In his classic text, Seismic Prospecting for Oil, C. Hewitt Dix remarks that the correlation of one reflection record with another, that is, the interpretation of seismic data, is a procedure that “can hardly be described in words.” First Steps in Seismic Interpretation (Geophysical Monograph Series No. 16) is a book about fundamental concepts and practices of seismic interpretation that attempts to achieve such a description. Intended for beginning interpreters, this book approaches interpretation via synthesis of concepts and practical applications rather than through formal treatment of basic physics and geology. It is based on the author’s personal experience as a seismic interpreter and is organized along the lines of notes from interpretation classes that he designs and teaches.
