A method of analyzing a 3D geological structure using a structure index. The method includes the steps of estimating physical property values on common coordinates to calculate two or more physical property models on the same 3D grid (L&#xd7;M&#xd7;N); normalizing the physical property models, thus obtaining normalized physical property models which are then represented in a scatter plot of physical properties; converting distribution positions of the normalized physical property models on the scatter plot of physical properties into type angle (TA) and into type intensity (TI); determining a minimum of TI values, which classifies two or more classes on a scatter plot of the TA and TI values, to be a threshold; and analyzing the 3D geological structure based on a local extreme point and/or points in the scatter plot for the TA and TI using the threshold.
