Introducing Signal Processing Techniques for Log-based Geomechanical Analysis

Hamed Soroush, Shell International E & P


Petrophysical logs are by far the most available data for formation evaluation in oil and gas industry. Since log measures are, to some extent, related to mechanical properties of formations, they are considered as valuable sources of information for geomechanical analysis. In this regard, analyzing log data with signal processing techniques maximizes the amount of information that can be extracted from logs. Using such techniques enables acquiring information from different frequency levels and, therefore, avoiding combined effects of different rock properties on a single data set.

This presentation aims in introducing a multi-variable workflow in order to extract geomechanical related information from logs, employing number of data processing techniques such as Bayesian, Parzen, wavelet decomposition, de-noising, and data fusion. The application of the technique in identifying borehole breakout and naturally fractured zones along the wellbore are discussed. The applicability and generalization capability of the technique are discussed using case studies on carbonate and shale gas formations
