Elementary Theoretical Recapitulation
Published:January 01, 2011
Even though the theoretical bases that are needed to design and perform a seismic experiment (detonating a source and deploying receivers to observe the resulting motion of the ground) can be restricted to Pythagoras’ theorem and Snell's law, using the resulting data to build an image of the earth's interior requires much broader knowledge. Understanding the mathematical and physical bases of this broader knowledge is valuable for acquisition geophysicists who seek to design and perform better seismic experiments that lead to better images of the earth's interior. Those bases will be used widely throughout the remainder of this book.

Seismic Acquisition from Yesterday to Tomorrow
During the last few years, seismic acquisition has gone through a phase of fast acceleration, attested to by the development of wide-azimuth surveys, the continuous increase in channel count, and the progress in simultaneous shooting. These developments, made possible by technological advancements today, will enable the production of clearer seismic images tomorrow. Seismic Acquisition from Yesterday to Tomorrow (SEG Distinguished Instructor Series No. 14), the companion book for the 2011 SEG/EAGE Distinguished Instructor Short Course, offers a reflection on this evolution. It starts with a short historical overview, followed by discussions of signal and noise. The core of the book is the relationship between acquisition parameters and seismicimage quality. It will provide geoscientists and all those interested in seismic images with the still unconventional view of seismic data acquisition as the first component of seismic imaging.
