Seismic acquisition system
First Claim
1. A seismic survey system, comprising:
- a plurality of transmitters;
a plurality of data sources positioned about an area to be surveyed, each data source, when in operation, communicating with one of the transmitters that, when in operation, transmits data from the data sources;
a plurality of cells each containing a portion of the data sources and the transmitters with which they communicate, one of the transmitters within each cell also serving as a gateway during operation for receiving data transmitted from the other data source transmitters within the cell and transmitting the data collected within the cell; and
a plurality of independent pathways, each independent pathway containing a least one gateway through which data is transmitted during operation along each pathway via at least one gateway in that pathway without consolidation of data.

Abstract
An apparatus and method for collecting data acquired during a seismic survey are disclosed. The apparatus is a seismic survey system, comprising a plurality of data sources, a plurality of cells, and a plurality of independent pathways. The data sources are positioned about an area to be surveyed, each data source being associated with a transmitter capable of transmitting data. The cells each contain a portion of the data sources and their associated transmitters. One of the transmitters within each cell also serves as a gateway for receiving data transmitted from the other data source transmitters within the cell. The independent pathways each contain a portion of the gateways whereby data may be transmitted along each pathway via the gateways and associated transmitters in that pathway. The method is a method for conducting a seismic survey. The method comprises positioning a plurality of seismic data sources about an area to be surveyed; defining a plurality of cells such that each cell contains a portion of the seismic data sources; defining one of the seismic data sources within each cell to also serve as a gateway; defining a plurality of independent pathways such that each pathway contains a portion of the gateways; within each respective cell, transmitting seismic data from the seismic data sources to the gateway; and, within each pathway, transmitting the seismic data from one gateway to another to reach a central location.

18. A method for use in seismic surveying, comprising:
-
collecting a plurality of seismic data at a plurality of seismic data sources, each data sources communicating with a transmitter that, in operation, transmits data, the seismic data sources being organized into a plurality of cells, one of the transmitters within each cell also serving as a gateway for receiving data transmitted from the other data source transmitters within the cell; transmitting the collected seismic data over a plurality of independent pathways to a central location, each independent pathway containing at least one gateway through which data is transmitted during operation along each pathway via the at least one gateway without consolidation of data; and collecting the transmitted seismic data at the central location. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
