Abstract: A subsea communication system includes addressable nodes in a wellbore and addressable nodes on a floor, where the nodes in the wellbore and on the floor are able to communicate wirelessly with each other, such as through a formation.

Abstract: Zonal isolation tools and methods of using same are described. The zonal isolation tools include a wellbore sealing member expandable by fluid pressure to contact a wellbore over an initial contact area, an inflation valve open during expansion of the sealing member to the initial contact area and closed upon the fluid pressure reaching a predetermined setting, a vent between the sealing member and a wellbore annulus adapted to open after the inflation valve is closed, and a compressive load imparted to the sealing member via a linear piston to achieve a sealing point at the leading edge of the sealing member. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A technique that is usable with a well includes using at least one downhole sensor to establish telemetry within the well. The sensor(s) are used as a permanent sensing device.

Abstract: A technique that is usable with a subterranean well includes communicating a wireless stimulus in the well. The technique includes actuating a valve in response to the communication. The valve has more than one controllable open position.

Abstract: A system and method enable telemetry between a downhole device located in a wellbore and an uphole device. Electrical signals are communicated between locations via at least one fluid carrying control line. The control line provides a path for fluid flow as well as for the transmission of electrical signals. Thus, electrical signals may be transmitted from one location to another within a wellbore without separate electrical wires or cables.

Abstract: A plunger lift apparatus includes wellhead equipment containing a receiver, a conduit extending from the wellhead equipment into a wellbore, and a plunger to be run through the conduit to a downhole location in the wellbore. The plunger includes at least a sensor to measure a downhole parameter, and a plunger is adapted to communicate the measured downhole parameter to the receiver.

Abstract: A system and method is provided for sensing a variety of parameters in well-related environments. A skin sensor is deployed in downhole applications to obtain data used in analyzing well characteristics.

Abstract: A subsea communication system includes devices in a wellbore and devices on a floor, where the devices in the wellbore and on the floor are able to communicate wirelessly with each other, such as through a formation.

Abstract: A technique that is usable with a subterranean well includes communicating a wireless stimulus downhole in the well and actuating a casing conveyed tool in response to the communication.

Abstract: The invention is a sealing system, such as a packer, that is used in a wellbore to seal against an exterior surface, such as a casing or open wellbore. The sealing system includes a swellable material that swells from an unexpanded state to an expanded state thereby creating a seal when the swellable material comes into contact with a triggering fluid.

Abstract: The invention is a method of packaging an electronic tag. The method includes heating the electronic tag to remove contaminants from an internal volume. The internal volume is filled with a potting material and is hermetically sealed within an outer shell. The invention is a method of positioning an electronic tag in a tubular member. The method includes positioning an electronic tag in a slot formed in an inner wall of the tubular member. The slot is filled with a potting material that adhesively bonds the electronic tag to the slot. The invention is an electronic tag apparatus. The apparatus comprises a slot formed at a selected azimuthal location in an inner wall of a tubular member. An electronic tag is disposed in the slot. A potting material is disposed in the slot, and the potting material forms a barrier between the electronic tag and the inner wall of the tubular member and adhesively bonds the electronic tag to the slot.
