In reflection seismology, a seismic attribute is a quantity extracted or derived from that can be analysed 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. Examples of seismic attributes can include measured time, amplitude, frequency and attenuation, in addition to combinations of these. Most seismic attributes are , but those that use , such as amplitude versus offset (AVO), must be analysed . They can be measured along a single seismic trace or across multiple traces within a defined window.

  • In reflection seismology, a seismic attribute is a quantity extracted or derived from that can be analysed 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. Examples of seismic attributes can include measured time, amplitude, frequency and attenuation, in addition to combinations of these. Most seismic attributes are , but those that use , such as amplitude versus offset (AVO), must be analysed . They can be measured along a single seismic trace or across multiple traces within a defined window. The first attributes developed were related to the 1D complex seismic trace and included: , instantaneous phase, instantaneous frequency, and . Acoustic impedance obtained from seismic inversion can also be considered an attribute and was among the first developed. Other attributes commonly used include: coherence, azimuth, dip, instantaneous amplitude, , , , AVO, and spectral decomposition. A seismic attribute that can indicate the presence or absence of hydrocarbons is known as a direct hydrocarbon indicator.
