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,...

Three-dimensional (3D) modelling of geological body is an important issue of 3D GIS and 3D Geosciences Modelling, and one of the key technologies of digital mine. GTP model and its components are introduced in this paper. According to the relations between chronolith and rock attribute comprehensively, the modelling region, system, series, group and rock characteristics(RC) are regard as the sc...

Conditions have fluctuated a good deal in the last 'leaps' but these changes, like waves on the ocean, had little effect on the working up and down of traditional medicine which is the main element of Chinese life itself. Contradictions in a socialist society are fundamentally different from those in the old societies. Traditional medicine, a faithful reflection of Chinese culture, is a first-r...

The surface area of Venus ( 460 10 km) is 90% of that of the Earth. Using Magellan radar image and altimetry data, supplemented by Venera-15/16 radar images, we compiled a global geologic map of Venus at a scale of 1:10 M. We outline the history of geological mapping of the Earth and planets to illustrate the importance of utilizing the dual stratigraphic classification approach to geological m...

Geological mapping and establishment of stratigraphic relationships provides an overview of geological processes operating on Mars and how they have varied in time and space. Impact craters and basins shaped the crust in earliest history and as their importance declined, evidence of extensive regional volcanism emerged during the Late Noachian. Regional volcanism characterized the Early Hesperi...

In the well placement problem, as well as in many other field development optimization problems, geological uncertainty is a key source of risk affecting the viability of field development projects. Well placement problems under geological uncertainty are formulated as optimization problems in which the objective function is evaluated using a reservoir simulator on a number of possible geologic...

The geology of the Himalayas is intricated and intriguing. It features numerous tectonic bodies structures too complex to interpret. Along with such mysteries it has many common geohazards, as landslides. In this study, a detailed geological investigation carried out overcome discrepancies in structural interpretation, nature two crystalline bodies, non-uniformity mapping central Himalayan arc,...
