Feasibility surveys and Survey Evaluation Design (SED): – To identify the key factors that limit the seismic quality; – To classify the identified problems by order of priority and define consequently useful criteria for
the design of the land survey; – To define the acquisition parameters in function of the previously identified problems, taking into
account the processing and the reservoir solutions, as well as the survey site characteristics; – To evaluate the benefit of using new technologies such as single geophone, single vibrator and
broad-band sweeps; – To design and analyze different design templates. – To be able to carry out the acquisition with the best quality, minor environmental impact and best

UNITE can work with an external 40Ah lithium battery to extend its cycle life. – 40Ah lithium battery can power a RAU for ~480 hours – Once the external battery hits 11V, the RAU will switch to its internal battery for another ~158 hours
Higher flexibility Portable Field Terminal (PFT) and Data Harvester (DH)
Jornada sobre recursos no convencionales - 26 de mayo de 2014 - Eric GILLOT
Serial number assignment to peg numbers: PFT Used by line crew match the RAU serial number with the line and station numbers The PFT has a RFID scanner that is used to record the RAUs serial number As you scan the RAU it will save a file with the serial number, the line, and the station.
QC with DH – Each station laid is QC’ed – During this process the headman will check the following:
– GPS status – Battery status – Sensor test – Instrument test – Wifi RSSI

QC effort is linked to the operating risk to lose data RAU EX : three ways to collect seismic data and/or QC attributes:
In real time through wireless connection from the recorder (1)
Harvesting teams in the field with data harvester: (2) Walking or UTV crews teams harvesting QC and seismic data simultaneously
Harvesting at the staging camp: : (3) After RAUs have been picked up, data is retrieved with data harvesters. The harvesters are then brought to the recorder and downloaded to the eUnite server.
Even after harvesting data is never erased (cycling buffer memory). With a 16 Gb RAU you can record 480 hours at 2ms SR (with compression)
Higher flexibility Harvesting QC attributes and/or seismic data
Jornada sobre recursos no convencionales - 26 de mayo de 2014 - Eric GILLOT
Real time monitoring for both data and attributes :
1000m range (line of sight) from recording truck location CAN (Cell Access Node) is connected directly to eUnite system Observer can run ambient noise test for RAU’s in communication range
QC attributes are checked immediately at recorder
Higher flexibility Real time harvesting through wireless connection from the recorder (1)

Wireless harvesting Once the trace is picked up, the RAU is transferred close to the recorder location or at staging. Then RAU’s are laid by group of 100 and the data will be harvested using a Data Harvester.

RAU EX was utilized in S4 due to a challenging terrain and a shallow target: – Intense agriculture, with a considerable number of villages and lakes – A major advantage of Unite over “blind-shooting” systems is the ability to collect the
seismic data at any time, even while still recording
