Equipment tests,To ensure that seismic data are produced and recorded correctly to the specifications provided in the contract, it is essential that all items of equipment associated with the data acquisition are working properly. To this end, they must be tested regularly. The birddog must make sure that this is done.

Topographical survey,The topographical survey is an essential part of the whole seismic operation. Even if the birddog does not have personal experience of working as a surveyor, the work of this department can be supervised without difficulty as its products are visible and calculable.

Permitting,Permitting for the operation of a seismic crew is not part of the data quality control function of the birddog, but it can have great influence on the rate of production of the crew and the final cost of the survey to the client. It is an important part of the birddog’s overall responsibility for the operation of the crew.

Exploration, project. As the predominant, world-wide, commercial activity that uses geophysical techniques, in particular the seismic method, is the search for reservoirs of oil and gas, this will be used as the example. Other activities must necessarily follow a similar pattern.
