Uncertainty in production prediction has been subject to numerous investigations. Geological and reservoir engineering data comprise a huge number of data entries to the simulation models. Thus, uncertainty of these data can largely affect the reliability of the simulation model. Due to these reasons, it is worthy to present the desired quantity with a probability distribution instead of a sing...

The measurement of the minimum miscibility pressure (MMP) is one of the most important steps in the project design of miscible gas injection for which several experimental and modeling methods have been proposed. On the other hand, the standard procedure for compositional studies of miscible gas injection process is the regression of EOS to the conventional PVT tests. Moreover, this procedure d...

In the process of working face mining, permeability coal seam and crack evolution characteristics overlying strata are very important for efficient gas drainage. this study, distribution stress field in their relations analyzed mainly by 3DEC numerical simulation. Furthermore, combined with on-site measurement stress, pressure, seepage front before after coupling effect law migration deeply exp...

The current study proposes a two-step approach for pore facies characterization in the carbonate reservoirs with an example from the Kangan and Dalanformations in the South Pars gas field. In the first step, pore facies were determined based on Mercury Injection Capillary Pressure (MICP) data incorporation with the Hierarchical Clustering Analysis (HCA) method. In the next step, polynomial meta...

rapid growth and development of information communication technology (ict) has been the foundation of novel concepts and zones in this newly established field. on the other hand, the field’s novelty has caused various problems in facing occurrences and newer fields. the goal of this research is studying the obstacles of information communication technology acceptance in isfahan gas company. fro...

We observe collective oscillations of a trapped, degenerate Fermi gas of 6Li atoms at a magnetic field just above a Feshbach resonance, where the two-body physics does not support a bound state. The gas exhibits a radial breathing mode at a frequency of 2837(05) Hz, in excellent agreement with the frequency of nu(H) identical with sqrt[10nu(x)nu(y)/3]=2830(20) Hz predicted for a hydrodynamic Fe...
