Abstract

A method, apparatus and system for acquiring seismic data is disclosed that in one aspect receives a seismic signal detected by at least one sensor in response to a seismic energy signal generated by a source at a selected location at a data acquisition unit in data that is in data communication with the sensor, receives at least one parameter of the source and/or receiver at the data acquisition unit; and generates a data block at the data acquisition unit having data representative of the received seismic signal and a header that contains data representative of the at least one parameter of the source and/or receiver. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

Claims

1. A method of acquiring seismic data, comprising:

using a portable tool to record at least one source parameter relating to a source configured to generate a seismic energy signal;

transmitting the at least one source parameter to a central station computer;

receiving at a data acquisition unit, after the data acquisition unit has been positioned, the at least one source parameter;

receiving at the data acquisition unit a seismic signal detected by at least one sensor in response to a seismic energy signal generated by the source at a selected source location, the data acquisition unit being in data communication with the at least one sensor;

generating a data block at the data acquisition unit having data representative of the received seismic signal and a header that contains data representative of the at least one source parameter; and

storing the generated data block on a storage medium.

2. The method of claim 1, wherein the at least one source parameter is selected from a group consisting of:

(i) an x-coordinate of the selected source location;

(ii) a y-coordinate of the selected source location;

(iii) an elevation of the selected source;

(iv) a source identification;

(v) a depth of the source relative to a datum;

(vi) a size of a source charge;

(vii) an uphole time corresponding to the selected location;

(viii) a frequency of a vibrator source;

(ix) an amplitude of a vibrator source;

(x) a sweep length of a vibrator source;

(xi) a number of sweeps made by a vibrator source;

(xii) a sweep taper for a vibrator source;

(xiii) a shape of a sweep of a vibrator source; and

(xiv) a source type.

3. The method of claim 1, wherein receiving the at least one source parameter comprises receiving the at least one source parameter from a remote unit that is one of:

(i) a central system computer in data communication with the data acquisition unit and (ii) a portable unit in data communication with the data acquisition unit.

4. The method of claim 1, further comprising:

transferring the data block from the data acquisition unit to one of;

(i) a remote unit that wirelessly receives data blocks from a plurality of data acquisition units and (ii) a portable device that downloads the data block from the data acquisition unit.

5. The method of claim 1, further comprising:

receiving at least one parameter of the at least one sensor at the data acquisition unit and integrating the at least one sensor parameter in the header.

6. The method of claim 5, further comprising:

integrating the at least one sensor parameter and the at least one source parameter to generate the data block that is substantially process ready for providing a seismic map of an earth subsurface.

7. A non-transitory computer-readable medium product having a program thereon that, when executed, cause at least one processor to execute a method, the method comprising:

recording at least one source parameter relating to a source configured to generate a seismic energy signal that was obtained by a portable tool;

transmitting the at least one source parameter to a central station computer;

receiving at the data acquisition unit, after the data acquisition unit has been positioned, at least one source parameter from a source configured to generate a seismic energy signal;

receiving at a data acquisition unit a seismic signal detected by at least one sensor in response to a seismic energy signal generated by the source at a selected source location, the data acquisition unit being in data communication with the at least one sensor;

generating a data block at the data acquisition unit having data representative of the received seismic signal and a header that contains data representative of the at least one source parameter; and

storing the generated data block on a storage medium.

8. The non-transitory computer-readable medium product of claim 7, further comprising at least one of:

(i) a read-only memory (ROM), (ii) a programmable read-only memory (PROM), (iii) an electrically programmable read-only memory (EPROM), (iv) an electrically alterable read-only memory (EAROM), (v) an electrically erasable and programmable read-only memory (EEPROM), (vi) a flash memory, (vii) an optical disk, (viii) a hard drive, and (ix) a non-volatile read-write memory (NOVRAM).
