Abstract
A seismic data acquisition method is provided that includes receiving seismic signals at a sensor; sampling the received seismic signals into a plurality of samples, each sample having a selected number of bits (“bit length”); arranging the samples in packets, wherein some of the packets include one or more compressed samples; and transmitting the packet to a remote unit.
Claims21
A method of acquiring seismic data, comprising:
- receiving seismic signals at a sensor from an earth formation;
- creating a plurality of samples from the received seismic signals, each created sample having a same bit length;
- arranging the plurality of samples in packets, wherein at least some of the packets include one or more compressed samples;
- and
- transmitting the packet to a remote unit.
2 more elements
A method of obtaining seismic data, comprising:
- transmitting an acoustic signal into the earth;
- receiving at an acquisition unit in the field seismic signals from one or more sensors in signal communication with the earth;
- sampling the received seismic signals at the field unit into a plurality of samples;
- digitizing each sample at the data acquisition unit, each digitized samples having a same bit length;
- compressing digitized samples that meet a selected criterion;
- arranging the digitized samples into a plurality of packets, wherein at least some of the packets in the plurality of packets include compressed digitized samples;
- and
- transmitting the plurality of packets for further processing.
5 more elements
A seismic data acquisition apparatus, comprising:
- a circuit configured to receive seismic signals from a sensor and to provide a plurality of samples representative of the seismic signals, each sample having a same bit length;
- and
- a processor configured to:
- compress at least some of the samples;
- and
- arrange the plurality of samples into a plurality of packets so that at least some of the packets include one or more compressed samples.
