A good understanding of the effect of rock and pore-fluid properties
on seismic waves is necessary for the characterization of a subsurface
hydrocarbon reservoir from a seismic data set. Information about
the rock and fluids in the reservoir can be obtained, for example,
through well logging and laboratory tests with samples cored from
the wellbore. Together with seismic data, this information can be
extrapolated for the entire dimension of the reservoir to provide
valuable quantitative estimates for production. Additionally, this
information can be extrapolated in time for monitoring the spatial
redistribution of fluids during production. Making such space and
time extrapolations more accurate using seismic data is the main
goal of rock physics. For that, identifying and understanding the
physical processes taking place in a reservoir rock at different
scales is an important step and the subject of our article.
