A Review of Reservoir Rock Typing Methods in Carbonate Reservoirs: Relation between Geological, Seismic, and Reservoir Rock Types [PDF]
Iranian Journal of Oil & Gas Science and Technology, 2018 Carbonate reservoirs rock typing plays a pivotal role in the construction of reservoir static models and volumetric calculations. The procedure for rock type determination starts with the determination of depositional and diagenetic rock types through ...

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.

Effect of the thermal gradient variation through geological time on basin modeling; a case study: The Paris basin. [PDF]
, 2005 Many studies investigated the thermal modeling of the Paris basin for petroleum interests during the 1970s. Most of the softwares developed by oil companies or research centers were based on the assumption of a constant thermal gradient. In order to take
