Abstract: A device, system, and methods of power generation in situ in a hydrocarbon well are disclosed. A power generator for deployment in a hydrocarbon well tubular may comprise a housing adapted for deployment within a hydrocarbon well tubular; a mechanical to electrical power converter disposed at least partially within the housing, the mechanical to electrical power converter adapted to create an electric current when physically stressed; and a current converter operatively coupled to the mechanical to electrical power converter. Devices may be deployed downhole and operatively coupled to the power generator for their electrical power. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of meaning of the claims.

Abstract: A device, system, and methods of use for wireless transmission of a detected parameter obtained from inside a wellbore is disclosed. The wireless device comprises an acoustic wireless transceiver and a selectively expandable acoustic coupler operatively in communication with the acoustic wireless transceiver, the acoustic coupler adapted to physically couple the acoustic wireless transceiver with an interior of a tubular and acoustically transmit and/or receive data. The wireless monitoring device is deployed through a tubular to a predetermined position within the tubular, a predetermined portion physically coupled to the tubular once the monitoring device reaches the predetermined position, and data transmission acoustically coupled between the monitoring device and a remote receiver through the tubular.
