Evaluating the potential of carbonate sub-facies classification using NMR longitudinal over transverse relaxation time ratio [PDF]
, 2021 While the well log-based lithology classification has been extensively utilized in reservoir characterization, the classification of carbonate sub-facies remains challenging due to the subtle nuances in conventional well-logs.

International Journal of Geophysics, Volume 2015, Issue 1, 2015., 2015 A total of 13 seismic sections were used for 2D seismic interpretation in order to assess the subsurface geometry of gas sand horizons and hydrocarbon prospect of the Rashidpur structure, Surma Basin, Bangladesh. Out of five reflectors, two selected reflectors were mapped for the study.

Electro-facies classification based on core and well-log data
Journal of Petroleum Exploration and Production Technology, 2023 Facies studies represent a key element of reservoir characterization. In practice, this can be done by making use of core and petrophysical data. The high cost and difficulties of drilling and coring operations coupled with the time-intensive nature of ...

Electrofacies in Reservoir Characterization [PDF]
, 2018 Electrofacies are numerical combinations of petrophysical log responses that reflect specific physical and compositional characteristics of a rock interval; they are determined by multivariate procedures that include principal components analysis, cluster analysis, and discriminant analysis.

Supervised Machine Learning in Electrofacies Classification: A Rough Set Theory Approach
Journal of Physics: Conference Series, 2020 Abstract Electrofacies were initially introduced for defining a set of recorded log responses in order to characterize a bed and permitted it to be distinguished from the other rock units as an improvement to the traditional use of well logs.
