Abstract
An apparatus includes an impervious body, a sealing element, an energy source, and a trigger. The impervious body is configured to prevent passage of fluid therethrough. The sealing element is disposed about the impervious body. The energy source is operationally connected to the sealing element. The trigger is configured to transfer energy from the energy source to the sealing element. The trigger is activated, at least in part, by receiving a signal transmitted through the impervious body.
Claims17
An apparatus comprising:
- an impervious body configured to prevent passage of fluid therethrough;
- a sealing element disposed about the impervious body;
- a hydraulic fluid reservoir operationally connected to the sealing element;
- an electronics compartment hydraulically connected to the hydraulic fluid reservoir;
- a pressure barrier between the hydraulic fluid reservoir and the electronics compartment;
- and
- a trigger configured to receive a signal from within an interior of the impervious body and open the pressure barrier;
- wherein opening of the pressure barrier permits movement of hydraulic fluid out of the hydraulic fluid reservoir and into the electronics compartment, allowing the sealing element to set.
A method comprising:
- providing an apparatus comprising:
- an impervious body configured to prevent passage of fluid therethrough;
- a sealing element disposed about the impervious body;
- an energy source operationally connected to the sealing element;
- and
- a hydraulic fluid reservoir operationally connected to the sealing element;
- a trigger configured to transfer energy from the energy source to the sealing element;
- wherein the trigger is activated, at least in part, by receiving a signal transmitted through the impervious body;
- wherein opening of the pressure barrier permits movement of hydraulic fluid out of the hydraulic fluid reservoir and into the electronics compartment, allowing the sealing element to set;
- introducing the apparatus into a wellbore;
- and
- providing the signal to the trigger through the impervious body, thereby causing the sealing element to set.

- a pressure barrier between the hydraulic fluid reservoir and the electronics compartment;
- and
- a trigger configured to receive a signal from within an interior of the impervious body and open the pressure barrier;
- a sleeve disposed within the interior of the impervious body such that movement of the sleeve relative to the impervious body creates the signal to the trigger;
- wherein opening of the pressure barrier permits movement of hydraulic fluid out of the hydraulic fluid reservoir and into the electronics compartment, allowing the sealing element to set.
