Abstract:
1. A method of transferring data during a seismic survey, from remote acquisition units to a central control unit, the method comprising: positioning an array of the remote acquisition units across a survey area, positioning plural seismic sensors across the survey area, connecting, after positioning the array of the remote acquisition units and after positioning the plural seismic sensors, one or more seismic sensors of the plural seismic sensors to corresponding remote acquisition units, performing one or more seismic events and storing resulting seismic data from the seismic sensors in the corresponding remote acquisition units, the seismic data stored by the corresponding remote acquisition units including timestamp information relating to the relevant seismic event, in which the timestamp information is derived at the remote acquisition unit from an independent remote source, wirelessly uploading data into a harvester unit by traversing the harvester unit across the survey area, the harvester unit including or being accompanied by a point-multipoint transceiver, wirelessly uploading the data from the remote acquisition units directly into the harvester unit as the harvester unit passes within range, the data passing from more than one remote acquisition unit to the harvester unit simultaneously where necessary, and wirelessly transferring the data from the harvester unit to the central control unit during the seismic survey, wherein the remote acquisition units operate in an autonomous mode while capturing, storing and forwarding the seismic data.
