Electrofacies characterization using multivariate statistical tools [PDF]

open access: yes, 2015
This paper presents a method for electrofacies characterization which is based upon multivariate statistics analysis applied to well log data obtained from lithological classes identified in the core samples of oil and gas wells.

STANDARDIZATION OF NMR T2 CUT OFF AND BETTER ELECTROFACIES MODELLING OF LOW RESISTIVITY CARBONATES WITH MULTI POROSITY SYSTEM

open access: yes, 2021
Petrophysical evaluation and proper interpretation of carbonate reservoir is always a challenging task. The difficulty increases as the inherent heterogeneity increases in the reservoir due to its lithology, mineralogy, pore structure, pore distribution,

Electrofacies Characterization in Lacustrine Coquinas and Hybrid Deposits from Rift Phase: Pre-Salt, lower Cretaceous, Campos Basin, Brazil [PDF]

open access: yes, 2019
This study presents electrofacies models for two wells with cores and sidewall cores of Coqueiros Formation, lower Cretaceous of Campos Basin. The WELL-1 is located in deep water of the south of the basin and is composed by bioclastic carbonate ...

Committee Machine Learning for Electrofacies-Guided Well Placement and Oil Recovery Optimization

open access: yes
Electrofacies are log-related signatures that reflect specific physical and compositional characteristics of rock units. The concept was developed to encapsulate a collection of recorded well-log responses, enabling the characterization and ...

ELECTROFACIES CHARACTERIZATION USING SELF-ORGANIZING MAPS

open access: yes, 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.

Automated feature classification and knowledge extraction from wireline geophysical observations: big data potential for offshore resources assessment

open access: yes, 2018
Scientific drilling of the volcanic ocean crust recovers cores and undertakes downholewireline logging. However, because core recovery rates are typically low (<30%), interpreting thewireline data is essential to gain a complete understanding of the ...
