  • Publication number: 20150218937
    Abstract: A system and method for downhole signal enhancement. The system includes a downhole tool having one or more sensors coupled thereto. The one or more sensors may measure internal pressure and one or more parameters selected from the group consisting of external pressure, pressure sensor temperature, weight on bit, torque on bit, bending moment, roll gyro, tangential acceleration, radial acceleration, and axial acceleration. A noise estimator may be coupled to the downhole tool and estimate a downhole noise component in the one or more parameters. A telemetry modulator may be coupled to the downhole tool and generate a signal that includes the estimated downhole noise component and a telemetry component. The downhole noise component in the signal may be reduced based at least partially upon the estimate.

  • Publication number: 20150109140
    Abstract: A modem is described having a transceiver assembly, a non-transitory processor readable medium coupled to the transceiver assembly, transceiver electronics coupled to the transceiver and the non-transitory processor readable medium, and a power supply supplying power to the transceiver assembly and the transceiver electronics. The transceiver electronics are configured to calculate a size of an output bit stream based on an encoding scheme to encode for transmission data stored in the non-transitory processor readable medium, decimate the data if the size of the output bit stream exceeds a predetermined size, recalculate the size of the output bit stream, after decimation of the data, based on the encoding scheme to encode for transmission the decimated data, and encode the data using the encoding scheme.

  • Patent number: 8866633
    Abstract: The present disclosure relates to a method to determine a clock signal when separate clocks are used. In one embodiment, a disciplined clock system comprising an update subsystem and a synthesis subsystem is provided. A first clock phase estimate is provided to the update subsystem and used, along with the update subsystem, to determine a frequency offset estimate and a phase offset estimate. The clock signal is determining using the frequency offset estimate, the phase offset estimate, and the synthesis subsystem. Alternatively, two clocks can be synchronized by generating a signal associated with a first clock; modulating the signal; transmitting the modulated signal; receiving the modulated signal by a receiver associated with a second clock; correlating the received signal; determining the time of arrival of the received signal; determining the time difference between the two clocks; and synchronizing the two clocks.

  • Publication number: 20140229113
    Abstract: Compression of multidimensional sonic data is disclosed. Example methods disclosed herein to compress input multidimensional sonic data include decorrelating the input multidimensional sonic data to determine decorrelated multidimensional sonic data. In some such examples, the input multidimensional sonic data has a plurality of dimensions corresponding to a respective plurality of azimuthal directions from which the input multidimensional sonic data was obtained. In such examples, the decorrelated multidimensional sonic data is decorrelated among the plurality of dimensions of the input multidimensional sonic data. Such example methods also include processing the decorrelated multidimensional sonic data to determine compressed data representative of the input multidimensional sonic data.

  • Patent number: 8749398
    Abstract: A method for synchronizing a clock in a device at the Earth's surface with a device disposed in a wellbore includes generating a time datum for a signal generated at at least one of the surface and in the wellbore proximate an end of the pipe string. A time delay is determined between detection of the signal at the at least one repeater and retransmission of the signal from the at least one repeater. The time datum is appended with a signal corresponding to the time delay. The retransmitted signal is detected at the other of proximate the end of the pipe string and at the surface.

  • Publication number: 20130021166
    Abstract: To produce a desired telemetry signal, the desired telemetry signal is first determined and then decomposed into two or more component signals. For each component signal, commands are sent to an individual modulator. The individual modulators each produce individual signals according to their received commands. The individual signals from each individual modulator are combined to produce the desired telemetry signal, or the individual signals from each individual modulator are allowed to combine to produce the desired telemetry signal. A telemetry system that produces such desired telemetry signals includes an uplink transmitter/receiver pair, a downlink transmitter/receiver pair, or both pairs, wherein each uplink transmitter and each downlink receiver is disposed in a wellbore.

  • Publication number: 20120112924
    Abstract: Systems and methods provide wireless power and actuation of a downhole component within a borehole formed in a formation. The systems and method have a first downhole component positioned within the borehole and connected to and/or in communication with a power source. A wireless transmitter is electrically connected to the first component and is adapted to wirelessly transmit electrical power. A second downhole component is in communication with the wireless transmitter to receive the electrical power from the wireless transmitter. The second component is actuated upon receiving the electrical power to perform a task related to the borehole or formation about the borehole.
