Abstract: A downhole energy transmission system is described. The system can include a casing string having a number of casing pipe disposed within a wellbore, where the casing string has at least one wall forming a cavity. The system can also include a remote electrical device disposed within the cavity of the casing string at a first location. The system can further include a first stripline cable disposed on an outer surface of the casing string, where the first stripline cable transmits a first energy received from an energy source. The system can also include a second stripline cable disposed adjacent to the first stripline cable at the first location, where the second stripline cable is electrically coupled to the remote electrical device.

Abstract: A system for determining a characteristic of an oil well includes a signal source to generate an excitation signal during a first time duration and to generate a local oscillator signal during a second time duration. The system further includes a directional coupler, and a resonator disposed in an annulus of an oil well to receive the excitation signal through the directional coupler. The system also includes a mixer to receive a resonator signal from the resonator through the directional coupler, to receive the local oscillator signal, and to generate a mixer output signal based on the resonator signal and the local oscillator signal. The system further includes a filter to filter the mixer output signal to produce an intermediate frequency signal having an intermediate frequency, and a processor to determine a pressure or a temperature experienced by the resonator based on the intermediate frequency signal and the excitation signal.

Abstract: A downhole energy transmission system is described. The system can include a tubing string having a number of tubing pipe disposed within an annulus formed by a casing string disposed within a wellbore, where the tubing string has at least one wall forming a cavity. The system can also include a remote electrical device disposed within the cavity of the tubing string at a first location. The system can further include a first stripline cable disposed on an outer surface of the tubing string, where the first stripline cable transmits a first electromagnetic directional traveling wave received from an energy source. The system can also include a second stripline cable disposed adjacent to the first stripline cable at the first location, where the second stripline cable is electrically coupled to the remote electrical device.

Abstract: A system, method and device may be used to provide power and monitor conditions in a borehole. Well tubing and casing act as a conductive pair for delivering power wirelessly to isolated zones defined between packer elements. Data signals are similarly transmitted. The packer elements include magnetic toroidal cores for power and signal transmission via inductively coupling.

Abstract: A system for applying power into a wellbore. The system can include a casing, a tubing string, a first and second isolator sub, a power source, and an electrical device. The casing has a first cavity running therethrough. The tubing string is disposed within the first cavity without contacting the casing, where the tubing string has a second cavity running therethrough. The first isolator sub is mechanically coupled to the tubing string and positioned between the neutral section and the power-transmitting section of the tubing string. The power source is electrically coupled to the power-transmitting section of the tubing string below the first isolator sub. The second isolator sub is mechanically coupled to the tubing string and positioned between the bottom neutral section and the power-transmitting section of the tubing string. The electrical device is electrically coupled to a bottom end of the power-transmitting section of the tubing string.
