Birddog: Philosophy and practice of seismic data quality by John Scott Roy (auth.)

By John Scott Roy (auth.)

This ebook describes the equipment and attributes required for the compe­ tent qc of the knowledge acquisition of a seismic exploration team working on land. even supposing the booklet is worried typically with explo­ ration for oil and fuel reservoirs, and all of the subject matters which are mentioned in it are focused on that focus on, the cloth is acceptable to different components of seismic exploration resembling civil engineering and the quest for different minerals. The publication contains the distillation of greater than thirty years' adventure in geophysical exploration in all its points and in lots of components of the area. Seismic information acquisition caliber supervision is one point of geophysical exploration which, even supposing of significant significance, has had, as far as the author knows, no textbook dedicated to it. it really is was hoping that it'll be of curiosity to an individual who's engaged, in no matter what capability, in geophysical exploration and should support them to realize their aim, that's illustrated in Fig. 1. 1. The time period birddog is colloquial within the geophysical exploration undefined. it's a handy shorthand identify to explain the individual whose complete name is, and who acts as, the information acquisition qc manager on a box seismic exploration workforce. The time period is used additionally to explain the individual that is the client's consultant at the box workforce. In perform an analogous individual plays either capabilities on behalf of the client.

Example text

12 shows the sequence of events which takes place in order that the energy stored in the source is released and input to the ground as a seismic signal. e. explosives and vibrators. Many types of source have been used in the history of seismic exploration. Explosives of various kinds are still a common source of energy. A longer discussion about them occurs later, in Chapter 19. The danger in handling explosives and other difficulties associated with them encouraged the development of non-explosive surface sources.

Each item is capable of being broken down into essential and support subsystems. As far as possible, the descriptions of the items, given below, will be of a generic nature. For example, no attempt will be made to describe specific recording instruments.
