Item Fuzzy clustering algorithm for Lithofacies classification of Ordovician unconventional Tight-sand reservoir from well-logs data (Algerian Sahara)(2019) Cherana, Amina; Aliouane, Leila; Doghmane, Mohamed Zinelabidine; Ouadfeul, Sid-AliIn this paper we present an approach based on a fuzzy clustering algorithm applied for lithofacies classification in an unconventional tight-sand reservoir from well-logs data. In some cases, these kinds of reservoirs are ra-dioactive due to the presence of non clayey radioactive minerals. However, conventional methods can give bad results. For that, artificial intelligence such as Fuzzy logic, can be suitable to solve the problem. Fuzzy clustering is an unsupervised machine learning technique where a given set of data is classified into groups. Hence, fuzzy logic is a more general logic then classical logic because it does not ignore uncertainties and accepts the implicit consideration of the inherited error associated with any physical measurement. This techniquet has been applied to real data of one well in an unconventional tight-sand reservoir in the Algerian Sahara. Predicted results are compared to lithofacies obtained from conventional methods and spectral mineralogical well-logs data Keywords: Well-log, Unconventional Tight reservoir, Lithofacies, Fuzzy logic, ClusteringItem Ionospheric data prediction of DEMETER Satellite using Levenberg Marquardt neural network model. application to ISL instrument(2015) Ouadfeul, Sid-Ali; Tourtchine, Victor; Aliouane, LeilaItem Structural edges delimitation from gravity data using the wavelet transform(2013) Ouadfeul, Sid-Ali; Aliouane, LeilaItem Lithofacies classification using the multilayer perceptron and the Self-organizing neural networks(Springer, 2012) Ouadfeul, Sid-Ali; Aliouane, LeilaItem Lithofacies classification using the multilayer perceptron and the Self-organizing neural networks(Springer, 2012) Ouadfeul, Sid-Ali; Aliouane, LeilaItem Total organic carbon prediction in shale gas reservoirs using the radial basis function neural network(2015) Ouadfeul, Sid-Ali; Aliouane, LeilaItem Identification and evolution of clay minerals in the sand-shale reservoirs of the Berkine basin (Algeria)(HAL, 2010) Boudella, Amar; Aliouane, Leila; Bounif, Abdallah; Benaïssa, Zahia; Benaissa, Abdelkader; Bentellis, Abdelhakim; Aïfa, TaharItem Solar geomagnetic activity prediction using the fractal analysis and neural network(2010) Ouadfeul, Sid-Ali; Aliouane, LeilaItem Aeoromagnetic data analysis using the 2D continuous wavelet transform(2011) Aliouane, Leila; Ouadfeul, Sid-Ali; Boudella, AmarItem Heterogeneities analysis using the generalized fractal dimension and continuous wavelet transform(2012) Ouadfeul, Sid-Ali; Aliouane, Leila; Boudella, Amar
