Since the beginning of 1993 our group is a member of the SFB \Interactions of Continental Substance-Systems and their Model-ling" 1. In this interdisciplinary project about 20 groups of the University of Bonn, mainly geoscientists, are participating. To provide the SFB with database technology as soon as possible, we decided to develop GEO-STORE, a rst prototype system which is restricted on th...

Reliable characterization of subsurface soil in urban areas is a major concern in geotechnical and geological engineering projects. In this regard, this research deals with development of a 3D geological engineering model on Mashhad City soil using Sequential Gaussian Simulation (SGS) approach. The intense variability of soil in the study area has sometimes caused serious problems in civil engi...

14 The Geological Surveying and Investigation in 3 Dimensions (GSI3D) software tool and 15 methodology has been developed over the last 15 years. Since 2001 this has been in 16 cooperation with the British Geological Survey (BGS). To-date over a hundred BGS 17 geologists have learned to use the software that is now routinely deployed in building 18 systematic and commercial 3D geological models...

The Sim-SEQ project coordinated by the Lawrence Berkeley National Laboratory (LBNL) aims at providing a comparative study of different conceptual models with respect to predicting the behavior of CO2 geological storage operations conducted on a reservoir formation, while using the same database for site characterization. The S-3 site has been selected for conducting such a comparative study. Al...

The current metadata modeling techniques can not meet the needs of knowledge conception expression, knowledge organization, and metadata semantic consistency in geological domain. This paper introduces ontology and integrates this theory to geological domain metadata modeling. It adopts the first order logic equivalent algorithm and defines the metadata extended model as a quaternion group whic...

Advances in virtual globes and Keyhole Markup Language (KML) are providing the Earth scientists with the universal platforms to manage, visualize, integrate and disseminate geospatial information. In order to use KML to represent and disseminate subsurface geological information on virtual globes, we present an automatic method for modeling and visualizing a large volume of borehole information...

The inverse-distance weighting interpolation is widely used in 3D geological modeling and directly affects the accuracy of models. With development “smart” or “intelligent” geology, classical cannot meet accuracy, reliability, efficiency requirements large-scale models these fields. Although improved can basically it at same time. In response to limitations, adaptive method based on attribute s...

The geological interpretation of gravity gradiometry data is a very challenging problem. While maps of different gravity gradients may be correlated with geological structures present, maps alone cannot quantify 3D density distributions related to geological structures. 3D inversion represents the only practical tool for the quantitative interpretation of gravity gradiometry data. However, 3D i...

Fractures have crucial impact on flow in reservoirs. In naturally fractured reservoirs (NFR) the fracture network alone can be the dominant factor in fluid transport. Fractures as geological discontinuities introduce a high level of complexity into the entire reservoir modeling workflow. In current practice, the geological modeling of fractures and flow simulation are considerably disconnected,...
