Introduction,ing on land. Although the book is concerned mainly with exploration for oil and gas reservoirs, and all the topics that are discussed in it are centred on that target, the material is applicable to other areas of seismic exploration such as civil engineering and the search for other minerals. The bo

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.

阴谋

Seismic data quality control,e 6.1 shows a synthetic seismic record in which the various modes of seismic wave propagation appear. It tries to portray, clearly, the desirable and the undesirable events that can be recorded from a single shot. Of course, it bears little relation to the reality of most seismic records obtained du

BRACE

Field parameters,ent are correct the birddog usually can assume that they will remain constant for the rest of the day, unless some extra tests have been made. However, as was mentioned in the previous chapter, some flexible parameters need to be watched.

Unless the client is willing to spend huge amounts of money on transporting everything by helicopter or to abandon the project, it is necessary to cut tracks for the vehicles, both on the seismic line and for access to the line.
