abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Wetland ecosystems have many economic and ecological functions and values, but today their security and existence have been heavily influenced by various natural and human factors. Therefore, the present study was conducted to identify, rank and assess environmental risks threatening Khur-e- Azini International wetland located in Hormozgan province. In order to identify risk factors, the Delphi...

Researchers in China have tended not to distinguish between conventional and unconventional oil, leading to inaccuracies in their estimates of future oil production. The purpose of this paper is to make an accurate estimate of the pattern of China’s future oil production, by properly distinguishing between these oil types. We make our analysis by treating conventional oil as a single category, ...

Heavy fuel oil (HFO) category substances are used to manufacture HFO, a product used in industrial boilers and marine diesel engines. Commercial HFOs and blending stream components are substances of complex and variable composition, composed of C20 to >C50 hydrocarbons, although lower molecular weight material may be added to reduce viscosity and improve flow characteristics. An HFO blending st...

More than 600 million pounds of the soybean oil produced annually in the United States are used for nonedible applications, including the production of industrial materials (American Soybean Association, 2001). More than half of this use of soybean oil falls in the category of fatty acids, soaps, and feed. The remainder of the nonedible soybean market is used for the manufacture of inks, paints...

Introduction Exposure to chronic levels of ionizing radiation could be detrimental to health even at very low doses. Calabar free trade zone (CFTZ) was established to promote export business in Nigeria and it is yet to produce exposure data of the Zone. Materials and Methods The Zone was divided into three categories depending on the type of business. Category A had facilities with manufacturin...

BACKGROUND Temporal and spatial expression of fatty acid and lipid biosynthetic genes are associated with the accumulation of storage lipids in the seeds of oil plants. In jatropha (Jatropha curcas L.), a potential biofuel plant, the storage lipids are mainly synthesized and accumulated in the endosperm of seeds. Although the fatty acid and lipid biosynthetic genes in jatropha have been identif...
