The aim of this study is to characterize and find the location of geological boundaries in different wells across a reservoir. Automatic detection of the geological boundaries can facilitate the matching of the stratigraphic layers in a reservoir and finally can lead to a correct reservoir rock characterization. Nowadays, the well-to-well correlation with the aim of finding the geological l...

Detailed information about geology, hydrogeology and seismic hazard issues for Umbria region are contained in a spatial database available as open data format (shapefile or KMZ) and distributed under the regional open data portal called Open Data Umbria ( http://dati.umbria.it ) where 297 datasets have been produced by Umbria Region until now and most of them are made by Geological Survey. Geol...

A project designed to gain access to all usable data to aid construction of 3D geological models for southern Manitoba has included signifi cant effort to appropriately utilize lithological data of variable quality in the Provincial water well database known as “GWDrill”. In order to use the data, it was necessary fi rst to assign x, y, and z coordinates to each site on the basis of the existin...

Over the past two decades, a series of sophisticated three-dimensional modeling technologies – collectively identified as Geoscientific Information Systems, or GSIS – have been developed to address the need for a precise definition of subsurface conditions (Turner, 1991). Geological modeling requires the extension of traditional GIS methods (Turner, 2000; 2006) and the modeling process remains ...

various geological units in an area often exhibit different magnetic properties. due to this distinction in magnetic properties of the geological units, a correlation between the type of a geological unit and its magnetic response can be established. to determine the lateral and vertical extents of geological units from the magnetic data in a survey area, a number of filters for processing magn...

The Middle Jurassic (Bathonian)-Upper Cretaceous (Maastrichtian) deposits exposed at the southern front of Central High Atlas (CHA, Southern Morocco) include thick fluvial successions largely undifferentiated in previous studies. These continental strata record a long period relief formation due to crustal shortening and subsequent denudation that predated Cenozoic, syn-collisional, tectonic in...

The nomenclature. development of the Phanerozoic rock units mentioned in the stratigraphic lexicon of Yemen is revised. Forms violating the nomenclature rules are corrected in accordance with the nternational rules of the stratigraphic nomenclature. The concerned forms are categorized as: informally introduced, dropped, named or re-named units, all of these categories are discussed in detail.
