    摘要: Methods and apparatus to process time series data for propagating signals in a subterranean formation are disclosed. An example method described herein for processing measured data comprises receiving a time series of measured data obtained by sensing a propagating signal, the propagating signal having passed through a subterranean formation, transforming the time series of measured data to generate a time-frequency representation of the time series, and processing the time-frequency representation to at least one of reduce noise in the time frequency representation, or enhance a component of the propagating signal present in the time-frequency representation.

    摘要: Aspects of the inventions generally provide a method and apparatus for coupling a communication sub to a wired drill pipe. In one aspect, a surface of a coupler head is non threaded and configured to provide a retaining force. In another aspect, a coupler head is coupled to a body, and a support mechanism is coupled to the body and configured to secure the coupler head within a receiving end of the wired drill pipe. In another aspect, a method of placing a communication sub involves inserting the communication sub into the receiving end of the wired drill pipe, adjusting the position of the communication sub until an indication of signal communication between the communication sub and the wired drill pipe is observed, and after the indication of signal communication is observed, retaining the communication sub within the receiving end until removal of the communication sub is desired.

    摘要: Techniques are presented for determining the drift of a clock adapted for subsurface disposal. Seismic signals are transmitted through the subsurface medium from an uphole location at selected times, acoustic signals associated with the transmitted seismic signals are received with acoustic sensors at identified downhole locations. First and second transit times for acoustic signals received at an identified downhole reference location are determined using the clock. A time difference between the first and second signal transit times at the reference point is calculated to determine the clock drift.

    摘要: Methods and apparatus for modeling formations are disclosed. An example apparatus includes a source spaced from receivers. The source is to transmit a signal and the receivers are to receive at least a portion of the signal. The example apparatus also includes a processor to process waveform data associated with the signal by generating a parameter estimate used in an inversion of Stoneley dispersion to enable a Stoneley shear slowness to substantially correspond to a slow-shear slowness when the apparatus is at least partially positioned in a horizontal wellbore of a vertical transverse isotropy formation.
