| Abstract | |
The study of the reflection coefficients, their approximations and the AVO (Amplitude Variation with Offset) analysis plays an important role in the oil industry as they can help to describe the interest region lithology. The first part of this work deals with the main ideas of the deduction of the reflection coefficients PP (P incident and P reflected waves) and PS (P incident and S reflected waves). Then, different approximations for these equations are presented, followed by a discussion of their behavior when compared among them and with their exact expressions. We introduce a new approximation for the reflection coefficient PS similar to the reflection impedance of PP coefficient proposed recently. To conclude, some indicators and their accuracy are discussed and a brief summary about the traditional AVO analysis is presented. (AU) | |
