REFLECTION SEISMOLOGY

DEFINITION OF SEISMIC ATTRIBUTES Schlumbeger Oilfield glossary: A measurable property of seismic data, such as amplitude, dip, frequency, phase and polarity. Attributes can be measured at one instant in time or over a time window, and may be measured on a single trace, on a set of traces or on a surface interpreted from seismic data.

DEFINITION OF SEISMIC ATTRIBUTES Wikipedia: In reflection seismology, a seismic attribute is a quantity extracted or derived from seismic data that can be analyzed in order to enhance information that might be more subtle in a traditional seismic image, leading to a better geological or geophysical interpretation of the data.

DEFINITION OF SEISMIC ATTRIBUTES Taner: Seismic Attributes are all the information obtained from seismic data, either by direct measurements or by logical or experience-based reasoning.

DEFINITION OF SEISMIC ATTRIBUTES Barnes: Seismic Attributes are tools for inferring geology from seismic reflection data. Seismic attributes aid seismic interpretation by revealing hidden features, by identifying similar patterns, and by quantifying specific properties.
