Abstract
A well bore completion tool includes an accelerometer having an accelerometer output representative of acceleration of the well bore completion tool. The well bore completion tool includes a signal conditioning device coupled to the accelerometer output and producing a conditioned accelerometer output. The well bore completion tool includes an uplink coupled to the conditioned accelerometer output.
Claims20

A system comprising:
- a completion string deployed in a borehole;
- a completion tool included in the completion string;
- an accelerometer included in the completion tool;
- a valve coupled to the completion string and operable to allow fluid communication between the completion string and a formation adjacent the borehole;
- a processor coupled to the accelerometer and to the valve;
- and
- the processor programed to adjust the valve in response to data regarding acceleration of the completion tool received from the accelerometer.

A method comprising:
- measuring acceleration with an accelerometer in a first completion tool in a first zonal control assembly in a completion string deployed in a borehole to produce an accelerometer signal;
- determining a vibration parameter for the first zonal control assembly adjacent the first completion tool based on the accelerometer signal;
- and
- adjusting a point of control in a second zonal control assembly in the completion string in response to determining the vibration parameter for the first zonal control assembly.
