Short summary

CWT was applied for lithology detection over the Costa Rica margin, using gamma ray logs as a best indicator. It is observed that four major sedimentary layers terminated there with a gabbroic sill. DWT was applied on density logs to identify small changes in the rock matrix. Accordingly, wavelet-based fractal analysis was applied on every sedimentary layer. This analysis indicates that a certain portion of wells contain abundant shale and low-energy environments.
