Geological maps are increasingly published and shared online, whereas tools and services supporting information retrieval and knowledge discovery are underdeveloped. In this study, we developed an ontology of geological time scale by using a RDF (Resource Description Framework) model to represent the ordinal hierarchical structure of the geological time scale and to encode collected annotations...

During history match reservoir models are calibrated against production data to improve forecasts reliability. Often, the calibration ends up with a handful of matched models, sometime achieved without preserving the prior geological interpretation. This makes the outcome of many history matching projects unsuitable for a probabilistic approach to production forecast, then motivating the quest ...

The regional engineering geological conditions and geological hazard evaluation is the important part of realizing the railway geological selection, However, the accuracy of the evaluation largely depends on the reliability of basic information and reasonable mathematical model. Remote sensing provides reliable geological information and accurately reflects the geological conditions along the r...

A wide range of methodologies and software applications have been developed to generate 3-Dimensional (3D) geological model data. One of the main open issues is the exchange of these heterogeneous data from different sources, which influences the sharing and integration of 3D geodata. It is also a necessity to take into consideration the semantics of 3D geological data to enable its full exchan...

The comparison of physical ages of geological materials measured by laboratories engaged in geochronological studies has been limited by the accuracy of mineral standards or monitors for which reported ages have differed by as much as 2 %. In order to address this problem, the U.S. Geological Survey is planning to calibrate the conventional (40)Ar/(40)K age of a new preparation of an internatio...

Groundwater contamination is a serious threat to water supply. Risk assessment of groundwater contamination is an effective way to protect the safety of groundwater resource. Groundwater is a complex and fuzzy system with many uncertainties, which is impacted by different geological and hydrological factors. In order to deal with the uncertainty in the risk assessment of groundwater contaminati...

Three-dimensional (3D) geological models are important representations of the results of regional geological surveys. However, the process of constructing 3D geological models from two-dimensional (2D) geological elements remains difficult and is not necessarily robust. This paper proposes a method of migrating from 2D elements to 3D models. First, the geological interfaces were constructed usi...

Carbon dioxide (CO2) storage into geological formations is regarded as an important mitigation strategy for anthropogenic CO2 emissions to the atmosphere. This study first simulates the leakage of CO2 and brine from a storage reservoir through the caprock. Then, we estimate the resulting pressure changes at the zone overlying the caprock also known as Above Zone Monitoring Interval (AZMI). A da...

As a provider of geological advice to industry, academia and the public, the British Geological Survey (BGS) has recognised the need to change the way it presents geoscientific information, resulting in the construction of attributed 3D geological models. The need to deliver 3D modelling solutions is of great importance in urban areas, where geological factors play a major role in supporting gr...

With the development of computer technology and geological modeling study of the gradual maturity, 3D for the engineering geological modeling and information visualization analysis system of opportunities and challenges brought about. Have carried on the detailed introduction to the three dimensional geological modeling tool and the method. Summarized the three dimensional geological modeling b...
