Fernández Ciencias de la Tierra Facies model Mathematical models Facies reconstruction Sedimentary heterogeneity The geological community is increasingly aware of the importance of geological heterogeneity for managing subsurfaceactivities. In sedimentary bodies, facies distribution is an important factor constraining geological heterogeneity.Statistical grid-based sedimentary facies reconstruction and modelling methods (FRM methods) can be used to provideaccurate representations (reconstructions or models) of facies distribution at a variety of scales, which can beconditioned to hard and soft data. These representations enable geological heterogeneity to be quantified; and therefore,serve as important inputs to manage projects involving subsurface activities. FRM methods are part of a generalworkflow comprising the construction of a surface-based framework, which is used to build the modelling grid inwhich these methods operate. This paper describes this workflow and provides an overview, classification, descriptionand illustration of the most widely used FRM methods (deterministic and stochastic). Among others, two selecteddatasets comprising alluvial-palustrine and turbiditic deposits are used for illustration purposes. This exercise enablescritical issues when using FRM methods to be highlighted and also provides some recommendations on theircapabilities. For deterministic facies reconstruction, the main choice of the method to be used is between that employinga continuous or a categorical method. For stochastic facies modelling, choosing between the different techniquesmust be based on the scale of the problem, the type and density of available data, the objective of the model, and theconceptual depositional model to be reproduced. Realistic representations of facies distribution can be obtained if theavailable methods are applied appropriately 2007 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50550301 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.3 Vol.5 |
