  • Patent number: 9696131
    Abstract: Compensation for a field-perturbing element in a magnetic tracking system for locating a probe is achieved by creating a reaction field model while the field-perturbing element is in known positions. A magnetic field location sensor is disposed between the field-perturbing element and magnetic field generators of the tracking system. Magnetic field readings from the location sensor and from a magnetic field sensor on the probe are taken while the field-perturbing element is present. The position of the field-perturbing element is estimated from the location sensor readings, and a predicted reaction field calculated from the reaction field model. A compensated measurement is obtained by subtracting the predicted reaction field from the field detected by the location sensor. The readings from the probe sensor are adjusted using the compensated measurement in order to calculate the true position of the probe.

  • Publication number: 20150047824
    Abstract: An actuation tool uses a lock that when released allows a moving magnet to move into position to repel another magnet. Alternatively a magnetic field can be triggered in a stationary magnet such as one delivered on wireline, for example, to accomplish tool actuation. The repelling force on the second magnet moves it away from a locking position to allow another lock to retract and release the stored potential energy, where the release of the potential energy creates kinetic energy to drive an actuation assembly to set the tool. In a preferred application the tool can be a liner hanger. The release device can be a selectively energized electromagnet or a solenoid that shifts at least one magnet into alignment with at least one second magnet so as to defeat the second magnet from effectively supporting dogs that retain the potential energy whose movement can set the tool.

The flow-driven generator comprises an impeller connected to a magnet assembly to rotate the magnet assembly when fluid flows past the impeller. This causes relative movement between the magnet assembly and an adjacent electrical coil assembly, the relative movement and magnetic coupling generating an electrical current in the coil assembly. This generated electrical current is used to power electrical devices within the pipe.

  • Publication number: 20140238662
    Abstract: An apparatus for reducing vibration in a downhole component includes: an electrically conductive auxiliary mass attached to the component and configured to vibrate in a direction corresponding to a direction of downhole component vibration and absorb a portion of the downhole component vibration; and a magnetic component configured to generate a magnetic field through the auxiliary mass having a direction at least partially perpendicular to the direction of auxiliary mass vibration, the magnetic field configured to induce a current in the auxiliary mass in response to auxiliary mass vibration. The apparatus has an auxiliary mass vibration frequency tuned relative to a selected natural vibration frequency of the downhole component to reduce vibration of the downhole component, the auxiliary mass vibration frequency based on a magnetic stiffness of the auxiliary mass, the magnetic stiffness based on a strength of the magnetic field and/or a resistance of the auxiliary mass.

  • Patent number: 8776883
    Abstract: A process for controlling the production of loose sand particles within an underground formation through the use of magnetic forces is provided. The loose sand particles are magnetized and then subjected to a magnetic field of sufficient strength such that the operator can control the movement of the loose sand particles within the underground formation. In some instances, the present invention can provide an efficient process for keeping the loose sand particles within the formation, and thereby prolonging the useful life of the downhole equipment. In other instances, the present invention can provide an efficient process for sweeping the loose sand particles out of the underground formation in a controlled fashion. The present invention includes at least three embodiments for magnetizing the loose sand particles, including direct magnetization, contacting the sand particles with a magnetizing reagent, and contacting the sand particles with paramagnetic nanoparticles.

  • Publication number: 20140174716
    Abstract: A petroleum well intervention winch system includes a high pressure confining housing for a drum for a rope to a tool string. The pressure confining housing has a connector with an aperture for the rope to a top of a tool string gate chamber on vertical bore BOP valves on a wellhead on the petroleum well. The rope runs through the aperture via a capstan to the drum. The capstan is driven by a first motor through a first high pressure proof magnetic coupling across a wall of the housing. The drum is driven by a second motor through a second high pressure proof magnetic coupling across the wall of the housing. The capstan is subject to a load tension from the rope and is provided with a hold tension on the rope from the drum. The second motor exerts a constant hold tension on the rope via the drum.

    Abstract: A hydrocarbon resource recovery system for a wellbore in a subterranean formation. The hydrocarbon resource recovery system may include a radio frequency (RF) source, and an antenna configured to be positioned within the wellbore and coupled to the RF source. The antenna may be coupled to the RF source and configured to generate a higher electric field strength region in the subterranean formation having a higher electric field strength and a lower magnetic field strength, and generate a higher magnetic field strength region in the subterranean formation having a higher magnetic field strength and a lower electric field strength. The antenna may have a tubular shape with a plurality of openings therein defining a hydrocarbon resource recovery capacity adjacent the higher electric field strength region that is different than a hydrocarbon resource recovery capacity adjacent the higher magnetic field strength region.
