Since the 1950s, the pollution of reservoirs has become serious. The water quality in reservoirs is deteriorating due to population growth, industrialization, and urbanization. In order to clarify the characteristics of water quality change in reservoirs, in-situ monitoring of water quality and phytoplankton were conducted in Jinpen Reservoir, Shibianyu Reservoir, Zhoucun Reservoir, and Zhelin ...

this paper describes the problem of sedimentation in reservoirs,in general, and offers an estimate of the annual rate of storage loss and the useful life of sefidrud reservoir in iran,in particular. the life of sefidrud reservoir was predicted to exceed 100 years in the design, based on insufficient data. regular daily measurements of sediment discharge of the river, taken years later, however,...

Reservoir porous medium is random, in terms of oil and gas for low permeability reservoirs. Consider the random nature of the reservoir will enable to improve the accuracy of numerical reservoir simulation. Based on extensive research, for the stochastic nature of the reservoir from the two aspects of physical simulation, numerical simulation, the relevant international studies were reviewed. T...

Finding a representative fluid in a hydrocarbon reservoir is crucial for integrated reservoir management. In this study, a systematic approach for screening and selecting consistent fluid samples in a reservoir was developed. The model integrated quality control (QC) of well conditioning before sampling, QC of PVT data, thermodynamic modeling and compositional gradient within a reservoir. Well ...

An accurate reservoir characterization is a crucial task for the development of quantitative geological models and reservoir simulation. In the present research work, a novel view is presented on the reservoir characterization using the advantages of thin section image analysis and intelligent classification algorithms. The proposed methodology comprises three main steps. First, four classes of...

Sarvak Formation as the oil reservoir with the most hydrocarbon potential in Yaran oil field is of special importance. The present research was conducted to study the reservoir parameters of this Formation. For this purpose, petro-physical crude data was first prepared and using the Geolog6.7 software, a petro physical plot was drawn. Afterward, petro-physical properties of reservoir were done ...

2/3 of the reservoir surface area was approximately covered with dense populations of Myriophyllum, Ceratophyllum and Potamogeton species. The headwaters of the reservoir were considered as hard water and had both carbonatic and non-carbonatic hardness. When they were exposed to lentic condition of the reservoir and its intensive photosynthetic activities of macrophyte communities, the bicarbon...

Flow unit characterization plays an important role in heterogeneity analysis and reservoir simulation studies. Usually, a correct description of the lateral variations of reservoir is associated with uncertainties. From this point of view, the well data alone does not cover reservoir properties. Because of large well distances, it is difficult to build the model of a heterogenic reservoir, but ...
