It is appropriate to state a reasonable working model of the earth, and then to review briefly the state of the art in regards to anisotropy, and finally to comment upon probable future developments. The focus herein is confined to the field of hydrocarbon exploration and development, and the applications of anisotropy in this field. The scale of interest, unless otherwise specified, is the seismic scale: frequencies between 5 to 100 hz, distances on the order of 10s of meters to kms.
