General administration/exploration concession and permit work ("land and legal") topographic surveying and mapping, which is quite different for land- or marine work. For example, seismic exploration for oil and gas is a complex interaction of activities requiring good management. Various supporting field activities are required for good seismic data acquisition.

Seismic data acquisition is the gathering / recording of seismic data in the field (be it on land or at sea) with the ultimate goal to make a seismic image of the subsurface. Thus it is with seismic processing.įGDP: Fundamentals of geophysical data processing, by Jon Claerbout Then, a set of theorems is postulated and the corresponding proofs are developed. First, certain assumptions are ‘made and the necessary terms and symbols are defined. The development follows a regular procedure. Digital processing of seismic information is based on the methods and procedures of signal theory.

The full treatment and proofs may be obtained where desired from the references. In the following pages, we shall endeavour to develop an explanation of the seismic process in a straightforward manner, using simple concepts and demonstrations. However, the person who is concerned only in evaluating a given process and determining why certain results are obtained, may sidestep rigorous mathematical procedures in favour of a more pragmatic approach to the problem. The research geophysicist, the mathematician, and the computer programmer must be familiar with the theory and the proofs, in order to develop the applications and to determine their validity. As a result, there is a tremendous surge in the need to learn more about the techniques for the more efficient utilization of the seismic method. Under these conditions, management and operating personnel must appraise and evaluate the use of the new techniques. The problem is further complicated by rather complex mathematics used to derive the methods and the proofs of the operations. They must be derived from a knowledge of the processing techniques and theory, which in turn, often involve unfamiliar concepts. The reasons for this are not always apparent. Results of the processing may be often impressive, but at other times may leave much to be desired. Today, most geophysical interpretive and management personnel have had experience with digital processing of seismic data. The Nature Of Digital Seismic Processing, by Roy O.
