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, each sample having a same bit length; arranging the samples into a plurality of packets; compressing the plurality of packets by varying a time interval between transmissions of at least some of the packets; and transmitting the compressed packets.
Claims22
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, each sample having a same bit length;
- compressing at least some of the samples in selected packets before arranging such compressed samples into packets;
- arranging the samples into a plurality of packets;
- computing packet efficiency for a packet of the plurality of packets before computing the time intervals between the transmissions of the packets;
- and
- transmitting the plurality of packets by varying time intervals between transmissions of the packets.
