Method and system for transmission of seismic data
DCFirst Claim
1. A method of seismic data acquisition comprising:
- providing a plurality of seismic data acquisition units, each unit comprising a transceiver configured to wirelessly communicate seismic data with one or more of the other seismic data acquisition units in the plurality of seismic data acquisition units;
providing a one or more concentrator units each comprising a receiver configured to wirelessly receive seismic data from at least one of the seismic data acquisition units; and
wirelessly communicating acquired data from the acquisition units to the concentrator units;
wherein the step of wirelessly communicating acquired data from the acquisition units to the concentrator unit comprises using a string of the seismic data acquisitions units to wirelessly communicate acquired seismic data; and
wherein, during the step of wirelessly communicating acquired data from the acquisition units to the concentrator units, a first pair of acquisition units communicate with each other at the same time that a second pair of acquisition units communicate with each other; and
further comprising;
assigning first and second transmission parameters to the first and second pairs of acquisition units to substantially prevent communication interference between the first and second pairs.

Abstract
The transmission method utilizes multiple seismic acquisition units within an array as intermediate short range radio receivers/transmitters to pass collected seismic data in relay fashion back to a control station. Any one seismic unit in the array is capable of transmitting radio signals to several other seismic units positioned within radio range of the transmitting unit, thus allowing the system to select an optimal transmission path. Utilizing an array of seismic units permits transmission routes back to a control station to be varied as needed. In transmissions from the most remote seismic unit to the control station, each unit within a string receives seismic data from other units and transmits the received seismic data along with the receiving unit'"'"'s locally stored seismic data. Preferably, as a transmission is passed along a chain, it is bounced between seismic units so as to be relayed by each unit in the array.
