  • Patent number: 10613139
    Abstract: Embodiments disclosed herein are directed towards systems and methods for electric current leakage detection in a land seismic system. Embodiments may include generating at least one test signal using a digital to analog converter “DAC” circuitry, wherein the DAC circuitry includes an output operatively connected to earth ground. Embodiments may further include alternately grounding a positive path to an analog to digital converter “ADC” circuitry during a first time window and a negative path to the analog to digital converter during a second time window while measuring an ADC signal. Embodiments may also include determining an average amplitude of the first time window and the second time window and determining a leakage resistance based upon, at least in part, the average amplitude of the first time window and the second time window.

  • Publication number: 20190011586
    Abstract: A method can include receiving seismic data acquired by a sensor unit responsive to emission of seismic energy in a frequency sweep of a duration having a duration time; correlating the seismic data and individual portions of the frequency sweep that correspond to individual time windows to generate individual sets of correlated seismic data; for a common event, identifying a corresponding event time in each of the individual sets of correlated seismic data; and determining a clock drift time based at least in part on the event times.

  • Patent number: 9341724
    Abstract: An embodiment of the invention includes combining pseudorandom sweeps with an independent, or nearly independent, survey acquisition technique. Targeted design of pseudorandom sweeps can direct the majority of cross-correlation noise to lie outside key time-lags of the record (i.e., windows of interest). Embodiments of the invention are described herein.

  • Patent number: 8780670
    Abstract: An embodiment according to one or more aspects of the present disclosure for conducting a marine survey includes a survey spread comprising a plurality of receivers and an energy source that is towed along a selected course while a signal is emitted from an energy source. A plurality of receivers receive data comprising a detection sampling frequency and a survey sampling frequency. The survey sampling frequency is monitored to detect a cetacean vocalization and to position the cetacean at least while conducting the seismic survey. Pursuant to the location of the cetacean actions can be taken to protect the cetacean and to minimize disruptions in conducting the seismic survey.
