The objective of this study was to determine the best way to quantify the political and regulatory risks in the oil industry. To analyze if these risks should be included in the cash flow or quantified in the WACC (weighted average cost of capital), we used real case studies of exploration and production (E&P) and refining in Latin America. The oil industry is a good case study for this type of...

oil is a strategic product in our country, iran. the amount of importing this product is considerable, and therefore, any attempt to produce crude oil in our country in a way that competes with the foreign counterparts, with regard to both quality and production cost is considered important. this study addresses the effect of oil seeds preparation step on quality of crude oil, which is extracte...

Naphthenic acids and TAN are one of the ever-increasing crucial problems in oil, shale oil and sand oil industry and also environment protection. Furtherer, they increases the corrosion of some parts of a refinery and transport pipelines and also can create nanoemulsions and make complicated the refining process especially in desalters. To prevent these problems it is important to first obtain ...

Technological Change, Depletion and the U.S. Petroleum Industry*** A common claim in the nonrenewable resource literature is that improvements in technology may largely offset the effects of increasing scarcity over time. This study provides perhaps the first empirical evidence on this issue by analyzing the determinants of the average finding cost for additional petroleum in the U.S. over the ...

This anecdotal, non-systematic review serves to explore the principles and methods of effective oil decontamination from cutaneous wounds, particularly crush injuries. The current expansion of the petroleum industry is necessary to meet increasing world demands for oil. Most stages of oil refining and applications involve significant injury risks, particularly for crush injuries that become con...

in this study,oil was extracted from the liver and visceral fat of patin (pangasianodon hypophthalmus) and refined. the yield of oil after refining was 49.98%. the major yield loss (34.20%) happened during the degumming procedure. fatty acids found in the crude and refined oil were c12:0, c14:0, c14:1, c16:0, c16:1, c18:0, c18:1, c18:2, c18:3, c18:4, c20:0, c20:1, c20:4, c20:5, and c22:6. the d...
