Resumen:

We present in this paper a method to summarize information contained in seismic attribute maps that consists of comparing the attribute response around calibration points in a given reservoir with the attribute response in the rest of the field. The method has three stages. In the first one, the calibration points are selected and classified into different categories. In the second one, similarity maps related to each category are created. The similarit maps show variations of a single primary color which is different for each category of control points. High values in these maps represent areas whose attribute response is close or equal to the attribute response around the calibration points. Low values indicate areas whose attribute response has little or nothing in common with the response around the calibration points. In the third stage, similarity maps are combined into a single map whose different color saturation indicate the resemblance according to each category. Colors in this final map result from combining primary colors of the individual similarity maps. The basic idea to interpret these maps is that areas with similar seismic response, and close to the control points, should have similar rock properties, assuming changes in the reservoir are gradual.
