    Abstract: A magnetic system for determining an operating position of a downhole tool. The system includes an array of magnets operable to produce a magnetic field that is operably associated with a stationary component of the downhole tool. A moveable component of the downhole tool has at least first and second positions relative to the stationary component. In the first position, the moveable component has a first degree of interference with the magnetic field. In the second position, the moveable component has a second degree of interference with the magnetic field. A magnetic field detector is operable to be run into the wellbore and moved relative to the downhole tool such that the position of the moveable component relative to the stationary component is determined by detection of a magnetic signature produced by the moveable component and the array of magnets.

    Abstract: A method of activating a downhole tool can include configuring the tool having an electrical power source, an electrical load, control circuitry which controls the electrical load, and a switch which selectively permits current flow between the power source and the circuitry, and generating electricity, thereby causing the switch to permit current flow between the power source and the circuitry. A downhole tool can include an electrical power source, an electrical load, control circuitry, a switch which selectively permits current flow between the power source and the circuitry, and a generator. Another method can include displacing a fluid and/or an object at the tool, generating electricity in response to the displacing, permitting current flow between an electrical power source and a control circuitry in response to the generating and, after the permitting and in response to detection of a predetermined signal, the circuitry causing activation of an electrical load.

    Abstract: A wellbore isolation device comprises a first material and pieces of a second material, wherein the first material: is a metal or a metal alloy; forms a matrix of the portion of the wellbore isolation device; and partially or wholly dissolves when an electrically conductive path exists between the first material and the second material and at least a portion of the first and second materials are in contact with the electrolyte, wherein the pieces of the second material: are a metal or metal alloy; and are embedded within the matrix of the first material; wherein the first material and the second material form a galvanic couple and wherein the first material is the anode and the second material is the cathode of the couple. The isolation device can also include a bonding agent for bonding the pieces of the second material into the matrix of the first material.

    Abstract: A wireless actuation system comprises a transmitter, an actuation system comprising a receiving antenna, and one or more sliding members transitional from a first position to a second position. The transmitter is configured to transmit an electromagnetic signal, and the sliding member prevents a route of fluid communication via one or more ports of a housing when the sliding member is in the first position. The sliding member allows fluid communication via the one or more ports of the housing when the sliding member is in the second position, and the actuation system is configured to allow the sliding member to transition from the first position to the second position in response to recognition of the electromagnetic signal by the receiving antenna.
