摘要： 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.

摘要： A system and method for selectively locking open or close a gravel pack-circulating sleeve is disclosed. The sleeve is movably coupled to a first chamber containing a fluid. The first chamber is fluidly connected to a second chamber through a fluid flow controller. Shifting of the sleeve between open and closed positions is resisted by a the fluid flow controller. The resistance to fluid flow can reduce or eliminate inadvertent shifting of the sleeve due to short bumps and small loads upon the sleeve. To overcome the resistance to fluid flow and to shift the sleeve, a continuous load can be applied to the sleeve.

摘要： Methods and apparatus are presented for removing a degradable barrier plug positioned in a downhole axial passageway. The degradable plug is initially isolated from fluid by at least one solid, non-degradable cover. A first electronic rupture disc assembly is actuated to open a passageway to the degradable plug. A second electronic rupture disc assembly is actuated to allow a fluid, such as water from a supply chamber, to flow into contact with the plug. The plug is substantially degraded, although the cover remains. A third electronic rupture disc assembly is actuated to bend and then cover the remaining solid cover, thereby opening the axial passageway and protecting later-introduced tools.
