Facies and facies models - Geological Digressions
网页2020年8月18日 · The Geological Association of Canada (now Geoscience Canada) in 1976 introduced the iconic series Facies Models, edited by Roger Walker. This set of papers, perhaps more than any others, brought facies models into the mindful living rooms of students of sedimentology and stratigraphy.
Facies models - SpringerLink
网页Facies classifications were initially mainly descriptive, based on observable, measurable features such as the composition and texture of sedimentary rocks. As time went by, facies models were developed based on the inferred process of formation. Such genetic facies models generally have the suffix “-ite”, e.g., “turbidite”.
Facies Models - SpringerLink
网页Facies models, or “summaries of the environment” (Sect. 3.4.2), are essential mental constructs that stratigraphers must build as they develop sequence-stratigraphic and chronostratigraphic interpretations of their subject rocks. This chapter is designed to provide a flavor of the type of work that needs to be done.
Facies Analysis - SpringerLink
网页A facies model is an interpretive device, which is erected by a geologist to explain the observed facies association. A facies model may be developed at first to explain only a single stratigraphic unit, and similar units may then be …
Facies Model - Reservoir modelling: A practical guide - Wiley …
网页The objective of the facies model is to incorporate the medium-scale reservoir heterogeneity represented by the sedimentary geology into the architecture of the geocellular grid. Using a stochastic process to populate the facies model allows the modeller to test the predicted proportion and distribution of any facies.
Eolian Facies Models | Facies Models Revisited - GeoScienceWorld
网页2006年1月1日 · The development of eolian facies models is important for understanding the likely response of desert systems to climatic and environmental change. Additionally, predictive models remain important for hydrocarbon exploration, particularly in mature provinces, where good well control allows the employment …
Towards a robust parameterization for conditioning facies models …
网页2019年7月1日 · Highlights. •. Novel parameterization for facies history matching combining deep learning and ensemble smoother. •. Use of a convolutional variation autoencoder to map discrete facies values into continuous parameters. •. Assimilation of static and dynamic (production) data using the method ensemble …
Multi-condition controlled sedimentary facies modeling based on ...
网页Canchumuni et al. (2021) try different GAN models to build a continuous parameterization of the facies model, and the conditioning of the generator is done during the inversion process. Razak and Jafarpour (2022) report two implicit learning-based methods to condition the generated complex geological models.
Facies Models Revisited - GeoScienceWorld
网页2006年1月1日 · Recent development of fluvial facies models has been due to improved description of natural river and floodplain processes and deposits using: (1) ground-penetrating radar (GPR) combined with cores and trenches to describe modern deposits in 3D; (2) study of frozen rivers to allow easy access to the entire channel belt and procurement of ...
