Multiattribute seismic analysis is a broad term that encompasses all geostatistical methods that utilize more than one attribute to predict some physical property of the earth. Bivariate geostatistics is obviously the simplest subset of the multivariate techniques and thus the standard technique of cokriging could be called multivariate geostatistics. However, in this paper we will use the name to refer to geostatistical methods that use more than two variables. Even then, there are many different methods that fall under this heading. There are three major subcategories.
