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, or a summary of the gross physical character of a rock.

"WebThere are several ways of describing or designating sedimentary facies. By noting the prime physical (or lithological) characteristics, one is able to recognize lithofacies. The biological (or more correctly, paleontological) attributes—the fossils—define biofacies. Both are the direct result of the depositional history of the basin. " - Lithofacies

Lithofacies such as grainstone, wackestone and packstone are expected to be dominant in the area due to their hydrocarbon-bearing properties. This map is useful in choosing future-planned drilling wells. WebCreation of lithofacies maps was done using seismic facies analysis and lithofacial well log cluster analysis method. Obtained lithologies were modified using calibration data for porosity and permeability derived from well-log data and in that way were made more than 800 lithofacies maps in all models.

Webframework of fluvial deposits, step by step, starting with lithofacies, combining these into architectural elements and other facies associations, and then showing how these, in turn, combine to represent distinctive fluvial styles. Next, the discussion turns to problems of correlation and the building of large-scale stratigraphic frameworks. WebA high-fidelity lithofacies model in Louisiana and Southwest Mississippi was then constructed using over 35,000 well logs, given the dip variations of hydrogeologic units. The modeling technique involves discretization, domain transformations, and interpolation. The hydrostratigraphy produced by the lithofacies model was validated by literatures.
