Resumen:

AVO analysis for converted waves has been restricted to modeling of the AVO responses as -a function of the off-set varying some horizon characteristics, such as thickness and Vp/Vs ratio. To generalize, facilitate, and make comparable to the the P-wave AVO analysis the converted wave reflection coefficient Rps(O) given by Ak and Richards (1980) has been simplified to a linear expression. This approach will provide two seismic sections: (1) a rigidity relative contrast and (2) a pseudo Vp/Vs ratio. These two sections could be potentially used to discriminate and recognize possible gas/oil zones in conjunction with the P-wave AVO analysis outputs.
