Integrated Lithofacies and Petrophysical Properties Simulation

SPE Western Regional Meeting, 1997
Abstract This paper presents a new procedure that simultaneously generates consistent distributions of categorical lithofacies and continuous petrophysical properties, i.e., porosity and permeability. The technique used is the conditional simulation method which is capable of honoring the original distribution of ...

Lithofacies Palaeogeography Reconstruction Based on GIS

Applied Mechanics and Materials, 2012
The facies palaeogeographic reconstruction can be achieved by using the single factor analysis and multi-factor comprehensive mapping method and GIS spatial analysis functions. Single factors are the factors which can independently reflect some characteristics of sedimentary environments of a stratigraphic interval of a section in an area, such as the ...

Carbonate lithofacies as paleolatitude indicators: problems and limitations

Sedimentary Geology, 1988
Abstract Detailed study of Miocene carbonates in the Mediterranean region and their analogues on modern carbonate shelves (in the Mediterranean Sea, Brazil and other areas) reveals at least three major types of carbonate platform lithofacies in addition to the classic tropical coral reef (chlorozoan) lithofacies: (a) chloralgal lithofacies, similar ...

Lithofacies Recognition Based on Extreme Learning Machine

Applied Mechanics and Materials, 2012
To overcome the problem of lower training speed and difficulty parameter selection in traditional support vector machine (SVM), a method based on extreme learning machine (ELM) for lithofacies recognition is presented in this paper. ELM is a new learning algorithm with single-hidden layer feedforward neural networks (SLFNN).

Characteristics and Evolution of Lithofacies Paleogeography

2020
Similarities in global tectonics evolution and the unity of global sea level eustasy in the Paleozoic have provided a scientific foundation for sequence stratigraphy research. Since its development in 1987–1988, sequence stratigraphy has been applied in geological research worldwide with astonishing speed and breadth.

Carboniferous lithofacies, Halkyn Mountain, North Wales

Geological Journal, 1969
AbstractA brief description of the carboniferous succession on Halkyn Mountain, North Wales, together with a map illustrating the areal distribution of upper Viséan carbonate and Namurian non‐carbonate lithologies, is presented. The upper Vistan carbonates have been divided into four major units termed in ascending order: A1 (pelsparites and ...

Petrophysical Rocks: Electrofacies and Lithofacies

2014
Many years ago, the classification of sedimentary rocks was largely descriptive and relied primarily on petrographic methods for composition and granulometry for particle size. The compositional aspect broadly matches the goals of the previous chapter in estimating mineral content from petrophysical logs.

LITHOFACIES PROPERTIES OF ANTALYA TUFAS

2004
The tufa term is described as secondary calcium carbonate deposits which are deposited by biologicand/ or physicochemical processes under cool water conditions and contain macro and micro scales plant, animal remains and bacteria ( especially cyanobacteria ). Tufas have especially deposited at Quaternary and recenttime.

Lithofacies of Pella Formation (Mississippian), Southeastern Iowa

AAPG Bulletin, 1969
The late Valmeyeran Pella beds of southeastern Iowa are elevated formally to the rank of formation. A type section and several reference sections are designated. The Pella Formation consists of a distinctive series of carbonate strata containing seven lithofacies representing fluctuations in environment near mean sea level within the Genevievian Sea ...
