Web8 uur geleden · Lithofacies were divided into 12 types, based on rock type, sedimentary structure, and other related factors. The sedimentary environment was determined by analyzing the color of the mudstone. The sandstone bodies were divided vertically, based on lithology changes, the location of mudstone deposits, and scouring structures. Web1 jul. 2001 · We present a methodology for estimating uncertainties and mapping probabilities of occurrence of different lithofacies and pore fluids from seismic amplitudes, and apply it to a North Sea turbidite… Expand 103 Near and far offset impedances: Seismic attributes for identifying lithofacies and pore fluids T. Mukerji, A. Jørstad, G. Mavko, J. …

Lithofacies vs Facies - What
Lithology is the basis of subdividing rock sequences into individual lithostratigraphic units for the purposes of mapping and correlation between areas. In certain applications, such as site investigations, lithology is described using a standard terminology such as in the European geotechnical … Meer weergeven The lithology of a rock unit is a description of its physical characteristics visible at outcrop, in hand or core samples, or with low magnification microscopy. Physical characteristics include colour, texture, grain size, … Meer weergeven In igneous and metamorphic rocks, grain size is a measure of the sizes of the crystals in the rock. In igneous rock, this is used to determine the rate at which the material cooled: large crystals typically indicate intrusive igneous rock, while small crystals … Meer weergeven The fabric of a rock describes the spatial and geometric configuration of all the elements that make it up. In sedimentary rocks the … Meer weergeven The texture of a rock describes the relationship between the individual grains or clasts that make up the rock. Sedimentary textures include the degree of Meer weergeven The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic. Igneous rocks are formed directly from magma, which is a mixture of molten rock, dissolved gases, and solid crystals. Sedimentary … Meer weergeven In rocks in which mineral grains are large enough to be identified using a hand lens, the visible mineralogy is included as part of the description. In the case of sequences possibly … Meer weergeven The colour of a rock or its component parts is a distinctive characteristic of some rocks and is always recorded, sometimes against standard colour charts, such as that produced by the Rock-Color Chart Committee of the Geological Society of America based … Meer weergeven WebABSTRACT Lithology identification is of great importance in reservoir characterization. Recently, many researchers have applied machine-learning techniques to solve lithology identification problems from well-log curves, and their works indicate three main characteristics. First, most works predict lithofacies using features measured during … Web1 sep. 1987 · Major lithofacies groups represented in the data base include sandstones, limestones, dolomites, shales, coals, and evaporites. These are subdivided by introducing cement and special minerals and by considering porosity ranges. The construction of the data base is a critical step. church creek md restaurants
