  • Patent number: 10756575
    Abstract: A wireless power transfer system may provide coils that are respectively position on upper and lower ends of a pipe to allow power to be wirelessly transferred. Additionally, the system may also provide a soft ferrite layer placed on the upper and lower pipe sections to enhance the magnetic coupling so that the wireless power transfer efficiency can be maintained at a sufficient level when the coil separation is relatively large. Notably, this ferrite layer may span most or the entirely of the region between the coils to further enhance performance. In some cases, a ferrite core may be position between the coils and the pipe as well. In some cases, the pipe may include a tool section that may be non-conductive or results in a discontinuity in the ferrite layer. However, the setup of the system allows power to be wirelessly transferred despite such discontinuity.

  • Patent number: 10663503
    Abstract: A polyphase electric power supply system via which powerline communications are set up between a transmitter and a receiver. The transmitter: detects a first zero-crossing of an alternating electrical signal on a phase connected to the transmitter; determines a first instance when the transmitter is expected to transmit a dataset; determines a first time difference between the first zero-crossing and the first instance; includes in the data set information of the phase to which the transmitter is connected, when the first time difference is below a predefined threshold. The receiver: detects a second zero-crossing of the alternating electrical signal on the phase connected to the receiver; detects a second instant when the receiver receives the data set; determines a second time difference between the second zero-crossing and the second instant; determines the phase connected to the receiver, from the second time difference and the transmitter phase information.

  • Patent number: 10598816
    Abstract: Disclosed embodiments include systems and methods of correcting induction logging data for relative dip. Initial induction logging data is measured at a plurality of frequencies. One example embodiment includes displaying dip corrected data for a plurality of different relative dip angles, which may further be displayed with a qualitative indicator displayed over many depth samples for selecting or validating a correct relative dip angle. The data may be iteratively processed using an automated relative dip correction algorithm and analyzed by the user to obtain and apply the best relative dip correction angle to induction logging data. Once dip corrected, the induction logging data can be used with resistivity methodologies generally designed for instances where no dip is present in the formation under analysis.
