摘要
A method and apparatus for identifying non-elastic indicators for a subsurface region, the method including obtaining seismic data for the subsurface region; generating a best-fit elastic model from the seismic data; and identifying non-elastic indicators from the seismic data and the best-fit elastic model. The method and apparatus may also include estimating reservoir flow properties from the non-elastic indicators based on a poroelastic interpretation of the seismic response. The method and apparatus may also include subdividing the seismic data into a plurality of subdivisions, wherein: generating the best-fit elastic model from the seismic data includes generating an individual best-fit elastic model for each subdivision; identifying non-elastic indicators from the seismic data and the best-fit elastic model includes identifying individual non-elastic indicators from each subdivision and its respective individual best-fit elastic model; and estimating the reservoir flow properties from the non-elastic indicators comprises analyzing the individual non-elastic indicators based on the subdivisions.
