Devices, systems, and methods for selectively engaging downhole tool for wellbore operations

A device for deployment into a wellbore, the device comprising:

• an actuation mechanism comprising:
• a first housing having defined therein a first chamber;
• a piston having a first end and a second end, the first end of the piston extending into the first chamber, the piston being in sealing engagement with the first housing and configured to be slidably movable axially relative to the first housing, the piston having defined therein an inner flow path extending between the first end and the second end;
• a second housing having defined therein a second chamber, the second housing being fixedly coupled to the second end of the piston;
• a valve in communication with the inner flow path for controlling fluid communication between the first and second chambers via the inner flow path;
• and
• a piercing member configured to open the valve,
• the device being actuable to transition from an inactivated position to an activated position, wherein:
• in the inactivated position, the first chamber is filled with a first fluid, the first fluid being a substantially incompressible fluid to thereby restrict axial movement of the piston relative to the first housing;
• the second chamber is filled with a second fluid, the second fluid being more compressible than the first fluid;
• and the valve is intact to block fluid communication between the first and second chambers;
• and
• in the activated position, the valve is opened by the piercing member;
• at least some of the first fluid flowed to the second chamber via the inner flow path;
• and the piston moved axially relative to the first housing such that the first end of the piston extends further into the first chamber.

A method comprising:

• deploying a device into a wellbore, the device having:
• a first fluid chamber filled with a first fluid;
• a second fluid chamber filled with a second fluid, the second fluid being more compressible than the first fluid;
• a piston having a first end, a second end, and an inner surface defining an inner flow path extending from the first end to the second end, the first end extending into the first fluid chamber, the piston being stationary relative to the second fluid chamber and configured to be slidably movable axially relative to the first fluid chamber;
• a burst disk blocking fluid flow through the inner flow path to restrict fluid communication between the first and second fluid chambers;
• an exploding foil initiator;
• a propellant and
• a piercing member;
• activating the exploding foil initiator;
• initiating, by the exploding foil initiator, the propellant;
• driving, by the propellant, the piercing member into the burst disk to rupture the burst disk to unblock the inner flow path;
• receiving, by the second fluid chamber, at least some of the first fluid from the first fluid chamber via the inner flow path, thereby equalizing pressures in the first and second fluid chambers and moving the piston axially relative to the first fluid chamber.
