Method of joint analysis and interpretation of the subsurface from multiple seismic derived layer property data sets

A method for classification of a subsurface, comprising the steps of:

• a) inputting at least two seismic derived layer property data sets, each data set being of a certain data type, for classification of the subsurface;
• b) inputting data defining one or more zones of interest in the classification input data sets;
• c) inputting analysis data sets with data types corresponding to that of the classification input data sets, the analysis data sets being calibrated to the classification input data and the analysis data sets defining a data type space;
• d) inputting data defining a subset of interest in the analysis data sets;
• e) defining in the subset of interest within the data type space one or more data type subspaces that individually or in combination characterize one or more subsurface features;
• f) selecting at least one data type subspace to be used for classification;
• g) determining which data points of the classification input data in the zone of interest fall within said selected data type subspace or data type subspaces;
• and
• h) typifying these data points of the classification input data to so classify these data points of the classification input data.
