Development and Validation of a Novel Interpretation Algorithm for Enhanced Resolution of Well Logging Signals

Journal of Sensors, Volume 2021, Issue 1, 2021., 2021
This work presents a novel algorithm that achieves enhanced resolution of well logging signals, e.g., from 1 ft of a pulsed neutron mineralogy tool to 0.04 ft of an imaging tool. The algorithm, denoted as “Digital Core,” combines mineralogical and sedimentological information to generate a high‐resolution record of the formation mineralogy which can be

K-Mean Clustering Analysis and Logistic Boosting Regression for Rock Facies Characterization and Classification in Zubair Reservoir in Luhais Oil Field, Southern Iraq

Iraqi Geological Journal, 2021
Identifying rock facies from petrophysical logs is a crucial step in the evaluation and characterization of hydrocarbon reservoirs. The rock facies can be obtained either from core analysis (lithofacies) or from well logging data (electrofacies). In this

ELECTROFACIES CHARACTERIZATION USING SELF-ORGANIZING MAPS

Revista Brasileira de Geofísica, 2012
The characterization of electrofacies is essential for reservoir modeling. However, this is a process that dependends on many variables, with errors and associated noise that interfere on visual interpretation. In order to minimize uncertainties, this paper proposes the use of the artificial neural network called Auto-Maps Organizing, which is a ...
