A seismic attribute is a quantitative measure of a seismic
characteristic of interest. Analysis of attributes has
been integral to reflection seismic interpretation since the
1930s when geophysicists started to pick traveltimes to
coherent reflections on seismic field records. There are
now more than 50 distinct seismic attributes calculated
from seismic data and applied to the interpretation of geologic
structure, stratigraphy, and rock/pore fluid properties.
The evolution of seismic attributes is closely linked to advances
in computer technology. As examples, the advent
of digital recording in the 1960s produced improved measurements
of seismic amplitude and pointed out the correlation
between hydrocarbon pore fluids and strong amplitudes
