Abstract
A system is described that is positionable downhole in wellbore for determining a parameter of a downhole tool. The system includes a tubing subassembly and a signal generator positioned in the tubing subassembly for outputting, in response to being covered or uncovered by a detectable portion of a downhole tool, a detectable signal for determining a parameter of the downhole tool.
Claims17
A system positionable downhole in wellbore, the system comprising:
- a tubing subassembly;
- an acoustic sensor that is operable to detect sound waves reflected from an actuatable member or detectable portion of a downhole tool;
- and
- an acoustic signal generator positioned in a compartment of the tubing subassembly for (i) receiving a signal from the acoustic sensor that indicates that the signal generator is uncovered by the actuatable member or detectable portion of the downhole tool and (ii) responsively outputting a detectable signal usable to determine a parameter of the downhole tool in response to the signal from the acoustic sensor;
- wherein the parameter of the downhole tool includes a first parameter and a second parameter, the first parameter indicates the downhole tool is in a set state or a released state and the second parameter indicates the downhole tool is in a locked state or an unlocked state.

A downhole notification method comprising:
- detecting an acoustical detection event by an acoustic sensor that is operable to detect sound waves reflected from an actuatable member or detectable portion of a downhole tool, the acoustic sensor communicatively coupled to an acoustic signal generator positioned within a compartment in a tubing subassembly, the acoustical detection event corresponding to an uncovering of the acoustic signal generator by the actuatable member or detectable portion of the downhole tool;
- and
- generating a detectable signal, by the acoustic signal generator usable to determine a parameter of the downhole tool, in response to receiving a signal from the acoustic sensor, the signal indicating the acoustic sensor detected the acoustical detection event;
- wherein the parameter of the downhole tool includes a first parameter and a second parameter, the first parameter indicates the downhole tool is in a set state or a released state and the second parameter indicates the downhole tool is in a locked state or an unlocked state.

A system positionable downhole in wellbore, the system comprising:
- a tubing subassembly having a compartment;
- an acoustic signal generator, for determining a parameter of a downhole tool, the acoustic signal generator including a signal generation device and an acoustic sensor that is operable to detect sound waves reflected from an actuatable member or detectable portion of the downhole tool;
- wherein:
- the acoustic sensor is positioned in the compartment for detecting the compartment being uncovered by the actuatable member or detectable portion of the downhole tool;
- the signal generation device is operatively coupled to the acoustic sensor for (i) receiving a signal from the acoustic sensor that indicates that the compartment with the acoustic sensor is uncovered by the actuatable member or detectable portion of the downhole tool and (ii) responsively generating an acoustic signal or an electrical signal usable to determine the parameter of the downhole tool;
- and
- the parameter of the downhole tool includes a first parameter and a second parameter, the first parameter indicates the downhole tool is in a set state or a released state, and the second parameter indicates the downhole tool is in a locked state or an unlocked state.
