Seismic methods for imaging physical properties of the Earth

We present an integrated study in which we develop a range of techniques for deriving images of rock properties, such as porosity and shaliness, from cross-well seismic tomograms. One of the keys is to incorporate rock physics knowledge of the relations between velocity, porosity, and clay content which were developed in the laboratory and calibrated in the field. Geostatistical techniques, such as kriging and cokriging, are used as a means to combine the heterogeneous data set, consisting of well logs, the tomogram, and laboratory results
