Abstract:
This disclosure relates to system and method for delaying actuation using a destructible impedance device. In one embodiment, a delayed actuating system can comprise a base pipe comprising a first portion of an orifice, a sliding sleeve around the base pipe, the sliding sleeve comprising a second portion of said orifice, further said sliding sleeve maneuverable into a first position, wherein said first portion of said orifice rests at least partially over said second portion of said orifice, a second position, a distance away from said second position. Further, the delayed actuating system can comprise a biasing device biasing the sliding sleeve toward the second position, and a destructible impedance device at least partially in side said orifice, the destructible impedance device preventing the sliding sleeve from leaving the first position.
