes positioning a wellbore intervention tool at a first location on the tubular, operating a penetration device to remove the element and create an orifice on the section of wellbore tubular, and operating an installation device to install a replacement element in the orifice.

Abstract: A plug and abandonment wellbore intervention technology to longitudinal and circumferential cut a wellbore tubular in the same wellbore intervention, followed by dropping the cut sections into the wellbore below the location of the lower circumferential cut, so that access to an external tubular is possible for e.g. cement bond logging, placement of barrier material, removal of external tubular, etc.

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.

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.

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.

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.

Abstract: A wellbore pump includes a receptacle for a pump formed into a wellbore production tubing. A pump includes a seal engageable with an interior surface of the receptacle. The seal has a pump rod passing sealingly through the seal. The pump rod has a piston in sealing engagement with an interior of the tubing on each side of the seal. A power fluid line is in hydraulic connection to an interior of the production tubing above and below the seal. A well fluid inlet port is disposed between one of the pistons. A longitudinally spaced apart check valve is disposed in the wellbore production tubing above an upper one of the pistons.

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.

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.
