The process of hydraulic fracturing for recovery of oil and natural gas uses large amounts of fresh water and produces a comparable amount of wastewater, much of which is typically transported by truck. Truck transport of water is an expensive and energy-intensive process with significant external costs including roads damages, and pollution. The integrated development plan (IDP) is the industr...

In terms of sharp drop of international oil prices in the second half of 2008 after heading skyward in the first half of 2008 following continual growth since 2005, while at the same time certain parity among energy prices was disrupted, the author of this article tried to investigate key factors that influenced oil and gas industry and to answer the question what would be a »fair» price of cru...

since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...

The paper presents an approach to development of the system that supports decision-making for tasks aimed to reduce power consumption of oil-and-gas production enterprise and to enhance the environmental safety of oil and natural gas production. The architecture and operating principles of such a system, as well as the classes of tasks to be solved, are discussed. Adjustment of the system to th...

the pomegranate seeds of four iranian commercial varieties  (abanmahi (ab), malas (ms), pust sefid (ps) and shahvar (sh)) were evaluated in terms of some quality properties including protein, oil, dietary fiber, mineral contents and fatty acid composition. physicochemical properties and antioxidant activity of pomegranate seed oils (psos) were also determined. the oil antioxidant activity was m...
