<div>Bright spot analysis is generally used in exploration for hydrocarbons, especially in the Search for gas. However, many seismic amplitude anomalies have not been caused by gas accumulations, but they</div><div>are related to lithological changes. AVO methods (amplitude vs. offset</div><div>methods) can be used to distinguish between the presence of gas and lithological changes.</div><div>The Grubišno polje field has been defined and mapped by these methods,and a well drilled afterward confirmed the results. After</div><div>acquiring the well-logging data a Synthetic was computed. The correlation of the Synthetic with the reprocessed seismic sections and the AVO data enabled the more precise vertical and horizontal definition of the gas accumulation. This method and results contribute to the more rational exploration and developmenl of a gas field.</div>
