Seismic reflection surveys are used extensively in exploration for oil and gas, coal and other mining, and the study of the Earth's deep crustal layers. The success of the technique for oil and gas exploration in both land and marine areas has led to continued advances in technology for gathering, processing, and interpreting the data. In fact, successful exploration requires integration of information from several disciplines, and it is seismic interpretation which brings them together. The interpretation workflow addresses structure, stratigraphy and sedimentation, seismic amplitude analysis, and assimilation of seismic attributes, rock physics analysis and visualization, all supported by relevant data from drilling, laboratory studies, and from other surveys such as aeromagnetic, gravity, and electromagnetic. Needless to say, good geological knowledge of any area of interest is required to realize the potential of the seismic reflection technique and to complete a thorough and consistent interpretation.
