Abstract:
1. A method for use in seismic data acquisition, comprising: disposing a plurality of seismic data acquisition modules in an array, wherein each seismic data acquisition module is operative to wirelessly communicate with at least one other seismic data acquisition module in said array to define a data transmission path for transferring seismic data from said array to a data collection unit; operating a first seismic data acquisition module and a second seismic data acquisition module in said data transmission path to acquire seismic data during a first acquisition time and a second acquisition time, wherein said first acquisition time is non-overlapping with said second acquisition time; sending a first data sample corresponding to seismic data obtained at said first seismic data acquisition module during said first acquisition time from said first seismic data acquisition module to one of a third seismic acquisition module and a data collection unit; receiving, subsequent to said sending, a second data sample from said second seismic data acquisition module at said first seismic data acquisition module, wherein said second data sample corresponds to seismic data obtained at said second seismic data acquisition module during said first acquisition time, and wherein said second data sample has a first time stamp corresponding to said first acquisition time; appending a third data sample from said first seismic data acquisition module to said second data sample, wherein said third data sample corresponds to seismic data obtained at said first seismic data acquisition module during said second acquisition time, wherein said third data sample has a second time stamp corresponding to said second acquisition time, wherein said first and second time stamps are different; and transmitting said second and third data samples to at least one of said third seismic data acquisition module and a data collection unit.
