various sources of geodetic, geological and geophysical information can improve our understanding about the crustal density. in this paper we propose a methodology for determination of crustal density based on terrestrial gravity observations, geopotential models, digital terrain models (dtm), geological maps and cross-sections, deep geophysical profiles, and geoid models. the method can be alg...

The problem of estimating the location of facies boundaries is difficult in history matching, partly because of the geological complexity. The truncated plurigaussian method for modeling geologic facies is useful in this aspect not only for the wide variety of textures and shapes that can be generated, but also because of the internal consistency of the stochastic model. This method has not bee...

The developing cyberinfrastructure affects the knowledge system by which geological surveys collect, represent, and communicate their knowledge, and thereby influences their view of the geology. Consequences for four interacting aspects of the overall system (infrastructure, business models, geological framework, and surveying methods) are outlined. Although each reflects a different area of ex...

The final products/maps of any synergistic geo-scientific interpretation project of an E&P company are stored as CGM (Computer Graphics Meta) files. These include (1) time and depth maps at various levels and (2) maps of sand extent and thickness in established or development fields used for reserve estimates. Normally, CGM files for maps of former type are generated in various interpretation w...

To investigate pedological criterion on land degradation in Quaternary rock units, at first, a part of the shoor watershed area was selected. After distinguishing target area, slope classes, land use and geology maps were created, then map of units were founded by overlaying and crossing these maps. In this research three indices of erodibility, salinity and permeability of soils were considere...
