The technique of 3D geological modeling (3DGM) is an effective tool for representing complex geological objects. In order to improve the accuracy of geological models applied in numerical simulation methods such as finite elements and finite differences, we can use 3DGM as a modeling tool. To do this, however, 3DGMmust provide the ability to model geological and artificial objects in a unified ...

Reservoir simulation is ubiquitous in the petroleum industry, and conditioning models to production data (history matching) has become an essential job of reservoir engineers. Traditional history matching methods directly perturb reservoir properties without regard to the existing geological continuity. When the geological heterogeneity is destroyed, the result is often a history-matched model ...

Based on unascertained measurement theory, a comprehensive evaluation method to propose the vulnerability of regional geological disasters was presented in this paper. The function of unascertained measure of all evaluation indexes was established, the weights for indexes was calculated by entropy weight theory, and a result of the vulnerability of regional geological disasters has been carried...

The exploration of geological composition, e.g. underground flow path, is a significant step for oil and gas search. However, to extract the structural geological composition from the volume, neither the classic volume exploration methods, e.g. transfer function design, nor the traditional volume cut algorithms can be directly used due to its three natural properties, various compositions, disc...

The main objective of this study is to develop a prototype model of Web-based Geographic Information System (GIS) application for efficient management of borehole and geological data. More than 10,000 boreholes and other geological data were archived into the database and Web-based GIS system was implemented for a local urban area of Seoul in Korea. A standard form of borehole data was suggeste...

In this article we present a new method for seismic image restoration. When observed, a seismic image is the result of an initial deposit system that has been transformed by a set of successive geological deformations (flexures, fault slip, etc) that occurred over a large period of time. The goal of seismic restoration consists in inverting the deformations to provide a resulting image that dep...

Data collected as a part of a survey on radon concentrations from about 40 000 dwellings in England for six contrasting geological units were analysed to evaluate the impact of house-specific factors (building characteristics and construction dates) and of proximity to geological boundaries. After adjusting for temperature and outdoor radon, geological unit, house type, double glazing and date ...
