摘要： A method to measure borehole Stoneley wave slowness and its associated tool-corrected dispersion curve. The method for measuring borehole Stoneley wave slowness may comprise gathering waveforms, conditioning waveforms, identifying slowness constraints, computing a time-slowness mask, computing a coherence map from differential phase time semblance, processing a two-dimensional time-slowness map, determining slownesses from a one-dimensional variable density log, and tracking time pick from a two-dimensional map. The method may further comprise identifying one or more of coherence, power, instantaneous frequency, signal-to-noise ratio, or error bars from the two-dimensional time-slowness map. The method may further computing a spline interpolation locally around the pick from the one-dimensional variable density log to produce a final data product.

摘要： A technique facilitates efficient data transfer during a drilling operation. The drilling operation involves deploying a drill string downhole and rotating a drill bit to cut a borehole into a subterranean formation. While the drill bit is on bottom, real-time sensor data is transmitted to a surface location or other suitable location via a data transmission system. The transmission of current or real-time sensor data is stopped when the drill bit is moved off bottom. While the drill bit is off bottom, previously recorded data is sent uphole.

摘要： In some embodiments, methods, apparatus, and systems may operate to launch acoustic waves along a first acoustic path length from an acoustic transducer. The apparatus receives a reflected signal in response to each acoustic wave, each reflected signal including at least one echo. The reflected signal is decomposed, using a time-frequency decomposition method with basis functions, into a wavelet associated with each echo. Parameters describing each associated wavelet are determined and a borehole evaluation or pipeline inspection is performed based on the parameters.

摘要： Methods and apparatus for transmitting power and data along a metal pipe using wideband acoustic waves. Arrangements use shear-horizontal waves, transmitting narrowband signals for power applications and wideband signals for communications having a bandwidth greater than the coherence bandwidth of the acoustic-electric channel. Chirp wave signals, direct sequence spread signals, and on-off keying are used. Acoustic-electric channels include wedges fixed to a pipe or other substrate, transducers fixed to the wedges, and electronics linked to each transducer for sending and receiving power and signals. Matching networks, rectification circuits, and non¬ coherent signal reception methods may be used.
