Abstract

Seismic data is extremely beneficial to envisage the subsurface lithologies. However, only seismic data is not sufficient to stipulate the gas reservoir. In this paper, by reviewing many signposts in the development of AVO methodology regarding the principles of AVO analysis, we applied AVO analysis to two formations (Murree and Sakesar). We have endeavored to cover the critical formulae and the most current tools in AVO analysis. After comparing multiple methods, we determined that the Aki and Richards equation is the best technique for the AVO analysis in this area because it provides the most accurate results. Because the Aki and Richards approximation is deviates at all angles, it will show the deviation when the angle is either small or large. Here deviation means that the curve plotted are matching to the Zoeppritz curve or not.
