Lithologic sequence
Webresistivity logs, porosity logs etc. to obtain lithologic sequence. Log cross plots such as compensated neutron log and formation density compensated log will be used to accurately determine the true formation porosity of the reservoir. Porosity determines the storage capacity for hydrocarbons and permeability determines the fluid flow WebThe geological surveys are needed especially in the hillside and mountainous areas having as final purpose the identification of the underground geological structure, the lithologic sequence, systems of downthrouws and fissures, delimitation of useful rocks areas, landslides, etc. ParaCrawl Corpus

Use of ‘facies’ is ambiguous—sometimes refers to particular body of rock (a NADM geologic unit), sometimes refers to a ‘kind’ of rock body characterized by some internal sequence of rock types and the presence of various geologic (typically sedimentary…) structures. Lithostratigraphic unit (NADM)
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 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 including carbonates, calcite-cemented rocks or those with possible calcite … 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 main visible fabric is normally bedding, … Meer weergeven The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic. Igneous … 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 … 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 The texture of a rock describes the relationship between the individual grains or clasts that make up the rock.
