Automatic lithofacies segmentation using the Wavelet Transform Modulus Maxima lines WTMM combined with the Detrneded Fluctuation Analysis DFA

The main goal of this paper is to establish an algorithm of segmentation of lithologies based on welllogs<br>data processing by the wavelet transform modulus maxima lines (WTMM).Combined with the detrneded<br>fluctuation analysis DFA .To automate interpretation and to help the geologists to construct the lithofacies. A study<br>made by B.Audit and al showed that this estimator is recommended for signal of low number of samples , we<br>used it to enhance the estimation of the coefficients of roughness of the various geological mediums.
