Abstract
Abstract A remotely actuated rupture disk can be ruptured upon the receipt of a predetermined signal. The disk can be placed in a port, thereby separating different pressure regions. For example, if the disk is placed in a downhole tool assembly, the disk might be used to isolate a specific chamber from the annular well pressure. An actuation signal can be transmitted down the well's annulus and is received by a receiver coupled to the rupture disk. The received signal is conditioned to trigger a destructive material which then ruptures the disk, connecting the two pressure regions.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
67 words
A method of triggering a rupture event for at least one rupture disk coupled to a downhole tool on a string in a well, the method comprising: (a) transmitting a signal to a receiver in the well wherein the receiver is coupled to the at least one rupture disk, wherein said signal is acoustic, electromagnetic, or seismic; (b) triggering the rupture event in response to the signal.
Claim 2
Independent Claim
67 words
A method of triggering a rupture event for at least one rupture disk coupled to a downhole tool on a string in a well, the method comprising: (a) transmitting a signal to a receiver in the well wherein the receiver is coupled to the at least one rupture disk, wherein said signal is acoustic, electromagnetic, or seismic; (b) triggering the rupture event in response to the signal.
