First Claim
Patent Images
1. A method of acquiring seismic data, comprising:
- receiving seismic signals at one or more sensors;
sampling the received seismic signals into a plurality of samples;
arranging the plurality of samples into a plurality of packets;
transmitting the plurality of packets; and
reducing a coherent noise by making a transmission noise non-periodic by selectively varying time intervals between transmissions of the packets, wherein the transmission noise is from the transmission of the plurality of packets.

Abstract
A method of acquiring seismic data. The method includes receiving seismic signals at one or more sensors; sampling the received seismic signals into a plurality of samples, compressing at least some of the samples in selected packets before arranging the compressed samples into packets; arranging the samples into a plurality of packets; computing packet efficiency for a packet of the plurality of packets; transmitting the plurality of packets by varying time intervals between transmissions of the packets.
