This work focuses on petroleum producing giants in ...

Colorado and Pennsylvania, like parallel universes, provide strikingly different examples of how external forces affect the evolution of oil and gas conservation jurisprudence originating from a common starting point. This jurisprudence includes both “Classical” oil and gas conservation—measures to prevent waste of the oil and gas resource, and “Values” oil and gas conservation—measures that ad...

one of the major environmental problems in the world, especially in iran is deficiency of water resources. this with respect to the entrance of wastewater (especially industrial wastewaters due to their toxic effects) into the water bodies emphasizes the importance of wastewater treatment. heavy metals such as cadmium, lead and vanadium are part of oil and hence are of the major pollutants prod...

The oil and gas industry will continue to boom in the coming future. Obtaining oil and gas from conventional and non-conventional resources will become more and more challenging. This intensifying need will impose very considerable demands on work force, financial and technology capabilities. Since the future supplies of oil and gas are to expand, advanced technology will become increasingly ne...

life cycle study of a product is an accepted method for determining the side effects of its production process on environment during its complete life cycle. in this research, the impacts of global warming, acidification, terrestrial eutrophication and fossil resources depletion per unit yield of wheat (ton) on environment were investigated using life cycle assessment method in marvdasht region...

Abstract:Gas export is one of the considerable choices in gas consumption to obtain foreign ex-change direct income by the government. Gas can be transformed and exported by various forms such as LNG and GTL. All forms of gar transformation and its export row gas with a convertible coefficient. Therefore, gas export means the total gas export through pipelines, LNG on the other forms of g...

The oil industry needs solid and reliable materials in almost all processes. By making nano-scale materials, lighter, more robust, and more robust equipment than today's products can be produced. Nanotechnology in the field of oil industry and its related industries, in addition to reducing the environmental hazards of this sector and the possibility of saving from harvesting of underground res...
