Fractures of multi-scales and multi-origins are primary storage space effective seepage channels for metamorphic buried-hill reservoirs. They not only allow communication between various pores to enhance capacity, but also essential high yields. Fracture development controlling factors at reservoirs Bozhong 19-6 Gas Field were investigated based on imaging log, core data, experiments, e.g., thi...

nowadays, water supply for sustainable development is one of the most important concerns and challenges in most countries of the world. due to determination of groundwater potential zones are one of the important tools in the conservation, management and utilization of water resources. thus, the present study aimed to prioritize the effective factors on groundwater potential and its susceptibil...

The site and character of precious and basemetal epithermal deposits is determined by several principal factors which include: structure, stratigraphy, lithology, pressure and temperature. hydrology, chemistry of the mineralizing fluid, and syn-hydrothermal development of permeability or changes in hydraulic gradient (White and Hedenquist, 1990). This study investigates the syn-hydrothermal dev...

the main purpose of this research was to study the variables and factors that affect adaptation of university to external environment and to develop a model for assessment of tehran public universities adaptation to external environment. a mixed method research approach involving a three-round delphi study was used to record responses to the closed-questions and open-ended-questions. other data...

-This paper based on crossplot and core data,analysis the Pu Xi oilfield ,Putao Hua oil layer ‘s conventional logging response characteristic.Based on the describe of the three cored wells, Putao Hua oil layer is mainly made up with siltstone, muddy siltstone, silty mudstone,. First normalized the well logging curves, elimination the influence of the nongeological factors to the well logging cu...

landslides and slope instabilities are major hazards for human activities often causing economiclosses and property damages. sikan river basin (ilam province) due to the topography, tectonic,lithology, and climate has enough potential for occurrence of this phenomenon. the objectives of thisstudy were to determine effective parameters controlling the landslide occurrence and to preparezonation ...
