Lithologic properties
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, and composition. Lithology may refer to either a detailed description of these characteristics, … Meer weergeven The naming of a lithology is based on the rock type. The three major rock types are igneous, sedimentary, and metamorphic.

Sedimentary textures include the degree of sorting, grading, shape and roundness of the clasts. Metamorphic textures include those … 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 main visible fabric is normally bedding, … Meer weergeven Rocks often contain small-scale structures (smaller than the scale of an individual outcrop). In sedimentary rocks this may include sole markings, ripple marks, mudcracks Meer weergeven Web31 okt. 2024 · This section presents the qualitative and quantitative reservoir parameters such as lithologic properties, reservoir intervals, volume of shale, porosity, saturation and permeability as encountered in the two wells.
