since the use of interval analysis is inevitable because of uncertainty, where are you going to start applying the method or analysis of intervals to create fragility curves?
Dear Michael Bautista Baylon:
If what you are trying to do is to derive or estimate fragility (brittleness) from well profiles to match with seismic data, it is necessary:
1) that the selected well-logs have a full-wave sonic dataset, it means: P and S velocity and density in the area of interest. From Vp, Vs and density, you can estimate the elastic parameters of Young and Poisson's ratio, and then the brittleness.
2) you need a prestack simultaneous inversion seismic dataset. It means: the P-impedance, S-impedance and density seismic volumes.
From 1) you get a possible scenario of the brittleness of the reservoir rocks in you zone of interest, to match with 2).
Let me illustrate with an example of a case study of Argentina.
I hope the answer can help to you. Best wishes Sir.
Mario
