Iran’s environmental condition is critical, since it is experiencing desertification, unsustainable development and overpopulation. The objective of this study is power source replacement in natural gas stations that operate with natural gas compressors, through using electrical motors, which can be fed by a 160 MW geothermal power plant, as an alternative to gas turbines. Application of such a...

در حالت کلی معادلات حاکم بر یک مدل ریاضی از مخزن را نمی توان بوسیله روشهای تحلیلی حل کرد، در حالیکه یک مدل عددی می تواند بوسیله کامپیوتر جوابی تقریبی ارائه دهد. در این پایان نامه، یک دستگاه معادلات دیفرانسیل معمولی توسط گسسته-سازی معادله حاکم بر جریان شعاعی تک فازی نفت بسمت یک چاه (معادله چاه آزمایی) به دست آمده است. این سیستم شامل محاسبه تابع ماتریسی (exp(ka است که در آن k گام زمانی و a ماتریس...

Engineering estimates of methane emissions from natural gas production have led to varied projections of national emissions. This work reports direct measurements of methane emissions at 190 onshore natural gas sites in the United States (150 production sites, 27 well completion flowbacks, 9 well unloadings, and 4 workovers). For well completion flowbacks, which clear fractured wells of liquid ...

Today there is consensus regarding the importance of predicting the price of energy carriers for economic development, including natural gas as a preferred energy source on environmental grounds. In this paper we analyze the nonlinear behavior of natural gas prices over time by use of the Grey Method (GM), Developed Grey Method (DGM), Fractal Discrete Grey Method (FDGM) and a compound Method II...
